[Q] [LOLLIPOP .690] Backlight not turning off - Xperia Z2 Q&A, Help & Troubleshooting

Backlight won't turn off when phone is locked.
Worked fine before update.
Workaround:
Settings->Display
Toggle "Adaptive Brightness" Off and On
Lock phone.
Why is this happening?

try reflashing a FTF without data wipe
if it continues, flash a FTF with data wipe, and if it continues again then contact sony repair
BUT FIRST make sure to uninstall all mods first and dont reinstall untill youve done testing
sometimes mods can cause issues if any

It is stock lollipop, no root either... :/
But i will try to repair it with pc companion.

sometimes when i make the screen timeout for 30minutes, it will also turn off by itself and restart back by itself. sometimes it goes off and no reboot back.
i have search on XDA and found that few problems like mine.
i try few solution like take out the battery, uninstall apps which maybe make my phone turn off.
i also reflash my phone to 2.3.3 and also reflash back to 2.3.4. it just goes the same. my warranty have void as i have unlock my bootloader.
i just dont root my phone yet as i think rooting my phone doesnt help this problem.

Does it make any difference if you start the phone with the charger plugged into it?
...or even without the SIM card or SD card? Any difference at all?

I bought the phone over from bobo. And yes it does make a difference.
This problem does not occur whenever the phone is plugged in. However while running on battery, if I leave it be and once it goes into standby, it would not turn on again.
Seems to me it went into sleep of death.
At the moment, I have no idea how to fix it. But I've found a workaround by keeping the CPU on when the display is off by using wake_lock. However this workaround is a little battery consuming.

bro i have this problem before, what im doing before was playing music on mute for it not to turn off NOT until 0.62 FW came out and the problem was solved, it doesnt turn off on stock 0.62 fw and stock 2.3.4 but the screen when locked automatically turns on and off multiple times, its annoying..really so i decided to unlock my bootloader, flashed rooted 0.62 FW from here http://forum.xda-developers.com/showthread.php?t=1440161, turning on and off phone and screen solved, flashed its respective ROM http://forum.xda-developers.com/showthread.php?t=1373435, and now my phone is so stable and having no more problem.
i think the only problem i noticed just now is the back button (its not really a button) and the option button's light is turning off and on while screen is on. but thats better than your phone turns on and off or your screen.
i hope this helps.

I've done this too. Flashed the same kernel, and the same ROM as you did. But the problem still prevails in my phone. I still have to keep control of wake_lock to prevent CPU from sleeping while the display is off.
Btw, when I flashed the kernel, under my "About" in the settings, it still says .58 instead of .62.

you mean in the Settings>About Phone> in the build number it should have HYBROM V9 by boof not the kernel name like .58 or .62 if you flashed the kernel and rom correctly.
disable lockscreen
Try to disable your lockscreen in the settings menu. Maybe that helps
My phone have the very same problem.
Any good new?
I've tried the factory restore. Didn't solve the problem.
so....no solutions yet!!??!

MiniCM10-4.0.1 Can't install any apps

Hello,
since i've updated my firmware to MiniCM10-4.0.1 i can't install any apps.
The only thing is coming when i'm trying to install something is: 'Application not installed'. I already tried a factory reset but it didn't help and the option 'unknown sources' is activated..
Everything works except of that.
My phone is a Sony Ericsson Xperia Mini Pro.
please help me..
Hi
Did you wipe /system, /data and /cache through cwm before installing?
Did you try a full reinstall with kernel and rom?
Do you have the newest jb kernel from nAa?
Can you install apps from the sdcard with the apk?
Answer these and we could propably help
black screen
Ok, i solved the problem. Just added some apps to the rom of the firmware und reinstalled it. And yes, it was the actual firmware and kernel. There was no PlayStore when I installed it for the first time and only some .apk are working.
Now i've got another problem, sometimes the screen stays black after pushing a button. What means sometimes, it happens about every hour, or twice a hour, or four times a hour. It's so annoying, because then i have to take out the battery und put it back in the device again.
I don't know what to do about it, i tried to change the cpuspeed and turned off the automatical screenbrightness, but with no effect.
If you'd read the miniCM10 thread, then you'd know that
this is a known bug.
You dont have to pull out the battery,
when I got this problem I have to push
the power button few times and then
the screen lights up.
doesn't work, the phone just restarts.

[Q] Bluetooth Problem in Xperia Neo L

Hello Freinds,
I have the major issue of bluetooth with my neo L.
Problem occured when I try to turn bluetooth ON, It force the device to restart and enters in bootloop.
I have stock rom and stock kernel and not-rooted.
Xperia Support suggest me to do factory reset the device.
I did factory reset and it works well after reset.
But after 2 weeks, the same problem happened again.
So, My point is that I have to reset it again and I have to configure my phone as per my use again and again..
It is very irritating.
Please give me any other option to solve the problem or fix it because i dont want to reset my phone, and it took 2-3 days to reconfigure my phone.
Please give me another solution as soon as possible,
Thanks,
Raaj
Yuppeee!!!!! Problem Solved.......!!

Xperia Z2 stuck in bootloop with generic android / cyanogen runs without problems..

Hi, I have a strange problem with my Xerpia Z2..
After flashing a cyanogen mod to test it out.. it`s not possible for me to get a working generic Android system anymore.
The smartphone stuck in a caint of "bootloop" or, if it start android at last, it reboots after a short while automaticly.
The bootloop is like this:
Screen: Shows 10 sec. sony-logo -> than 2 sec. black screen -> than 5 sec. sony-logo -> than it starts from beginning..
The bootloop-lenght varied until it starts finally into android.. sometime it doesn`t come to that point, and it reboots for a very long period (until I get annoyed and shut it down)
I have trying the following things to solve that issue:
- Flashing several stockroms wirh flashtool (D6503_17.1.2.A.0.314_Generic DE.ftf / D6503_23.0.1.A.0.167_Customized DE.ftf)
- trying to reset the hole phone with the xperia "emma" tool
- trying to reset the hole phone with the pc companion software
.. in my opinion, the problem could be find in the bootloader/recovery.. I don`t think it`s a hardware issue, because cyanogen mod is still runs without problems. Maybe some cyanogen remains are still leftover in the bootloader, that don`t work with generic android versions.. that`s what I can imagine. (but i`m not an expert
I don`t get why flashing the phone doesn`t solve the issue., it almost seems that the flash process don`t touch the bootloader, to overwrite it with stock parameters (?) or does not fix that area which is responsible for that issue..
Phone status at this time:
Not root - not unlocked - no backup of TA - DRM Keys (The guy that I bought that phone from, saddly doesn`t do a backup /
Before you flash the stock rom, are you clearing the Dalvik cache?
Whenever I've been through instructions on flashing roms, that always seems to be a step, but I didn't see you mention doing that before flashing.
