Hi all,
As I woke up this morning and booted my beloved G4 the screen went fully unresponsive. It runs boot normally apparently, but no touch is being registered after boot finishes at my normal unlock screen. No vibration even. No pattern swipe, no camera app, no emergency call. Battery went in and out several times, but it boots nicely again and I`m back where I was. No loop, it boots only once. Double-tap on screen functions perfectly tho, no prob there.
I tried a hard reset w back buttons but it captures a nice screenshot for me. (Funny story: when I pressed just the up and down volumes it boots normally as well.)
USB to PC doesn`t recognize cause unresponsive and locked. Fully stock, no mods, root or else...
I bought it last October on Amazon unlocked international version so it must`ve spend some time on a shelf probably.
Any ideas?

So I bought my wife a new Tab Pro 10.1 model. It started doing this immediately out of the box. Screen works fine for a while. After you lock the device and the screen shuts off, it won't come back on. When you unlock the device everything works, except the screen stays black. Digitizer works, you can swipe to unlock, hear unlock sounds, and even the backlight keys work. Screen just stays off. If you hold power and reboot, the samsung logo shows up and all is good again, until you lock the device. I performed a factory reset, and even played with all settings I could think of. I don't want to flash a custom ROM to see if that's it, as I might need to send it in. Any ideas?

Problems with my Samsung Galaxy Tab S 8.4 SM-T705:
1st: October 2014
2 weeks after buying, my tablet's battery drained overnight from 45% to zero. Next morning, I turned my tab on after charging to find out that the Tab starts but without any Samsung GAlaxy Tab S logo or Samsung Logo and the Screen has turned green, rendering it difficult to read in auto brightness mode or low brightness mode.
I restarted the device 2-3times and the device started working normally. This was my 1st device restart. I never used to power off the device before.
In 1st 6months, this greenish display problem n logo problem occured 2-3times, and i ignored it, because, it used to get resolved by itself with restart and I had no service centre in and around 50km to my work place.
2nd: January 2014
My device all of a sudden stopped working.. actually hanged.. I managed to turn it off but failed to restart it.
Later I realised that the device has restarted, but the screen was not responding when the screen blinked for a moment with the opening of book cover.. and the back cover of device was warm..
Googling taught me the way to access recovery screen n I opened recovery mode with "power+vol down+home key" and pressing vol down in recovery screen to restart tab.. again the tab started working fine..
3rd: Lollipop update: May 2015
I did Lollipop update. The device was smooth to operate at first. But gradually, i noticed that unlocking the tab failed to light up the display everytime, just the soft keys lighted up. But one day, the device freezed with no response from touch screen. I was unable to switch off the device also.. I had to drain the battery by playing music using S voice to turn the device off. "power+vol down+home key" too was not working.
On googling, I learned to reset device with "power+vol up+vol down" keys pressed together. finally the device restarted, but the device used to hang occassionally.
Googling let me know that i need to factory reset device upon firmware update for normal functioning, which i didn't do after update. so, I backed up my device, uninstalled many apps to make the device run a bit smooth and did a factory reset.. Resetting didn't improve the situation much, but now, the device display failed to light up on a regular basis on unlocking most of the time..
Now the situation is that, the device turns on, finger print scanner works, all apps n everything working, but display remains black, and touch screen is not responding.. using sidesync, everything on Tab can be accessed via laptop.
Tricks tried:
1) Factory reset
2) power+ vol up+vol down
3) power+ vol up+home key
4) power+ vol down + home key
5) Power off using sidesync and then restart
Results: All failure. Everything works but the display never lights up normally..
Plzz help....:crying::crying:
Bump. I'm starting to have similar problems with my SM-T800 running 5.0.2. I open the cover and the device fails to turn on. I press the power button and the screen stays black but the notification bar turns on. I can shake the crap out of the device and the screen stays black but I can see the notification bar flicker. Driving me batty.
If i had any problems like you guys, I would just return it to the place i bought it, for a refund or replacement or even a repair, post it to the service centre if it`s too far to travel too.
You problems sound like battery and or loose connector inside your tablet, it happens frequently on Samsung tablet for the connectors to come loose, if the tablet is dropped or twisted, no outside damage might be seen.

Rooted & Xposed: Was fine for days, then screen corrupted. Now, screen won't turn on.
I have an H812 in Canada, and recently rooted my phone with a rooted image. I'm comfortable with using CMD / ADB on Windows, and have been rooting many devices for years. Everything was fine. Used it for days.
Even though my bootloader is locked, I read that I could install Xposed via Flash Fire (in this thread). I did it, and things got a little wonky.
My phone would be fine for hours, and then the screen would get corrupt. I'd see coloured static, and visually everything would break. If I pulled out the battery and put it back in, it would boot up fine.
Over the past few days it started happening more often, until yesterday the phone was basically permanently unviewable.
Now, when I turn the phone on, the screen lights up but stays back. I can't see the boot animation. Nothing. Just a black screen.
The phone boots up fine. I can hear the booting chime. It brings me to my lock screen, and I can feel it vibrate as I enter my password. It receives notifications. It responds to ADB. But for all of this, the screen is black. It's on. Lit. But black.
Any help? Any ideas? It's hard for me to troubleshoot, as I can't ever see the screen.
Warranty it. Common problem with this phone.
In short, the phone is stuck in a bootloop unlike any I've read about before. All on its own, it constantly makes the bootup vibration pattern but it does not boot up. The screen does not light up, it is completely black (backlight is off as well). It is sitting on my desk doing the vibrate patter (bzzz-bz). Then 40 seconds later, again, (bzzz-bz).
If I could see the screen, I imagine it is going past the 1st Asus Logo screen, then trying to load the OS (2nd Asus Logo), but crashing and restarting.
This happened after I flashed fastboot (droidboot), recovery, and boot. All flashed successfully, so I went into Recovery and started to "wipe cache". It was taking too long so I thought it froze and forced a restart. After that, I never saw the screen light up again.
Any ideas as to what is going on? The phone has no damage (at least physically ).
Yes, wiping cache takes a long time you have to wait it out, forcing reboot before it finishes will result in bootlooped, that is covered in many many threads, you will need to reflash entire Rom from bootloader.
Problem is, I cannot get into bootloader. Its still doing the vibrate cycle I described, it's been 8 hours already.
Try holding the power button and volume up toll you get 2 vibrates then release power, if that does not help it sounds like your power button is stuck in depressed mode
Stuck in depressed mode? But I am able to press it, and I hear it click, and click back up. The "spring" seems to be working fine.
Hi
I got the xt-1710-09 and recently installed the android 9 upgrade which never was officially released for this version.
everything works fine except every few weeks something crashes which results in the screen always staying off. I first considered it a hardware fault since the contacts to the screen aren't that good any more which results in gfx glitches when applying slight pressure to the screen.
Now I realized when booting into TWRP via ADB the screen goes on again and the phone works for a few weeks.
does anybody have an idea what could be the cause?
I suspect the code of the fingerprint sensor. since this code already crashed earlier which resulted in the fingerprint gestures not working any more until reboot.
when the screen is dead everything works fine except well the screen and touch control. which mean the phone is almost unusable except via "ok google" speech control.
using the fingerprint the phone vibrates approval. (not the wrong fingerprint vibration)
but regardless of pressing power button or fingerprint sensor, the screen just stays black.
i believe I rebooted the phone several times via letting run the battery down or pressing the power button for a long time. this did not help. only booting into TWRP always (temporarly) solves the issue.
the phone is unlocked, rooted and twrp installed.
thanx
