[Nexus 4 Q&A, Help & Troubleshooting] alphadog32:
Whenever I flash a custom ROM, I notice the phone's performance degrade. Is this only me?
[Nexus 4 Q&A, Help & Troubleshooting] captivated1971:
i think it all depends on software and what tweaks you have enabled as to how well it will perform.
[Nexus 4 Q&A, Help & Troubleshooting] alphadog32:
On Stock CyanogenMOD or AOKP, the phone becomes slower. But with Stock ROMs - Linaro Built it becomes faster.
[Nexus 4 Q&A, Help & Troubleshooting] Soul reaper:
i have also encounterd some adrops in performance while using custom roms.....maybe bcoz of more features ...stock rom is more stable and simple that makes it perfct for devices as its in its native environmnt.So i assume stock is faster than custom but at same time boring :(
[Nexus 4 Q&A, Help & Troubleshooting] hbararaya:
You can try who is the most faster for you :D
[Nexus 4 Q&A, Help & Troubleshooting] scottx .:
I'd think a basic aosp build with a good kernel would be faster than stock. (Even though aosp is technically stock)
[Nexus 4 Q&A, Help & Troubleshooting] asasione:
I've also noticed this, I've tried most custom ROMS and stock is hard to beat in performance although it lacks options
[Nexus 4 Q&A, Help & Troubleshooting] gee2012:
So run the latest stock rom with a custom kernel and some mods and you`ll have the best of both worlds ;)
[Nexus 4 Q&A, Help & Troubleshooting] molesarecoming:
its the same. but booting into stock is indeed always something special because you're fullwiping into a clean system and that can be felt. the more apps you install, things that hog in the background mostly, you start to notice slight differences but that you get on stock, too. android is much like windows in that regard, it degrades in time. i had stock android for a long time on my nex7, at some point it got so laggy i had to start from scratch. anyway, technically roms are faster, but i doubt it matters in daily use.
[Nexus 4 Q&A, Help & Troubleshooting] gee2012:
Very true, it clutters up pretty fast.
[Nexus 4 Q&A, Help & Troubleshooting] Cantacid:
Try Greenify, its a brilliant piece of software, well thought, stable and helps manage those stuck up softwares, including facebook!
[Nexus 4 Q&A, Help & Troubleshooting] cgulliver:
Exactly. I have stock with all the Faux123 kernel mods running and my N4 is hummin.

Hi there, thanx again and again for your eccellent work!

I got into a heavy rain the other day and when I picked my toy from the waterproof compartement of my backback it was completely soaked! :shock:

And after a lot of fancy flashing and ringing, that I could only stop by hard resetting it, it went dead altogether. :cry:

Now it dried up again I'm kind of surprised to find it actually works again only it obviously lost all it's memory. And after honestly following every single thread and reading every post, I give up and finally post a question.

Used to be Rom 3.14 and Radio Stack 3.16.xx (I don't remember) all german O2. Bootloader 5.15.

My problem is, that whenever I try to get a rom image (the newest version of the german Programm A - which is an .nbf file after extracting)

onto my SD card (Scandisk 256 MB), it will stop immediately after I hit the OK Button in the XDArite App, outputting 'Successfully copied image of 65538 blocks'. Obviously it didn't because I figure it would need quite some minutes to copy 30 MB of data onto the SD card. And the bootloader doesn't recognise anything on the card.

In the beginning I could read the card under XP and could save all my data, but now after trying XDArit a couple of times I can't read the card anymore under XP (it still shows up as a removable Harddisk in the explorer but Windows can't even format the card anymore). :?

Does anybody have any suggestions on that matter, I would very much appreciate that!! :D
[MDA, XDA, 1010 Software Upgrading] Peter Poelman:
Have you recently downloaded the new version of XDArit? If so: be advised that there's now two other people that seem to be having problems they did not have on the first version. So you could try the old version, still around at http://xda-developers.com/XDArit/old

You may to also read the page for the warning on the old version.

(We created /old/ subdirs for all our software, by the way)

XDArit needs a rehaul, and we know it. We currently don't have much time, and this would be a good project for a coding volunteer. We have plenty of good ideas as to what should be in there.
[MDA, XDA, 1010 Software Upgrading] BORIS:
Same problem, It doesn't actualy write to the card ?
[MDA, XDA, 1010 Software Upgrading] Guest:
Same problem... this is how I fixed it... the old version may work better for you (but I've never used it). http://www.xda-developers.com/forum/viewtopic.php?t=1451
[MDA, XDA, 1010 Software Upgrading] BORIS:
Thanks for your reply, Ive requested assistance from the author of the post you suggest, but i`ll ask you the same question. Any chance of the recompiled file so that I could try it.

Many thanks in advance BORIS.

Anyone pick one of these up? They are only at t mobile they are 25 bucks but its the most perfect case IMO its just like the diztronic style just all black
[Nexus 4 Q&A, Help & Troubleshooting] speedygonzo:
Saw those today at my local T-Mobile store. Might pick one up tomorrow. Kinda pricey though.
[Nexus 4 Q&A, Help & Troubleshooting] NLPUNITED:
Why not get a Diztronic or Cruzerlite cheaper with better looks ?
[Nexus 4 Q&A, Help & Troubleshooting] FatalityBoyZahy:
It's just like any other TPU Case... now if it was a D3O case, I would quickly shell out $25.

[Nexus 4 Q&A, Help & Troubleshooting] ridearoundsolo:
Mines good its just plain black no logos, buttons work fine here
[Nexus 4 Q&A, Help & Troubleshooting] ciproxr:
im a little late here but i bought this case a while ago and i really liked it, i liked the feel and design better than the diztronic, where the screen part is its not as raised and wide like the diztronic is.

With that being said im using the diztronic casue of the prize difference and also cause the buttons weren't that easy to press on the tmobile case, was not horrible but not great.
[Nexus 4 Q&A, Help & Troubleshooting] aanonymoushuman:
I have this case have been using for 5 wks now, pretty good design although the buttons are sometimes hard to press, that's why I use slide to unlock. I dropped my nexus face down on solid concrete from about 4ft high with this case on, not a single scratch(;
[Nexus 4 Q&A, Help & Troubleshooting] scream4cheese:
$25?! Sheesh.
[LG Thrill 4G] ddaddy11:
I've been using cyanogenmod 7 and the call quality was problematic as was my bluetooth. I recently switched to Thrill Seeker 3.1 and everything is working great except I can't access the settings for Google Voice voicemail, even though I picked Google Voice for my voicemail, it still goes to the carrier. In other words, I have to call in to get my voicemail as opposed to having it in my Google Voice. I haven't done much to the programs, but I have deleted all of the 3D programs, games and Gulliver's Travel. Will that have affected it?

Thanks.

[Xperia Z General] Mr.Dadulka:
There is actually not much to go lower - more or less set according to your suggestion - first steps at 800 mA.

Also stable without any issue. Seems I can recommend it to others. I cannot evaluate the battery as I run it for a short time and had some hidden wakelock by Google but seems to be a little bit better than stock setting.
[Xperia Z General] grievous2004:
Thank you for the settings! I've applied them and had no freezes or reboots in 5 hours.

Battery life seems really improved (95% after 5 hours with 30 minutes screen on) undervolting and using the app greenify (my phone sleeps like a baby!). I'll test deeper uv in the next days ;)
[Xperia Z General] ssj_jaypee:
wow thats impressive!

Trying 1836mhz @1200mV.... the Problem there is the Phone Already Throttles Down the 3 other Cores to 1512 when the battery hits 27°C xD Lucky it's water proof!

Edit: Crap 1200 doesn't work! made 4 Antutu benches with CoolTool overlay and Trepn profiler logging no PRoblem! But doing solely Antutu it crashes! had to raise it to 1225mV

@BoneMo with 20°C WaterTemperature, nope.

Hi,

Just trying to figure out this under volting, I'm using Trickster Mod on Doomkernal V8 - I've set my Min frequency to 19200 and adjusted my CPU voltage 25000 across the board, except my Max speed which I left at stock. It appears to be running ok so I set it at boot to load these profiles.

I would like to know is there a guide for setting everything up "properly" in Trickster Mod for Xperia Z ? Is there anything else I should do/try ? I'm unsure how some users have a different set of figures between tuning apps, is there some way to convert ?
[Xperia Z General] xNAPx:
which stable voltages are advised for every frequency over stock max 1,5ghz? i.e 1,6 ghz - 1,7 ghz and so on...
[Xperia Z General] kennycol:
weird behavior

Hi everyone, was helping you could give me a hand with a doubt, this morning afer waking up i saw the attached image behavior. It started drawing considerably energy while been idle (i was sleeping), and then it drained almost 10% of energy crazy fast, what do you guys think?

All i did was set up an alarm, also there was a (sony native calendar) remainder for today which i suspect may be the culprit, signal is kinda bad so that too could be the cause but i havent seen this behavior last couple of days with the same crappy signal.

No theories regarding the 6:40, maybe the system looking for updates as that was approx the time when i got the phone into the signal amplifier.

Thanks for your input

[Xperia Z General] xNAPx:
why do you need all those apps to overclock? isn't kernel tuner sufficient to do everything?
[Xperia Z General] Haldi4803:
i absolutly hate Kernel Tuner!

A: because settings will be applied right at start, even when you set 1.99ghz and smartphone crashes! at next boot you have 1.99ghz set!

B: because there is no freakin way you can control CPU clock with THIS sliders!

But it's the only app (afaik) that forces 4 cores always active (MP_decision in Faux does not) for overclocking. if your core is in sleep it most like wont apply the new speed! and if i goes into sleep its gonna quit OC/UC anyway.
[Xperia Z General] killgrozrism:

I am more interested @ which voltages cpu is stable @ OC frequencies.

I don't like kernel tuner due the fact that cores stay not active for strange reasons, at least on my device I encountered this issue

So which one apps you prefer to set cpu freq (just to enable 192MHz), cores governors, and uv..

I really love set cpu, but it cannot set voltages and just set cpu0 governors

[Xperia Z General] Haldi4803:
Jup, if you disable, restore settings on boot, thats fine. But how do you manage to change CPU frequency ? ^^ As you can see in this picture you have a 2mm bar for sliding from 192 to 1944 !

It's tricky sometimes, you have to press both at the same time, press one a little early and it doesnt work.

And i made a little update on this Post avout OC'ing.

I just tried installing the DoomKernel for the first time and my phone wouldn't boot, it got to the splash screen, screen went blank and then a few seconds later rebooted. It stayed in this cycle until I entered Clockworkmod and recovered.

I am running Cyanogenmod 10.1.3-yuga. Is DoomKernal incompatable with this ROM? I've never changed the kernel before so this might just be common knowledge amongst you guys.

If it's not compatable, is there an undervolting kernel that is?
[Xperia Z General] aembleton:
For anyone else that has this problem, it might be work trying Cyanogenmod 10.2 from the nightlies. I'm running that with meow kernel now and all is fine.
[Xperia Z General] mankent7:
DoomKernel is stock kernel only for stock rom. if u r runing cm's rom should use other kernel otherwise u get boot loop.
[Xperia Z General] JediRAMA:
I changed only

384 - 700

phone sleeping very well on this.
[Xperia Z General] Haldi4803:
so.... anyone with stock 4.3 yet ? :)
[Xperia Z General] beni8978:
I got 14hours standby with 4hours and 45minutes of SOT with 4.3 stock.

Great battery life,i don't wanna buy the Z1 anymore because my Z became stable near like the HTC One :)
[Xperia Z General] sadebash:
It seems really great. Have you done any undervolting/tweaks?
[Xperia Z General] beni8978:
Apsolutely nothing,pure sony stock 4.3 :thumbup:
[Xperia Z General] Haldi4803:
So these are from Beanstalk 4.4 Sync Activated, Mobile Data Activated, 2x Email Exchange Push, Google Backups and all.

And then i had to switch to Prepaid:

Mobile Data always deactivated, Beanstalk settings Deactivate Data on Screen off:

Standby:

And then some Browsing via Chrome:

P.S the Always Active is a bug !
