[Xperia Z2 Q&A, Help & Troubleshooting] One Twelve:
What is the ambient temperature where you will be shooting ?

---------- Post added at 05:54 AM ---------- Previous post was at 05:52 AM ----------

It isn't from what i can see and i'm trying to figure it out.

Go on then. Tell us what was the ambient temperature when you recorded those vids ? particularly that half hour long 1080p one.
[Xperia Z2 Q&A, Help & Troubleshooting] jawang26:
Yeah I know, I got a Z1 Compact as primary would like a Z2 eventually for those times I want a bigger screen :)
[Xperia Z2 Q&A, Help & Troubleshooting] irishrally:
Get the Z2 tablet.
[Xperia Z2 Q&A, Help & Troubleshooting] jawang26:
Haha I have an iPad already (don't judge!) like having a different eco system...We'll see hopefully I can hold out of the Z3 or Sony releases something similar in the 4.7 - 5 range.

As of now the Z2 is the best phone I've used compared to the S5 and the HTC One M8 but everyone has different preferences and tastes :)

I wrote a FULL REVIEW of the Xperia Z2 here - http://bit.ly/1kPjBJP

Read it and i'm pretty sure you will make up your mind easier. :)
[Xperia Z2 Q&A, Help & Troubleshooting] Somnium1:
Ambient temp is around 30-40C (Sometimes more). Summers are hot here.

And I still can't understand.. the overheating issue occurs in 1080p videos too?? Or just for some..?

If it's only with 4K I can live with that, but 1080p... sucks.

It's weird that no serious mobile reviews mention that.(Engadget,GSMarena,etc.)
[Xperia Z2 Q&A, Help & Troubleshooting] ProdigalFather:
Around 11-13C for both.
[Xperia Z2 Q&A, Help & Troubleshooting] skr_xd:
Any Middle east user out there? How is the heat problem with z2 as ambient is around 45+ C
[Xperia Z2 Q&A, Help & Troubleshooting] funky0308:
I'm reading answers here and it's very annoying to see some of them...

Most of us choose one brand and stick to it, why?

Just because we found something on that brand that cannot be found on others.

To compare touchwiz and Sony UI is... Hmm...let's say odd..

Why to compare?

I like Sony UI and I'm using Xperia devices, for years.

I don't like touchwiz so I don't use it.

Sony UI isn't outdated, dev brought UI on XS and older devices back in 2012/2013 but it wasn't meant to be for those devices.

Sony UI (new UI) was built for Honami, for Z1 and that's not old guys...

I thought I won't buy Z2, I own Z1 and Z2 now and I can't tell which one is Z2 from distance...so, yeah, there's not much new when you look device while it's off.

But...

When you take Z2 in your hands, when you feel it, when you see that fantastic IPS screen - you'll see the difference.

While I'm talking about screen I'll say just a few things about heating, not overheating.

If you watch 4K video or shoot one, play heavy games - it'll be hot, quite hot but there'll be no apps crashing or device freezing - that's the difference between heating and overheating.

That's perfectly normal and I'm sure next update will reduce that a bit...

Also, screen is a bit dark and you'll have trouble to watch video outside on bright sun.

You won't see problems in menus and other apps but video is hard to watch...

That's minus, at least for me...

But that's something next firmware releases could fix without any problems.

Even custom kernels could fix something like that...

If you can wait, wait for next Xperia device, it'll be better, that's for sure.

But comparing this device with Z/ZL/ZR/Z1 I can say this is not just a better device, Z2 is something new from Sony...

Believe me, I'm using Z1 at the same time and comparing them all the time - Z2 is really, really something else...

Is it better then competitions flagships?

For me it is but if you like Sony and their ideas it'll be best for you as well...

---------- Post added at 11:58 AM ---------- Previous post was at 11:55 AM ----------

Wait for a new update and we'll confirm if that heating is fixed.

55 has that problem and I think next one has it to (I think it's 402 or 420, I'm not sure) so next firmware update could fix that problem.

Wait for that and you'll know...

BTW, I just tried to shoot 1080 / 60fps video.

I recorded 3.20mins and played it, so it's almost 7 mins of 1080p videos and no heating at all.

Device is just a bit warmer (top back) but that's nothing.

It's not hot at all....
[Xperia Z2 Q&A, Help & Troubleshooting] ScooterG:
I have the M8 and Z2. The screen on the Z2 is brighter than my M8.
[Xperia Z2 Q&A, Help & Troubleshooting] Ryland Johnson:
A suggestion. If you have the Z1 compact as your mobile phone and desire on times a larger viewing area I would skip the Z2 and go for the Xperia Z Ultra. Prices are incredibly low now and its one hell of a viewing experience. I own the Ultra and Z2 and think the Ultra is certainly better quality in terms of materials used and construction methods. Nothing wrong with the Z2 but I was some what surprised when I received it last week. I used to own the Xperia Z and that was, despite many negative comments, a very good phone. I am unsure if the jump in size from the compact to the Z2 would be worth the financial outlay. Now the Ultra has a far greater viewing area and its less than half the price of the new Z2.

Again, just some food for thought. Your choice will be right for you I am sure of that. Good luck with what ever you purchase.

[Xperia Z2 Q&A, Help & Troubleshooting] Jejoma:
I came from the SIII and certainly don't regret it. My main concern was the size. Whilst I have got used to it, it definitely is not pocket sized. In fact, ignoring weight and thickness it is the same size as my first ever mobile, the Ericsson Hotline EH97! Ok, the screen is a bit larger :)

On the plus side, the biggest improvement is the battery. I always struggled to get one day out of the SIII but get a day and a half comfortably now.
[Xperia Z2 Q&A, Help & Troubleshooting] One Twelve:
How long do you want to shoot 1080p ? Also if you don't use stabilisation then it will last longer. But this may not always be an option you want.

Not a problem for those that shoot at half the temperature.

The thread on undervolting looks promising. There apparently is a difference with .420, maybe they will lower it further in future updates.

---------- Post added at 04:02 AM ---------- Previous post was at 04:00 AM ----------

Sounds like a fair way to draw a distinction :)

People tend to use it in a relative way though, this other device does not get so hot so Z2 gets hotter than them therefore it overheats.
[Xperia Z2 General] merfie:
Hey guys！

Some of you maybe experiencing a X-REALITY lose after BL unlock(mostly).I just found a way to fix this problem.I`m not a coder or developer,so I`ll make it easy.

1.Whatever firmware you`re on,first backup all your files from the build-in storage,the next steps will delete all of them.

2.Use flashtool`s BLU function to relock the BL (IMPORTANT!)

3.Flash the official FW17.1.A.2.69 (MUST BE!)

4.After initial boot,you get your X-reality back with locked BL

5.Now use flashtool unlock the BL again (If you boot into the system,you`ll find X-reality still functional)

6.Proceed install the recovery kernel via fastboot,then the roms you like

7.Now you have a fully functional X-reality with a custom rom.

For developers,things to be noticed:

When I flashed official FW17.1.A.2.69 under locked BL via flashtool, at the end of flash log I found an extra rewriting operation

to the TA file comparing to the FW17.1.1.A.0.402 (which there was no logs).The unlock and relock action rewrites

the TA file,so I thought it`s all about the TA file.No matter what rom or kernel you use.

Hope this would help you guys develop sth.

Tested environment:

D6503

Official FW17.1.1.A.0.402 rooted

RomAur v3.1

Official FW17.1.1.A.0.402 kernel

Doomlord kernel V09

[Xperia Z2 General] se1000:
Personally, I don't see the big deal with X-Reality. Wouldn't people want to know what the picture looks like on all devices not just their own? Maybe it's just me.
[Xperia Z2 General] lovemyram4x4:
I also don't get why so many want to have something that makes everything look wrong. I'd prefer if I could use my screen calibration tool and have applied to the system.

[Xperia Z2 General] merfie:
Obviously Sony gives us this function isn`t a waste.It`s a useful stuff viewing pics or videos.

I don`t take much attention about the color "accurate" or "reduction",afterall,it`s just a mobile phone display.

Of course you could disable it if you don`t like those colorish style,but it`s good to have this function rather than not.

No offense mate, it`s just like foods,some of you maybe like sweety things,others like hot things.;)
[Xperia Z2 General] Tea-Aholic:
Actually, I quite like X-Reality. It gives a very nice colour rendering, not crazy like AMOLED but a nice subtle colour boost and looks amazing, especially when watching YouTube videos.
[Xperia Z2 General] lynxboy:
Bump!!

Well done OP for finally figuring it out!

Tested on two occasions and this method works 100%.

Thanks again.
[Xperia Z2 General] Gitaroo:
X reality is horrible for video, cause ghosting and make things look grainy, they should just include an option for jpeg only.
[Xperia Z2 General] TheOnlyIntruder:
I don't know if I can be arsed trying to recovery X-Reality, I've just spent all afternoon configuring my phone again.

What's the easiest way to back up all my settings then so I can do this install method? Is it worth restoring my TA first?
[Xperia Z2 General] nbone:
idon't have origina FW 17.1.A.2.69 can i download ?
[Xperia Z2 General] TheOnlyIntruder:
Download the Taiwan .69 firmware found in the firmware list thread, I've done it now and it works
[Xperia Z2 General] Envious_Data:
I may try this, i dont care for bravia but xreality actualy hit me

Edit- it seems you have to use TW global LTE FTF
[Xperia Z2 General] merfie:
Yeah,u have to use TW version firmware
[Xperia Z2 General] NicotineParasite:
Bravo!!!

Hello there.. Well this is my first ever post on XDA and to be honest I just made an account to THANK YOU for your marvelous achievement regarding this Bootloader disease. I was on .314 with unlocked bootloader and custom recovery, everything was working fine untill I came to notice after a month that X-Reality is not working since I unlocked the damnloader. I have been nearly searching web for more than 10 hours yet no luck whatsoever to get back the X-Reality function. And then I found your thread and took me 2 more hours to find that Taiwan firmware and download it. Anyways to cut short, the whole process you have described works perfectly and Thankyou sooooo much once again for giving me my X-Reality back :D :good: :laugh: Now I can see .402 OTA in my notifications and gona try to update from there...
[Xperia Z2 General] sh4d1t0:
Good, I used this, I installed existenz 3.1.5 with bootloader unlocked and work it. I tried with envi-rom but doesn't work
[Xperia Z2 General] elchicodelbalcon:
Can i do this to recover locked bootloader? I unlocked it with no backup.
[Xperia Z2 General] sh4d1t0:
I unlocked it with no backup TA too.. And the answer is no, you can't recover TA DRM keys, I tried recover TA partition (I did backup before, with .55 locked), on 402 and 314 stock, and I can't recovery xreality only on custom roms
[Xperia Z2 General] numskull:
ahhh crap...... my current endeavor is a waste of time then....... oh well killed boredom i suppose
[Xperia Z2 General] HeartUnderBlade:
Where did you find the taiwan .69 firmware? The link in the firmware thread is dead :(
[Xperia Z2 General] nivet5:
the second one on the list:

http://www.mrcrab.net/androidfirmware/D6503/Sony-Xperia-Z2-D6503.html

This solution works well however you will loose Xreality again if u flash another stock FW after flashing the Taiwan FW.
[Xperia Z2 General] HeartUnderBlade:
Ahh, I see. So after flashing the TW firmware, you have to stick to using .69 or use a custom rom?

That sucks as I was hoping I could recover x-reality and flash to 4.4.4..
[Xperia Z2 General] NicotineParasite:
X-Reality lost again..

Ok so after carrying out the whole procedure I updated OTA to .402 and lost the X-reality... Then again OTA to .314 yet still no X-Reality. So I guess we just have to stick to .69 after flashing it or maybe flash a custom rom as said... I hate it though coz .69 looks like im in stone age on my XZ2 :/ I dont know when will this be resolved :( I just did a fresh flash of .314 UK unbranded but no X-Reality... :(
[Xperia Z2 General] sh4d1t0:
No works via OTA or TFT, only with custom rom with support, for example Existenz 3.0.0-3.1.5

- flash .69 (or .55) with BL Locked (x-reality should work), then unlocked, if x-reality works yet, its fine.

- flash baseband and kernel .314

- flash custom kernel with recovery (for example DoomLord V6)

- in recovery flash the custom rom with support x-reality on unlocked bootloader, without wipes (no cache wipe, no wipe dalvic cache, no wipe data).

that works for me with Existenz 3.0.0 - 3.1.5
[Xperia Z2 General] V4LKyR:
Is this only for making X-Reality work? Are the other stuff protected with DRM keys come back aswell?
[Xperia Z2 General] dkionline:
After update to 4.4.4 i had seen, Selected Super Vivid goes back to X-Reality after reboot.
[Xperia Z2 General] sh4d1t0:
Wait.. you can update to 4.4.4 and.. X-Reality works with Bootloader unlocked?

You said that supervivid don't work but x-reality works fine.. or I'm lost..
[Xperia Z2 General] bdithug:
No offence to anyone here, but why is xreality so important? I don't notice a huge difference with or without it
[Xperia Z2 General] sh4d1t0:
Better colors, contrast and more sharpness with photos and video no hd, but bad notice because this only works on Album and Video
[Xperia Z2 General] doministry:
X-Reality IS HERE on 4.4.4
[Xperia Z2 General] NicotineParasite:
Grrr.. There is no X-Reality or SuperVivid working on 4.4.4 clean install via flashtool, bootloader relocked before... Anyways im gona end up this goose chase...
[Xperia Z2 General] NicotineParasite:
Ok these issues i found on clean flash of 4.4.4 customized US:

- X-Reality & Super Vivid not working

- Speaker volume a bit low

- Low light pictures grainy as hell like as if taken with 0.3 mp

- Camera too much laggy

- Battery drain a bit, even after battery calibration

- Media apps are outdated without being updated OTA

- Personally dont like those big icons, device feels much premium in .314

So I flashed .314 UK Unbranded again and perfectly enjoying root, louder sound, etc, etc...

P.S: I have an XZ2 with lost DRM keys, bootloader relocked :)
[Xperia Z2 General] Isley_:
And with a relocked bootloader what is back?
[Xperia Z2 General] NicotineParasite:
Nothing is back, I just relocked it before while testing the BLU function of flashtool...

Btw there is a post in General Discussion claiming to get back all features that were lost with UBL through flashing some file from EXR on a deodexed rom..

[Xperia Z2 General] NicotineParasite:
Update

Ok I again flashed 4.4.4 clean with flashtool, wiped everything, and I got following results...

- X-Reality and SuperVivid not working as usual

- Battery fixed, I dont know what fixed it, getting more screen On time with less fall in battery %age

- Camera is a bit less grainy than before, but 20mpx is far better than superior auto...

- Extremely smooth UI without a single glitch or lag

- Every other option working perfect, TrackID, etc...

- I think it takes a bit time to get eyes adjusted to like the big icons, but now I feel its easier to open apps with those big icons

- Sound loudness is almost same as .314 but clear audio+ has got better and I feel that x-Loud has automatically been activated with this firmware, irrespective of it not being present in audio enhancement as an option

- No OTA updates for any system apps till now, maybe will come with some fixes in future..

Going to keep this at stock for more testing...
[Xperia Z2 General] elchicodelbalcon:
I'm having an issue on new firmware, i guess it's unlocked bootloader related.

Camera button opens camera app, but i can only take pictures touching the screen, the camera button is not responding in the camera app. I installed firmware through Emma twice, and both times i experienced the same issue...

The button works for opening the app, and when i go to 4k mode works for starting and ending video shooting, but it's not working on camera mode as shutter.
[Xperia Z2 General] sepzs:
I have relocked my phone ages ago and only things that dont work in 4.4.4 are remote play and x-reality. Do some users have issues with camera, track id and playstation app?
[Xperia Z2 General] Isley_:
OTA updates are working for you?
[Xperia Z2 General] sepzs:
It said "could not verify" when I tried update to 4.4.4 OTA but isnt that because of root? I havent checked unrooted.
[Xperia Z2 General] Isley_:
Maybe, hope unlocked BL don't are the problem for receiving OTA

updates
[Xperia Z2 General] NicotineParasite:
UL bootloader still gives OTA.. Dont know abt rooted.. And yes once UL then Xreality and remoteplay gone forever no matter what u do except backup TA partition and reflash.. No issues with camera, trackID or anything else...

- No issues with camera button on 4.4.4 with relocked bootloader DRM void
[Xperia Z2 General] NicotineParasite:
New Phone

So after all the efforts in this world playing with almost every mod, there is no cure for this disease... Therefore I finally sold my phone and got a brand new one, and man there is a huge difference... I would like to share what doesnt work after u unlock bootloader without TA backup..

- X-reality and Super Vivid gone forever (Bravia Engine)

- Camera noise is default to raw which means ur pictures will come out like taken from vga camera

- And alien invasion on ur phone :p just kidding

I got to say im amazed at the camera quality of new default factory phone, updated OTA to 4.4.4 .167, and im certainly not going to ever root or unlock BL, no matter what..

[8525, TyTN, MDA Vario II, JasJam Software Upgradin] axiom:
Has anyone successfully opened up the tytn rom for modifying? Is it possible to change the cache size the way the BA has been done. I would like to see the ability to change the default cache to 16MB or even 32MB for performance boost.
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] pof:
We are trying hard, see other posts in this forums and read the wiki...

BlueAngel has 128Mb of ram which can be used as paging pool and ramdisk... that's why after modifiying the pool size you end up with less ram (77 visible MB in helmi 1.3.2 with 16Mb pool for example).

TyTN has only 64Mb of RAM, if you take 16Mb for paging pool and 32Mb for ramdisk you'll end up with a device with 16Mb of ram... which would make it quite unusable :(

At the moment we don't have the tools nor the knowledge to make something like what mamaich has done with blueangel in the Hermes... but it's just a matter of time ;)
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] axiom:
I see. But I find the ram disk useless at anything over 12 Megs, so there would be enough room left over for additional Ram. But then that's just a personal preference.

I mean, the overall cache might not need to be 16MB, 8MB might do what 16MB does on the BA. I guess we really won't know until someone cracks it open.

In any case, I would be willing to give up ram disk for increased performance.
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] fgro:
interesting ... shouldn't the TyTN perform much better as other devices? (pointing to the CPU ... where are the 400 MhZ?) but i agree ... get lost of some MB for performance increase ... i am with you :D
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] csl1010:

I will ask him about this and get back with his answer.

hello every one...

im using my s4 for about 1 year already with no issues exept for the battery as it drains fast and not last a day..

now im facing another prob...

sometimes it gets black screen and hang when i watched on net... (youtubemobile)sample....

it will take hot for a while then it will suddenly turns to black which triggers me to restart it or remove the battery so it can turned of...

this is not happening often or everytime... but sometimes it bothers me with this issue...

is there someone also facing same problem as i do?

i hope someone can help me with this... thanks....
[Galaxy S 4 Q&A, Help & Troubleshooting] pjilka:
HI,

I purchased an unlock from a local shop. After many attempts the code was not going through.

The vendor then provided an "unfreeze code" after which I was supposed to enter the original code again. Many attempts were made, all unsuccessful. The vendor told me its an unusual situation as the codes always work and was unsure what further steps to take. (Before anyone says its a scam, I highly doubt it, as its a reputable store and they happily gave my money back)

So back to the problem, is this an issue anyone has faced before, is there a way around it? I really needed my phone as I'm going abroad tomorrow and it would've been extremely handy to have net access.

I've read in a few places people recommending going back to stock and trying, but I don't wanna risk it right now if there's no truth to it

First off, what is the difference?

Secondly, I have a d2att SGH 1747. I'm having a hell of a time finding a ROM for my phone. I want stability and upgrade-ability. I was running slim rom but that seemed confusing. Where can I find a ROM that is up to date and that I can continue updating in the future?

Isn't 4.4.2 the latest and greatest whatever?

Sorry if I'm confusing, I like desktops, not computers that one can hold in their hand. Thanks

[Galaxy Note 10.1 Accessories] Dumaru:
There was a case I saw a long time ago that seemed like it could be nice to have. As of today I started craving it and want to buy it.

It is case with a swivel hand strap on the back. This would allow for comfortable holding while drawing or carrying around. Allowing for working in Landscape or Portrait without any hand discomfort.

I had put the case on a wish list on Amazon, but I have since deleted it. Does anyone know of one? I am not having any luck finding on today.
[Galaxy Note 10.1 Accessories] rtan73:
I recently switched from a Note 10.1 to a Windows tablet, but also use it for drawing. Currently I am using a standard leather case with something called "hand-e-holder" attached. I got mine on Ebay, but Amazon sells it also. There is a pad(sort of like velcro) that attaches to the case or tablet. The handle then sticks to the pad, so the handle can be removed it needed. Whats also good is that it is very comfortable, and does not freely rotate when trying to draw.

I looked into a couple of other "handles" that either stick on or wrap around the device, but I think will fit your needs the best. When searching Amazon for the Hand-e-holder, if you look at the related products you'll find similar handles.

I tried cases that rotate but there's no resistance to it tends to rotate in every direction when trying to draw.

Hope that helps. Us artists, got to stick together.
