[Q] c6833 Firmware .532 has a backlight problem. Anyone? - Sony Xperia Z Ultra

I am using C6833 HK version with firmware .532
The device is unlocked and not rooted
Here is my Youtube URL (can't use link yet)

It also has SOD problem. The screen suddenly turns off and does not turn on again. You have to reboot by pressing power + volume up
+ The auto-brightness is not working either. You have to go to settings-display to manually disable and enable it back to make the auto-brightness work again.

This occured to me once since updating to .532
The backlight was not working so the screen was really dark, I had to use the hard reset button to fix it, hasn't happened again though.
And my auto brightness is also a bit flaky, doesn't seem to be responding to changes in light

S3 Lock Screen Issues - Getting Stuck

weird and terribly disappointing. Once in atleast 15 unlocks, when I press the power/wake button, screen just doesnt respond. I try to swipe, but no response. But when I press wake button to turn off screen and press it again, theres no issues. This happens only during unlocking screen. Did anyone face this issue?
rest all is good..no lag..once unlocked phone works perfectly...no lag..no getting stuck..again, let me tell u this issue happens once in 15-20 lock/unlocks.
I think I have the same issue as you, but in case I don't I will post what I am seeing on my device.
In about the same frequency, say once in every 15 unlocks from phone sleeping, the screen will come on but will be completely unresponsive. Doesn't matter if it is swipe unlock or pin code etc, there is no response to touch input on the screen. In fact, I think the screen is just frozen or the operating system is causing the lock screen to hang.
If the lock screen is hanging, pressing power will:
(a) sometimes make the phone sleep again
(b) make the phone screen kind of glitch/blip and then it takes input again
(c) does nothing and the screen remains on and hung/frozen
Occasionally mashing both the volume key and power key will help fix it, but usually if it is completely stuck I have to do a hard reset (holding HOME+VOL UP+POWER and then selecting reboot from the menu).
Now - I think this could be an app, but not sure.
When I first got the phone, set it up with my Google account etc, it went ahead and downloaded ALL the apps I had installed on my previous phone (HTC Sensation running Android ICS). So if it is an app, it is having issues with this phone, not the OS, imo.
I uninstalled all those automatically downloaded apps, and used the phone for a bit without my normal stuff installed. Then started installing apps singularly.
I think it is either Facebook or Alarm Clock Xtreme. The latter makes more sense given it would be polling the system to find out when to go off, so it is doing more in the background I would expect than Facebook or any other non-system app.
Other apps I have installed/running:
Swiftkey X
3G watchdog
Dolphin Browser HD
ES File Explorer
Winamp (locks without this running or running at all in lock screen mode, so that is not the issue)
Real Calc
Google Drive
Facebook
Alarm Clock Xtreme
It is quite frustrating for a brand new phone to have these issues. Not sure if it is hardware related, and if it is, I want to find out soon so I can take it back to carrier within their 28day device swap RMA period.
Thoughts?
So others may try to help or identify the possible cause / fix .......
What is your firmware version?
Are you rooted, custom ROMs or Mods etc?
Stock ROM,Baseband : XXLE8. Build No :XXALE9.
But my screen responds after i press wake button again. You are right seems to be issue with the app. i will just compare your apps and below are the ones which are common between us.
Facebook
3G watchdog
Dolphin Browser HD --i never use
Google Drive
a fix that worked for me
Steps to the solution that worked for me (so far) were to uninstall:
1. Alarm Clock Extreme (no noticeable result but I wasn't needing that application anyway)
2. I had WIFI Fixer installed because of the problems I experienced with the WIFI connectivity on my Galaxy S3.
I disabled that application and problems seemed to go away for a time, but every so in a while they resurfaced. Much less often than before, though.
I was still stuck with my WIFI problem anyway, so I looked into solutions for that problem and since I could not find a workable solution I uninstalled Wifi Fixer and started tweaking my WIFI settings.
While doing that I noticed that disabling "Network Notification" under the Settings -> WIFI -> Advanced tab fixed both my problems.
Now I can't be 100% sure this solution works for all, but I am pretty sure the application that created the problem was "WIFI Fixer".
It's been more than 4 hours now without the "disabled unlock screen from hell", and I’m very happy.
LOOOL
Actually...
My WIFI problem was not solved.... but I found a solution on another forum , which you can read below:
I dialed *#0011# then pressed menu button, then selected WIFI, and pressed the button to turn off the "WIFI power save mode". Hit back until I was back in the homescreen. WIFI has worked to my satisfaction ever since.
This is not a solution, this is a work-around....
It will remove the standby wifi.... My phone was at 0% battery in one night... But actually yes, the phone doesn't hang up when unlocking.
Someone who had replaced the phone could tell me if the problem is solved with a new one ?

This looks like a bug from wifi, i had the same problem and i found a fix:
On the dialer type: *#0011#
Then press menu -> wifi, there is a button ON ( power saving or something ), change it to OFF.
let me know if it solves ur problem
It worked!!

This worked for me!!! Thank you!! I was about to take a hammer to this phone! :good:
I seem to have another problem. When unlocking the phone the screen turns on in a quite ok amount of time, but then when I touch it immediatelly after it turns on it doesn't react to touch. This moment when touch is not working is getting longer and longer depending on how long the system is running, anybody else sees this?

Not sure what ROM and kernel you are using, but at a big guess, try reflash another kernel or with less aggressive settings.

[Q] (Q)Gyro sensor stop working

The Gyro sensor stop working on my Xperia S with .75 stock rom, the screen will not be rotate at all, I have tried the master reset, still doesn't work. If I use the compass, the screen goes blank and then restart. Please advise
Correct me if I'm wrong, but the phone does not use the Gyro in order to rotate screen. It uses the accelerometer...
And there must be an option to enable/disable it from the settings (I do not have the phone right now to be sure).
You turn it off in option, and you above me are correct.
Sent from my LT26i using XDA
The problem is the auto rotation option is already enabled, the accelerometer is control the screen rotation, while the gyro sensor detects the movement of the phone, they are both not working for some reasons, if I restart the phone, it might work for a while and then stop working again.
Use this code in dialer and test them

It says function not built in!!
Not built in?!?
Maybe you should head to Sony Service!
reflashed
NO the gyro+ accelerometer are built in the phone definately
since is work in my one !
Did you dropped, hitted?
try to re flash using PCC if not 99% your phone will have 2-3 weeks holiday from you in Sony repair center because it the hardware problem. guess
Tried to restore it to the factory setting, reflashed through PCC. It is still the same. It might work for couple of minutes or otherwise hours, but then it starts not working again. It is really annoying! The funny bit is the display would just stay horizontally, no matter which way I hold the phone while the "auto rotation" option is enabled.
Probably send to the service centre is the only way, as my screen has the yellowish problem too. I need to get it fix anyway.

AUTO ROTATION PROBLEM:
Tried on xperia p
TRY THIS AT YOUR OWN RISK OR ASK PROFESSIONAL !!!
I solved it by opening the phone and then tapping the gyro sensor IC a bit. After that auto rotate started working and no problem uptill now.

Can't acces screen?

Hey, i have a problem with my phone not being able to be waked up with pressing the hard key or dubbletapping on the screen. When i press the power button to wake it up, the soft-keys lights up, but not the screen. It stays completely dark. The only way for me to access my phone, is to force shutdown by holding down the powerbutton. It started like 2 days ago, but i thought; that won't be a problem. I'll just force a shutdown when it happens. But today i revived a phone call, but i wasn't able to pick up the phone, because my screen turned dark. Again softkeys turned on but not the screen.
Using a Oneplus One, with the latest CM12.1 nightlies (That might be the problem), rooted, twrp, and a bunch of xposed modules.

Or maybe it is Xposed that causing the issue. Are you using the latest Xposed version (v75)? If yes, try to uninstall Xposed through recovery and check whether the issue still persists. Otherwise update to the latest Xposed version and check again.
If Xposed isn't the culprit, revert back to an older nightly version of CM12.1 which is known to work without issues and wait for a new nightly or - even better - a stable release.
Thread moved to proper forum
Problem solved
It seems like it was the xposed module "YouTube background play" that caused the problem. Simply disabling it, made my phone work as normal. Still don't see how a module for YouTube can cause so much damage..
Thanks for the help

Odd Galaxy s6 Edge Issues

Hi everyone
I've been having some odd issues start occurring around a month ago on my Galaxy S6 Edge 64GB (G925W8):
1. Auto brightness turned on - Screen flickers between low and high backlight very quickly, mainly when outdoors.
2. Home button stopped working completely for 8 days (fingerprint scanner on the button still worked) but temporarily came back last night but is now again unresponsive to presses.
3. Power button intermittently works, 75% of the time I connect to charger it will start to work again for a short time.
Any ideas why these issues would have started occurring and are there any fixes? The only thing I can think of is that I flashed 6.0.1 (6.0.1 EastLink on to 5.1.1 Rogers) on to the phone but I've re-flashed with no luck.
Cheers
1. its the outdoor mode that makes your screen flicker. turn it on manually and try to change brightness, it will be the same

You're right, when I change the brightness on the slider, the screen doesn't change at all. This is the same even if I'm indoors.
Any ideas how to disable outdoor mode? I cannot find a setting for it anywhere.
Turns out the home button was "worn out" when I took it in for repair for a phone around a year old!
Unfortunately, a broken home button also means the screen and sensors need to be replaced too but luckily I managed to get the repair done for free by Samsung.

Unlocking the phone is a hassle sometimes...

Hello, Everyone.
It's my first time posting here. I just received my phone yesterday with 64gb/3gb MTK variant. I have been testing it out and noticed that unlocking the phone is a bit buggy or is there a setting i can change? Here is the problem: When i unlock the phone via power button it turns on and after a split second the screen turns off. And if i try to unlock it again via power button it won't turn on. If i try to unlock it via fingerprint it turns on and everything is fine again. Is this a bug or a feature i can turn off?
Thank you.

Hi,
I don't believe that to be the default behavior when pressing the power button.
What is the version of your ROM?

This happens after you leave the phone for a bit right? Not after you manually turn off the screen. I think what is happening is the moment you try to unlock it, the screen is not actually locked but the brightness is just way too low. This phone when left untouched has a two stage brightness dim
1. The brightness when you immediately stop using it
2. A lower brightness which comes 15 seconds after you stop using it and then it actually locks
The latest global developer ROM does not have this problem as they increased the second stage dim brightness so that users are not fooled into thinking that the screen has been locked
