Hi There,
Shortly after updating my Nexus 4 to 4.2.2 OTA today the screen went blank and I've been unable to get it to function correctly again.
The phone is still showing some signs of life, I am getting notification LEDs and I am unable to unlock the phone with facial recognition even though the screen remains blank - I can tell from the vibration and the LED stopping that it has unlocked. Pressing the power button to lock it starts the notification LED again.
I have tried a hard boot (Volume Down + Power) and the screen did come on to display the google logo followed by the X but as soon as they had been shown it returned to a blank screen.
Does anybody have any ideas of what this could be or how to solve it or should I contact Google in regards to this issue?
Thanks in advance for any help
seems like the OTA update has corrupted somewhere. You should reboot into bootloader and use fastboot to flash the stock 4.2.2
Is there anything else worth trying before doing that? I wouldn't have a clue where to start as this is my first android device
Ok so I got it working but did lose all my data. If anyone else comes across this issue I had to boot into recovery mode and do a full wipe/factory reset. The first time i did this the phone started up with no problems but during configuration when I entered my Google account the blank screen strangely returned so I again did a full wipe in recovery mode, skipped the 'set-up google account' step and then entered it manually later in settings once the device had started up.
No idea what caused this and if its a bug in 4.2.2 or an issue with some settings in my google account that are being backed up and restored to the phone but either way I had no problems until 4.2.2 update installed and the issue occuring even after first data wipe rules out any third party apps being the cause.
I had a similar problem after updaing that the screen stay blank and it wo'nt unlock
As soon as i disable the bluetooth the problem solved.
It's happened when i paired it with my pc
I have been having a problem with my note 4. When ever the phone is powered down and powered back up it reboots normally. I see my lock screen and everything is fine. The problem is when the phone locks either by the power button or just by screen time out. It stays a black screen even though i can swipe my my finger and hear it being unlocked. They only way to fix it is to take the battery out and reboot it then everything is good until i lock it again. Any help would be appreciated thank you.
Sorry me again just wanted to ask another question. I rooted my note 4 after this problem started happening. I used cf-auto root so from what information i have seen im still running stock recovery justed rooted. I was wondering can i flash a Samsung software upgrade without any problems. My problem with the black screen started after an software update so i wondering if i could flash and reinstall the update to see if that fixes my problem. Once again thanks in advance for your help im just trying to save my phone and hoping its not a hardware issue.
Hey everyone,
So my phone died and then I got it charged and turned on and it booted up to the encryption lock screen where it says to start up your device, enter your pin. So I enter my pin and then its says, "verified" and then "starting android". and then a padlock appears on the screen, it opens, and there's like a load up circle going around it. At first, I let the phone sit to see if it would do anything but after an hour, I figured something is wrong. I dont know why this happened, I think I might have accidentally turned on the secondary encryption, but this really sucks, I don't want to have to factory reset and lose all my pictures and data. I can boot into recovery mode but sometimes when i turn it on it shows a screen that says installing update and has like a google ring looking thing that should be spinning around but it looks like its glitching out, after that screen it will go to a no command screen, and then it will eventually reach recovery mode. I really hope someone can help or knows what is going on because, I really dont want to lose all my stuff.
Thanks for your time
I tried posting link but im new, if you look up s7 edge frozen encryption, its the first link , another person describes the same issue.
I had this issue. In recovery, tell it to clear the delvic cache. Then try a reboot.
It too a few attempts before the phone would not boot directly into recovery. But once i got it to do a normal boot, it started normally.
Then after it's running, back it all up, boot into recovery, and do a system restore.
Hi I wonder if anyone can help me. I restarted my phone, it asks for my pin which I enter correctly. It then gets stuck on spinning padlock. I've tried a soft reset (I think that's what it's called, holding down power and volume keys). It restarts, I enter pin, it says starting android then gets stuck again. I'm not very tech minded (typical girl). Can anyone help. I'd rather not lose all my photos and apps. Thank you so so much in advance. Toni x
I am facing the same issue, but with a Samsung Galaxy S8.
- Safe mode: doesn't boot
- Recovery mode: works, clear cache doesn't solve the problem.
So since nothing worked to make it work (except the Factory Reset, but I didn't tried this option), I decided to wait in the padlock screen. After 3 hours the phone started.
I guess that the phone is decrypting some big file during startup. Indeed, some days before before this problem happens, I downloaded some big files via torrent (~2-4 GB video files).
I'll delete these files and make some tests to understand the source of this problem.
Have same issue after recent update, tried clearing cache and safe mode but didn't help, been on padlock for about 10 hours now, any solutions/experiences?
ps: on stock rom with stock recovery, no root or anything of that sort at all.
Have exactly the same issue..Please help

Hi All,
I installed DP2 today via OTA (fully stock, locked bootloader) on restart I have to enter my password to boot/unecrypt. When the phone is started I have to type in the password as fingerprint won't work after restarting.... at this point the screen goes blank and drops me back to the lock screen. I know it is the correct password as there is no error and it is the same password I booted with.
Is anyone else experiencing this? I think it will be a factory reset for me! (
Thanks Andi
I reset my phone and am very pleased that the google backup is so much more fully featured these days.
I think that the issue may have been caused by my companies MDM software as there was an alert / notification I could not read/action.
All working nicely on dp2 now
Hi y'all! I have a serious issue I can't, for the love of me, resolve.
I installed the "Insert Custom Text" mod onto my rooted Android 7.0 Honor 8 phone and it broke my display so my phone boots to a black lock screen and all I can do is power off or restart. Restarting in safe mode yields same result. I can't factory reset either. I can't access my file system through my laptop either. Does anyone know how to go about fixing this, please?
