I am grown dude i said my opinion i didnt even swear its not i just said concidering the fact that the emulator can make a 720p screen run at 2k how can we make sure that this 4k is really 4k? Native and not virtual... You say using the right apps its really 4k how can u be so sure? I ran youtube vid on 2k on a 720p screen emulated to 2k so how does that prove anything?

Btw im not mad at the developers in here the other poat stated the sick comunity of unthankful people who are accusing them of not doing a good job, im not mad at them im mad at sony. If i was right with you people would you look me in a straight face telling me you really think this 4k screen looks sharper than the z3? (1080p) dont answer before you check, cuz i did, on 4k enabled, compare it to the z3 and it looks less sharp, and the z3 has whiter whites so i paid for this device cuz of how sony advertised its screen being the best since its 4k but it actually isnt as good so maybe youre mad at me for hating but i paid loads for this concidering what in can deliver according to the advertisements of sony but in actuality it doesnt show it...

I said maybe i could be wrong about the screen not being a native 4k, but even if im wrong this doesnt look 4k to me, look me in a straight face and tell me this actually looks 4times sharper than any other 1080p screen. If you cant tell me that dont judge me for being mad cuz i paid for 4 times 1080 screen and all i got is worse sharpness with pixelated grids
[Sony Xperia XZ Premium Guides, News, & Discussion] madshark2009:
No im not a bit off over the devs they are doing a great job im not hating on any dev nor their work cuz this device is a pain in the behind to root it and use it properly.

Im mad straight at sony.

How can u really prove its really 4k? Even if u do, does this screen look sharper than 1080p screens? For god sake i can see pixel grids i get cuz of the pattern of the pixels but i paid for a. 4k screen and i dont understand how you can actually say its sharper than other 1080 or 2k phones.. It isnt i can show you pics of it going against the z3 and the samsung and the htc and this is supposed to have the best screen of all? Im sorry if im coming out as a pain dissing the device but im saying the truth in my eyes and this doesnt look anything like I expected from a 4k screen to deliver... The worst i expected is for it to not be worse than 1080p phones.. But its even worse so im really disappointed.

So your judgement is derived from 'limited' tests using an emulator and your visual perception, just because the difference is not discernible to your eyes you believe it is a lie, fair enough, that is your opinion after all. But to come to that conclusion again by limited means of testing, that does not stand true against what other people have tested and examined and again, peoples perception differs, whether it is a figment of someone imagination or a actual fact, but people can see the crispness, clarity, sharpness or whatever you words you want to use.

I myself do not game, watch videos, skype or so on with my phone, I use it purely as a phone, a means of communication and the few times I have displayed 4K content, I have been clearly able to see the difference in what I am looking at, but that by using 4K .MKV files from my NAS and 4K images, maybe, just maybe that is because I do not spend more than a few minutes at a time looking at the screen of my phone, and spend less than an hour a day actually using my phone. Who knows.
[Sony Xperia XZ Premium Guides, News, & Discussion] madshark2009:
well im not just using "an" emulator im using the only way to show the device in 4k all the time. have you seen youtube videos on "how to enable 4k at all times" which means not just apps that support 4k but all the phone. so my point is using this emulator, the device is not naively 4k, proven! I provided pics of z5c running at 2k when its a 720p, im just saying this is not a native 4k method.

my second point is, yes after running this particular method the device does look sharper than it was, but not sharper than other devices. sharpness is not a matter of opinion nor imagination, if it was a color problem i could be color blind yes, but sharpness is not a personal opinion, its a fact. maybe a few tests arent enough but having an old phone as old as the z3 showing crisper images on instagram and almost any other app or picture, with better white balance against this so called premium phone with supposedly 4k screen just doesnt sit tight in my expectations in fact its worse than the worst you can expect...

not just the z3, but the s8, z5 premium, these are devices i have hold of to compare but if these devices have crisper image than this 4k then you tell me sony didnt lie to us...

and I also have a samsung s5 phone and i went to youtube, got into "4k wild animals" video put on my xz premium 4k settings, and 1080 on the s5 and the s5 looks just as sharp and on some edges even sharper.

does this make sense to you? maybe youre not believing me because there are no display comparisons for this device against others, except the s8, which evidently the s8 has a sharper display (the XZ premium is stated as more realistic but less sharper) so people cant really tell a difference and id be happy to post pictures of comparison.

PS: just a thing to think about for you, do you really think I would go through this much trouble and time trying to prove the device is actually 4k, if the device was as pleasing as I expected? why would I bother? a 4k screen would make you go "GOD DAMN THIS SCREEN IS AWESOMEEEE!" and not "HMM seems fishy I think I should check that out". just saying you should think about that.
[Sony Xperia XZ Premium Guides, News, & Discussion] Mobfigurz:
I think you may have missed something, the phone is not running 4K full time and if you looked into it before purchase as most 'enthusiasts' do, you would research a device before taking the plunge and splashing out large amounts of money. I purchased my XZP a month or so after launch, after having read many reviews and visited this section of XDA as I had the Z5P before this and I was aware, even from the Z5P that 4K was an 'on-demand' feature only utilised by certain applications. So there is that, but also on your point of clarity, I cannot say whether you are right or wrong in comparison to other devices as I solely use the one phone and only have the need for one phone so there would be no need for me to 'check' against other phones as it does not matter to me how other devices perform, I own a XZP.

I do understand what you are getting at though, the problem is, you have placed far too much emphasis on how other devices perform and to be frank, there are not a large number of people who are in the same boat as you, you may find some feel the same way but look at the majority of users on XDA of the XZP, they have no complaints and even the Devs who I assume are far more knowledgeable than both of us are fine with the XZP.
[Sony Xperia XZ Premium Guides, News, & Discussion] Mobfigurz:
There are other ways to enable 4K or even 2K on the phone via ADB I believe, take a look around the forum and you might find a better way to run it rather than the emulator.

I have never looked into it myself because I am satisfied with the phone and do not want 4K to be always on and drain my battery. Also, that is another consideration Sony factored in, as on the Z5P and the XZP, 4K and battery life need to coexist, and though the screen is of course a major feature as advertised, they have to find a balance as not all consumers are like us XDA users, most people do not root their phones and mess with them like we do. You have to remember that also, we would love certain features but we need a balance, the XZP could have been even bigger and heavier if they had constant 4K and a larger capacity battery to support it and provide enough juice to last 2 days, you have to remember that battery charge times, in-call and standby times are also major factors, people do buy because of battery life expectations, having to charge less, having greater freedom of usage and not having to worry about charging every hour.
[Sony Xperia XZ Premium Guides, News, & Discussion] madshark2009:
Yah i guess youre right.

The adb is the emulator im talking about.

Yah the phone i awesome after all, even on youtube on 4k i thought it would be more crisp, it is pretty crisp and sharp but i expected more on 4k display thats what dissapointed me cuz my s5 in youtube on 1080p is sharper than ny xz premiun on 4k in the same video so it kind of bugs me..

Overall the quality of the display and colors produce a more natural display but when it comes to sharpness i expected better.
[Sony Xperia XZ Premium Guides, News, & Discussion] Mobfigurz:
I completely understand where you are coming from, you built up your expectations from the way Sony advertised the device, the main selling features but it fell short of your expectations, unfortunately, that can happen a lot and there is little we can do about it, I believe the majority of users feel that way about at least one thing on the XZP and that seems to revolve around the Camera itself and how the quality of images is inferior to other manufacturers using the same Sony camera.

Maybe you can go to a store and compare other Sony devices against your expectations for your next purchase, maybe you can save yourself some money and find a 'cheaper' device that meets your expectations because we know how expensive the XZP was and who knows if the next 'Premium' device will be any better.
[Sony Xperia XZ Premium Guides, News, & Discussion] madshark2009:
yah Im from Israel, we almost dont have any store that shows you the device before purchasing, you just go to the store and ask for what you want to buy and you cant open any thing before purchase...

so I cant really compare and sony isnt famous in israel when it comes to phones so its hard to find some one who has sony to compare with so I rely on the internet.

I actually checked some youtube videos on speed test against some flagship devices from other manufacturers and I noticed that the xzp does have a crisp screen (could be the camera not catching the best angle for the displays) so in my conclusion all the manufactures are using QHD and UHD displays but their previous devices that has 1080p have crisper displays,either that or before they used over-saturated amoled displays that made the screen look sharper but now are using more natural image producing displays less saturated which caused our eye to believe its less sharp, I dont really understand, still I expected better.

yes camera is inferior due to lack of OIS but in videos in the morning it does perform better than all in my opinion, still hold the device in a tripod it will perform just as good even at night...

Yet Sony is the main camera provider for most of the other manufactures and yet sony devices have lower quality than all, just doesnt make any sense, here I ask my self this question:

Is sony doing this because they get more money from other manufactures buying their camera than costumers buying their phones? maybe they have a contract on which sony is not allowed to produce better images than its competitors otherwise they would stop buying cameras from them? - I actually read that some where...

[MENTION=4800693]madshark2009[/MENTION] Just download AIDA64 from play store.. it reads the hardware spec of the display panel. it clear says the screen resolution is 2160*3840. i guess this answer your question. FYI - this is shown as this while you are running the phone even at stock 1080p mode. so calm down mate XD
[Sony Xperia XZ Premium Guides, News, & Discussion] madshark2009:
Yah bro im calm i do believe its a 4k display.

But:

Its only used in a couple of apps.

And no, adb commands dont turn it to NATIVE 4K.

So yayyyy native 4k is only enabled in 3 apps.

Thats ok to you? They didnt even include an option for us!

Sony stricted using 4k at all times! Heck the display is even a 120hz display and its not even enabled! Aosp reads the screen as 120hz but no one knows how to activate it!

So yah we have 4k display but only used in 2-3 apps and not even in the UI! So yah to me they lied cuz i paid for 4k, not for "sometimes 4k" so really samsung has 2k but at least you can use google chrome in native 2k or instagram or the UI or any thing! Now thats some real 2k! And they add an option to lower!

So why sony stricting us? To me i concider their work not the best in these terms.

And btw read the comments before posting
[Sony Xperia XZ Premium Guides, News, & Discussion] sylaw:
now that i do agree with you my man.. but then again we have to think of it in multiple ways.. im pretty sure sony was scared of general performance issues and people will nag about it. all and all one pro member here pointed me out that there is a oreo asop rom which utilizes the panel and render the entire ui and apps in 4k ( its a dynamic resolution changer embedded with the kernal) . you should try that :p

i got my phone like a week ago... will run stock for a week or two more and will start taking the virginity away to try this.
[Sony Xperia XZ Premium Guides, News, & Discussion] madshark2009:
yah but its still not functional as i read it needs more modification.

and true, it could make performance drop dramatically, but they should add that in options like a switch, and when you enable 4k, a message should appear and say "you may notice stutters and a drop in performance, please do not use for high graphics games to enjoy overall performance" or some thing like that, that way the customer can choose whether to give up on performance for graphics or give up on graphics for performance, I mean its really not that laggy when just surfing the device, and then you can just switch to 1080 when you game, I dont know why they wouldnt do that...

Im waiting for [MENTION=4756773]Miustone[/MENTION] he has a good project coming up and ill see the feedback on battery, camera, display and if its worth it then ima give up my warranty.
[Sony Xperia XZ Premium Guides, News, & Discussion] sylaw:
Thats great.. please do notify me when the project is done .. i want to be one of the first to test it as well.. cheers mate
[Sony Xperia XZ Premium Guides, News, & Discussion] Atrax2010:
Pretty much all reviewers that are even somewhat relevant on Youtube outlined that the UI and most of the apps aren't really rendered in 4K.

I was aware of this information when the phone wasn't even released yet, some reviewers got their review samples early, and they noticed that right away, they probably got that info in the reviewer's guide Sony gives them as well, so I cannot imagine how you managed to avoid this very important piece of spec, if you've done the research before purchase, as you said. I haven't seen an XZP review that didn't mention that. If there is one, it's a bad one.

I don't know about you guys, but I don't even consider buying the latest model in the first four to six months of the release, until the dust settles and user reviews come out. I'm not paying that kind of money to be an early adopter. Also, in six months, the prices go down a lot, specially with Sony.

So, my somewhat-informed opinion is that no, Sony did not lie about the screen. Sure, it wasn't specified in the spec-sheet, but still, it was a well documented "feature" upon the release.

And the fact that it's a 120Hz panel, means nothing and doesn't necessarily mean you can run it at actual 120Hz. You might, but it's not a guarantee. Its' just the panel.

I bet you plenty of premium phones out there have panels that are capable of 120Hz, or even more, but to actually enable that and make it work as it's supposed to is not that simple and I'm sure if Sony could pull that off, they would. Because bigger numbers in spec sheets sell phones, bigger numbers are better. Always. Specially in spec sheets.

I know for a fact that my desktop monitor's panel is capable of 100HZ at least, 'cause I have the same panel in my other monitor that runs at 120Hz. But everything else apart from the panel is very very different in those two monitors. Panel alone doesn't make a screen/monitor.
[Sony Xperia XZ Premium Guides, News, & Discussion] madshark2009:
yes i have done my research, but only after a long period was it discovered that the ADB commands only run it in 4k VIRTUALLY which I didnt think it would be that way (and a lot of others still dont even know what virtual is)

i thought it was native, some thing that makes our device more special than others.

ive seen lots of reviews where they claim this mod is actually 4k because SONY said so, but its not native, so its a lie.

ask in sony forums how to enable 4k at all times, they give you this method and its not even native and they are telling customers its real 4k. you tell me thats not a lie?

I dont care how virtual 4k looks like, I could have bought the samsung having native 2k. I could have bought the HTC or the iphone, I could have even stayed on my previous phone and used the commands and run it at 2k/4k, whats the point of paying extra if you only get native support of 4k for a couple of apps? I actually thought only the XZ premium is 4k so when I had my z5 compact with a broken screen I was like "hey why spend much money on fixing? looks like the new phones are all coming 2k/4k why stick to 720p??" so i bought the xz premium cuz I felt like im oldschool I wanted an upgrade, but if i knew this method works on my z5c I wouldnt have thought of buying a new phone I could have just paid 50$ and got it fixed.
[Sony Xperia XZ Premium Guides, News, & Discussion] amakuramio:
why would you use 4k in everything? it will slow down the device and eat battery!

most of the time 4k is used in ''some'' videos on youtube, but most people shoot in 1080p max because of storage issues

then we watch adult videos, but most videos are low quality or max full HD anyway... you can get 4k videos and play them as well.

then images, like image gallery, those are displayed 4k.

while making screenshots I can see the display is usually at 4k resolution, so your points are invalid anyway.

120 hz will come sooner or later, maybe in android P. maybe it causes battery drain and thats why Sony disabled it.

most people are technological illiterates and just look at raw performance and battery life: xz premium delivers. Just imagine 4k all the time with 120 hz on, and battery lasting only 3-5 hours, people would never buy sony again.
[Sony Xperia XZ Premium Guides, News, & Discussion] madshark2009:
no lol there is no 4k@120hz

*i meant we need an option of either 4k screen or 1080p@120hz or the normal 1080p@60hz and one can simply choose what suits their needs.

*I know it could slow the device, but a lot of people are using the ADB commands mod and its working fine, for me as well and the mod takes more power than native 4k so yah it wouldnt be such an issue.

*you are right, gaming at 4k lets say is very hard on the device, could cause lots of heat and stutter, but if we have the option as a switch, we can simply switch to 1080 when gaming, and when using on simply browsing the device, instagram, chrome etc its nice to make it in 4k, sharp fonts, pictures, clear images you know? thats the point

plus if we had a 1080p@120hz it could also be very helpful for gaming, games would be so smooth and responsive, so will the UI.

so thats my whole point.
[Google Pixel Questions & Answers] kerryh420:
Hi all. Have come across a few threads which are indicating that 8.1 can be rooted by flashing supersu via OTG USB. Then the external are others who say it's not possible.

Does anyone know of circumstances where they or someone they've read about has successfully flashed supersu in this manner (OTG USB)?
[Google Pixel Questions & Answers] KittyRgnarok:
I highly recommend using magisk as it has an easy universal installer and comes w much more features than SuperSU along with a module repo to add functionality to your device
[Google Pixel Questions & Answers] TENN3R:
SuperSU did a great job, but now it's kinda dead. Magisk has a lot more support and updates, also is more easy to manage/update. I really recommend Magisk.
[Google Pixel Questions & Answers] kerryh420:
I am able to easily get majisk to install but it won't work with a majority of the app I frequently used such as wifi-tetherAP, ti backup, and few others. The apps will install and root permissions are granted but apps don't work as they should.

Why do they not play nice w majisk?
[Google Pixel Questions & Answers] KittyRgnarok:
They work fine for me. Do you also have the magisk manager app to actually allow the su prompts cuz I know a few times when I flashed magisk the app never showed up and I had to manually install it
[Google Pixel Questions & Answers] Horgar:
You cannot root 8.1 with supersu. You have to use magisk. And Magisk works great.

Unfortunately chainfire has retired from the scene, at least for now, and there are obviously tensions with the new Chinese owners of supersu. Supersu is not being updated and the new owners are nowhere near as responsive to users as chainfire was. He's a big loss. And magisk has its own advantages. It's systemless, works reliable and great with 8.1 and is frequently updated. I would switch to magisk. Its the future when rooting your phone.
[Google Pixel Questions & Answers] kerryh420:
Thanks for the in depth explanation regarding chain fire, supersu, and the Chinese. Such a shame they got the privilege to assume such a legendary tool for Android and they don't have the decency to support it as it should be. Alas, all great things must come to an end. Looks like it's time to7 move along and embrace the future, as you said, and get on board w majisk.

My only issue w majisk is that several of my favorite apps, the most needed one being AP-tether w root, does not work properly w majisk. It will start but other devices can not "see" the network. I've made sure that it's not hidden.

At a loss to understand why majisk can't get this app to work like supersu did... Anyone have any thoughts?
[Google Pixel Questions & Answers] Horgar:
Have you tried a clean install? Start all over with latest Feb factory image, full wipe, Inc data and then flashing twrp, magisk etc? Can't think of anything else. Magisk doesn't pass safety net so Google pay doesn't work, but give it time. Magisk is your only root option anyway on 8.1 whether you like it or not.
[Asus Zenfone 5Z  Guides, News, & Discussion] Soufiansky:
Asus recently announced their new flagship at a pretty aggresive price, for around 500$ you're getting an S845 with a big 19:9 ratio screen, dual camera, nice design ( maybe ruined by the notch ), you think the 5Z can compete with the Oneplus 6 ?
[Asus Zenfone 5Z  Guides, News, & Discussion] Ace42:
My opinion is that it's an iPhone X clone, there's no way around that. However, it's priced competitively and undercuts several SD845 devices. The only downsides really, would be Asus' track record with major OS updates, as well as their skin. I had the ZF2 3yrs ago and wasn't fond of their UI.

I'm sort of fascinated by the design, but I'm worried about development being DOA and the BL being locked. Also I want the normal ZF5 with the SD660 if it's below $300.
[Asus Zenfone 5Z  Guides, News, & Discussion] cheeze.keyk:
the specs looks good in my opinion.

maybe the only downside was the UI and development. ZF3 and ZF4 got only few roms.

but the device is running android Oreo now.

I'm eyeing now this device because of the wide angle lens, maybe this will be my replacement for my LG G5. I'm hating LG now for having select variants with unlockable bootloader and poor quality of the device.
[Asus Zenfone 5Z  Guides, News, & Discussion] Ace42:
In the US you have to buy the carrier free variant, but development is lackluster for LG phones now. V20 and G5 have some support, whereas previous LG models such as the G2-G4 saw more development. Sorta doubt things will pick up for the V30.

I'm hoping the ZF5's price will attract devs, especially those from oneplus devices.
