[Q] Screen will randomly not light up - T-Mobile myTouch 4G Slide

So my phone has been fine until yesterday. Everything seems to be working except the screen won't show anything. I can feel the vibration from unlocking as if it was showing and I can still hear sounds and the buttons at the bottom and the keyboard all light up but nothing shows on the screen. If I take the battery out and put it back in most of the time it fixes the issue. Sometimes it doesn't even show the splash screen though. Its kind of hit or miss.
I replaced the ROM I had on and put the original battery back in (I have an extended battery) to make sure it was neither of those issues. My guess is something is going out on it. Anyone else have this happen/have a fix?

Also forgot to mention this doesn't happen if I boot into recovery.

Are you using a custom ROM? If it doesn't happen on recovery then sounds like a kernel issue to me... Since the only difference between recovery and normal mode is the kernel they're using is different.

I am, yeah. I ended up going into recovery and formatting everything, it was still acting up for a bit after that but then started working fine. My guess is I had some sort of corruption. Thanks

Same thing was happening to me when I went ham on my kernel tweaking the hell out of it :silly:

Well I mostly fixed it. Still happens randomly when sliding out. If I slowly slide in or out again that fixes it though. Still, kinda of a weird problem.

[Q] screen issue....maybe?

I got my charge as a replacement for my fascinate like many others. befor i do anything i wanted to give the phone a few days on stock to make sure everything works fine. So far the only thing i noticed was sometimes it lags when i hit the power button to turn the screen on. Sometimes it flashes a static filled screen for a split sec before home screen loads. also some times it takes a sec for my screen to come back on after i lower the phone from my face so i can hang up. Is this just a little minor known issue others are having or is there something wrong with my phone possibly? Phone is all stock, fully bloated and the only apps ive installed are xbox live stats and google googles (coolest app ever). I doesnt do it all the time but it happens frequently enough to notice it. I can normally recreate it if i hit power button to turn screen off and let it sit a few mins then hit the button again to turn it back on.
When running completely stock, I experienced the same 2-3 second delay. Now that I am on EE4 with a custom kernel, the delay is closer to 1 second.

did you ever see black/white lines or static? I only ask because if its a common thing that most have exp then its really no big deal. ill root and flash to help fix the lag. But if its not then i would like to get it fix asap. Other then that i havent seen any other issues yet.
I see the lines and"static" on mine when the screen comes on. Not every time though.

I have seen it on occasion. It's much less noticable on a custom kernel and ROM.

Thanks for posting everybody. It seams like its a common issue then. I just wanted to make sure it wasn't just mine or that i needed to return it due to some kinda of defect. Nice to know a custom kernel will fix it for the most part. Thanks again guys. This phone is so much nicer then the fascinate
I set a lock pattern on my phone, and I haven't seen the screen flicker once since. I'll switch back to the puzzle lock and see if it comes back....standby.
*update* switched back and still no flicker. Maybe that's the ticket.

I have it on two replacement phones I got through amazon . White lines for a split second . I got it replaced through verizon because both of the others had a dead glowing red pixel after about a week. The one I got from verizon works great I would get it replaced asap before u get the glowing red dot of doom

[Q] screen blackouts (NOT ROOTED)

this morning (and maybe 2 other times before) my screen blacked out and refused to turn back on. i am not rooted. any ideas why this would happen? i ended up having to pull the battery twice and then it's been working fine since.
thanks
then that was probably it...if it continues, do a factory reset

What ROM are you using? I've had that happen to me twice now. The buttons light up, I can hear screen noises, but a black screen. I pull the battery and reboot, everything is fine. I'm using DS_MOD.1.55.531.3, rooted and S-OFF.

yep. i figured i'd wait as long as i can before i decide to root (really don't have any reason to... i've always rooted my devices, my G1 and G2... just don't really have a need to yet with this phone)
I'm running Rubix v5.3 ICS Splashed, and the same exact thing happened to me tonight, weird...
Pulled the phone out of my pocket and screen was black. You could hear lock sounds and keys light up but the screen stayed black.
Pulled the battery and all is well again. This can't be a coincidence, can it?
This has happened to me periodically both on stock and on bulletproof, I never really gave it much thought though, because it was easily fixed by a reboot.

i'll probably just end up forgetting about it soon enough, but it's just annoying that our phone should have an issue like that. if i had money to switch phones whenever i want i'd already have left it because of this issue, you know what i mean?

It's been progressively getting worse, now I get just a black screen nothing coming up after multiple charges and battery pulls... praying it's not the screen and just a battery problem!
If it's fixed by a battery pull at first then it's most likely just a battery issue.

No luck after battery pull, you think it's screen then or flex cable? The screen worked like 8 hours ago with minor black-outs one or twice a day to more frequently and random reboots like 6-8 just today!
Flex cable could cause flickering. You're really quite SOL with it then.

Camera Flash Shutting Off Phone!?

I rarely start a thread and i typically search first and i did that already but couldn't find an answer or someone else with the issue...
So my problem is simple but annoying... When i snap a picture with the stock camera app and flash turned on, randomly my phone shuts off and will NOT turn on again until i do a battery pull... I say randomly because it doesn't always happen... But it happens quite often...
I haven't tried with a 3rd party camera app because I prefer to use stock apps mostly... So I'm not sure if its app related or hardware related... I'm leaning towards hardware because I've had this issue since running 4.1.2 ROMs and I've tried multiple stock/modified camera apps to no avail... Currently on 4.2.1 ROM with of course the 4.2 camera...
Torch toggle works fine, as well as turning on the flash while recording video... This ONLY happens when the flash comes on for taking a photo... And again it only happens randomly...
Anyone else experience this or know how to fix it?

The first thing I would do is flash factory Google. This will rule out it being a ROM issue. If the problem is so there then yes it is a hardware issue.

Strangely, it was doing it before i got a new battery a couple months ago... I sorta felt my battery was bad so i went to get a new one from the sprint store... The guy said because "It was rooted and the phone had so much awesomeness.." it was draining the battery faster... I told him a quick reason why i thought it had to be the battery and he just gave me a battery from the drawer without doing any paperwork or anything... My battery wasn't feeling any better after the change and i still had issues with flash...
I think I'll just take some photosphere pics and well lit shots... Who needs flash anyways? Lol
Sent from my Nexus S 4G using Tapatalk 2
I have the EXACT same issue however long pressing the power button turns on the phone instead of pulling the battery. It also started happening to me only on jelly bean. My GF has the same problem.
I can also tell you it happens with camera zoom FX as well but this cannot be a hardware issue since it only happened in jelly bean. It cant be that "suddenly" our phones developed a problem.
Is nobody using a nexus S to take photos or what? Or is it just a few unfortunate users affected by this?
Thanks for that post... Now I know I'm not alone here lol... I too noticed it with JB... Its %~°^¶©£ annoying... I wish a dev would look into it... I think it may have something to do with the flash having that instant jolt of high voltage... Idk because I'm no expert... I found a 50/50 chance of making it work correctly... If you hold the shutter button to let it focus, then let it snap, there's a chance it won't shut off... Just something to try and see if it helps!!

just did a complete factory restore back to 4.1.1 unrooted and everything... forgot to test the camera... i rooted again and installed custom recovery... tested camera out several times... no issue at all... tested some more... no issues... decided it WORKS!! so i flashed cm10.1 and updated everything again... tested camera and OFF!!! FU%$&*&@&#&^$%$^@&$^&$^^%$#^%@*@*@&&#^*&@^#*&^@#*^ i'm at a loss for what to do here... i'm glad one other person reported this... but there HAS to be more people out there with this issue...
test it... make sure flash is ON and snap a few pics... maybe a close pic out of focus, etc... idk what else to do... it worked fine unrooted...
I've had this issue happen randomly to me too...but usually only when my battery is low. And it is VERY annoying when it happens.

doesn't matter my battery level... it happens on my charger too lol...
I didnt have this problem last night on a wedding thankfully as that would have been embarrassing, lots of pics were taken with flash. Its the sheer randomness of this that it makes it so hard to diagnose. :S
I've been having exactly the same problem. I cannot relate it to Battery Levels, as the battery drains sooo fast since I got the ICS upgrade.
I am now on the Factory ROM 4.1.2 and it is all problems. I am thinking of going back to Ginger Bread... them were the days!!!
J.
if you read above, it worked fine for me when i flashed 4.1.1 factory image... something to do with 4.2 i guess... idk... i'm not stressing it so much... i've learned not to use my camera when its dark or low light lol...
have the same problem

Its a Battery Problem
I'm suffering from this same issue and after downloading several camera app to no avail, the issue is finally resolved. From my experience, I can safely conclude that my was a hardware battery issue. At first I didn't believe it was a battery problem. I decided to go to different stores and tried several batteries but all shut down the phone when the flash on/flash auto + taking a snap is executed. Then, I pulled out the battery from my friend's brand new S3 and inserted it in my phone's battery compartment, fire on the phone and voila the camera flash worked like a charm without shutting down the phone. I used the same old battery on the new S3 low and behold, the new S3 inherited the flash+camera=shutdown issue instantly.
Same Issue on SGS2 Hercules
Having this issue after flashing a ROM on my GS2 Hercules, good thing I only experience it when my battery level is below 25%. But it would really be a pain if I would want to take a picture with a flash while my battery is low.
Have anybody tried other solution or troubleshooting aside from trying a different/new battery.
similar problem here...
the same thing happens to me, but with the difference that i run stock 4.1.2 rooted, and when the phone die after the led flashes, i just press pwr button and the phone turn on like never was happened.
i think it's a problem of corruption of something in the system, if i do a factory reset, for some limited shot the camera+led works, after that the phone die instantly.
similar problem with front camera, if i switch from back to front the camera service crashes and i can't do anything for make it working (manually stop the gallery process, reboot, cleaning data of gallery process), just wait some days and the process came back working (just for the rear camera).
sometimes i notice that while the stock camera app doesn't work, the Whats app camera keep working also with flash!

same issue with the nexus 5.. taking pictures works and then suddenly shuts down the phone, the power button can't wake the phone and the only way to get it to turn on is to plug it into an outlet.. very annoying.
that said I looked around the forums and it seems like a hardware battery issue, when the voltage supplied is too low or high or something
flash has caused my phone to shut off.
got GS3 SCH-i535 I've noticed the flash causing the screen to black out completely and shut off phone. I usually have to pull battery. its done it on 4.2 and 4.3 probably even 4.1 i dont remember I'm currently running 4.4.2. it just did it again which has prompted me to look online. as glad as i am to know im not the only one. is there any ****ing solution???

[Q] Need help with blank screen after replacement

Hi all. I'm having an issue with a 727R. I replaced a broken screen and now can't get the screen to stay on. Its a non rooted, factory 2.3.5 phone. When I turn it on, the sghi-727r screen pops up for several seconds and then dissappears, phone vibrates once, notification sounds appear shortly and all touch functions appear to work (by sound and haptic feedback). For all intents and purposes, this phone is on and working perfectly...if you're blind lol. I know the replacement screen works because it works perfectly if I go into download (odin) mode. I've been searching threads and haven't been able to come up with a solution, as most of the other blank screens are from bad flashes. Keep in mind that I am also testing this with the casing removed as it is a repair for a friend (if that makes any difference). Any help or ideas would be greatly appreciated and thanks in advance.
Is the brightness maybe turned ALL the way down? When it finishes booting shine a flashlite on the screen and tell me if u can see text, icons etc...
I'll do that as soon as I get home this afternoon. I could only hope that's all it is, but i'm a little skeptical that I could be so lucky. forgot to mention that I have also odin flashed the stock rom back on just in case of software corruption. I would also think that I would get full boot logo's during the boot sequence, but hey!....its definately worth a shot! I've seen stranger things . Thanks for the quick response.

No worries, keep us informed. I didn't even bother to ask because I just assumed someone at your level who can change a screen would intuitively know to Odin stock... I was right :good:

So you had display for start of boot and d/l mode? If so, then I'll go no farther until I get another replacement screen.:crying:. Come to think of it, when plugged in and off, the charge symbol shows up for a second and its discoloured (almost like its made of vertical lines that are pinks and grays). You may have just saved me a lot of time. I was leaning toward trying to adb error logs in hopes of finding something. Other than that it was going to be a reflow on the gpu since the phone did do a leap of faith from 6 ft up....and lost lol.

ok ill try that. but here's the thing. whatever app i use to turn off the backlight of the soft keys. it only dims it to the lowest level and doesnt completely turn it off.
when you look at your phone in a different angle, you can still see a very small light emitting in the soft keys part even when you shut off the phone. i tried reinserting the battery hut it doesnt fix the problem.

Make a backup, do a full wipe in recovery, and reinstall the ROM you want fresh. If the propblem goes away then something is just screwy in your current ROm install and you may just have to set up a fresh install of it.

i hope your right that its just a rom problem because sometimes out of nowhere, all of a sudden when i shut off the phone, the backlights were completely gone(which is what i want to happen).
I'll post the results later. thanks.
by the way, when i used cpu spy it doesnt turn into deep sleep when the screen is off even if there is no apps running.
i left the phone for 6 hours screen off and charging. and only 8 minutes it turn into deep sleep state. the other remaining comes from my lowest speed which is 384. so im joping its just a rom problem.

Wait a minute...when you said the backlight stays on even when you shut off the phone I thought you meant like when you turn the screen off. Do you mean when you physically power off the device?
That's really screwy. If so, something is really REALLY messed up.
Try the following 3 things in this order from easiest to hardest.
1) Remove the SD card. Reboot the phone. See if the problem persists. If it goes away without the SD card, copy your files to a computer, format the SD card, and copy your files back. I give this a 10% chance of working but its quick to test it so why not try?
2) Do a full wipe. Flash a bone stock Sense ROM. Seen if the problem goes away. If it does, wipe again and install whatever you want.
3) Run a full ruu and return to completely stock. If the problem is still there your hardware is broken. If the problem goes away you will have to restart the rooting process. You will have to redo s off, redo superuser, etc. Then flat whatever ROM you want.
Try doing an full ruu back to bone stock. Reroot, and start over with a new ROM. You will have to go through the whole s off process again. But it might fix this. And form the sound of it you have somehow borked things that shouldn't have ever been touched.

3) Run a full ruu and return to completely stock. If the problem is still there your hardware is broken. If the problem goes away you will have to restart the rooting process. You will have to redo s off, redo superuser, etc. Then flat whatever ROM you want.
Try doing an full ruu back to bone stock. Reroot, and start over with a new ROM. You will have to go through the whole s off process again. But it might fix this. And form the sound of it you have somehow borked things that shouldn't have ever been touched.

Well, when the phone is off, the backlight is already gone. So its ok now. The CPU spy also states that when I turn my screen off, it turns into deep sleep. That one is fixed too. But when I charge the phone and let my screen off, it doesn't go into deep sleep but it consumes the least frequency of the processor which is 192mhz I don't know if that is normal.
I think I have a hardware problem since I sent my phone to replace its microphone flex which includes the lights coming from the buttons. I'll try to send it back to the center since it still has warranty.
Thanks. I'll update you.

Any update on this issue? My wife's phone has many screen problems, but one of the primary symptoms is that the backlight is almost always on in the lower left corner, even after removing the battery and reinserting it, before booting. When I charge it, the backlight gets brighter and I see dark pixelation across the screen. At times the screen has crapped out completely, and it usually appears dark, has some light flickering, blotching, and vertical lines. I'm wondering whether this is an LCD/backlight issue at all or another hardware issue. Don't want to buy an LCD if that won't fix anything. Some LCD/digitizer assemblies have a mic cable, though, so I'm curious about what you found out about that. Thanks
