S6 screen flickering - Galaxy S6 Q&A, Help & Troubleshooting

HELP!!
My S6 screen has suddenly stopped working as of tonight. When I boot it up the logo screen doesn't appear and instead it's all black until it boots up. Then it flickers from about 30 seconds to about 3 minutes and I can't do anything until it comes on. Also, I can boot into download mode but I'm also met with a black screen. Recovery is the only mode where the issue stops.
Is this a HW issue that I'll have to take in? Or is this just a software issue I could fix by reflashing?

If it works fine in recovery, it's most likely a software issue.
Reset/Reflash. That should fix the issue.
Try wiping cache first though.

I've tried reflashing and resetting, but haven't wiped my cache yet. I found out that it only happens when my brightness goes down.

Well now it sounds like a hardware problem. Have it checked out at the service centre.

Help - Stuck in Reboot Hell

I've been using my N5 just fine for the past week or so and all of a sudden it seems to be stuck in a bootloop. I try to get into recovery but it just keeps rebooting out of that. I rooted it a few days ago. I don't know why this is happening, I have no custom roms on it. Any ideas?

Seems to be a messed up power button. sometimes it comes on for a minute, but the power-off menu keeps flashing.

Can you get into fastboot mode and then in recovery and data factory reset and wipe the caches? If that doesn`t help reflash the factory image in fastboot. Good luck bro.

That worked. Just a factory reset did it. Guess it wasn't my power button. Whew! I love this phone and nearly had a heart attack.

Powering off upon boot

I woke up to find my phone off, I knew the battery was charged so I turned it on, when the phone booted and got to the lock screen the powering off box popped up and it shut down. I tried multiple times to boot but every time the powering off box would pop up and the phone would shut off. So I booted into recovery and wiped the phone, that didn't fix it, the phone is still shutting down upon boot, does anyone have any suggestions?
Update: I have flashed the stock rom and wiped all the caches and its still shutting down once it gets to the lock screen. Its almost like the power button is stuck, but I'm able to navigate in recovery fine so I don't believe that's possible.
I followed the steps on how to unroot and reset the phone to completely stock and the problem still persists, anyone have any idea?

If you have flashed the factory images and so on and all of this still persist than it's RMA time.

[Q] White Screen Stucking

I've flashed .14 ftf using flash tool, flashed thunderzap 3.1 ultra & then rooted my device. Whenever i'm using the mobile, a white screen is appearing suddenly and stucks for 5-6 secs and gets back to normal. It is happening again and again for every 5-10 mins. When that white screen appears, everything gets stuck, like the soft touch keys etc. What to do ? What the hell is happening to my XL ? Is there any way to clear my problem ? :crying:

Try flashing new kernel through CWM after which wipe dalvik and cache
Then boot into recovery and flash any ROM (For e.g. MagicXL)
Then setup everything
Do not restore backup, it may be the cause of the problem..

Does your device responds when your screen goes white?
I mean if you are playing songs and screen suddenly goes white, does the song pauses/stops or it continues to play?

If the screen goes white while playing a song, the song doesn't pause, it just plays as it is but the screen doesnt respond at that time

Factory reset as in the option in Settings or flashing the .img files in fastboot while in bootloader?
If you bought from the Play Store, RMA is when you claim your warranty and Google sends you a replacement.
If you didn't buy from the Play Store, then you have to send it to LG for repair.

Won't be a stock kernel issue. It's most likely an issue with your device.

It has to do with the phone because the WiFI antenna and other hardware is in the phone?

[Q] Restart loop(not bootloop) - really weird

Hey lads,
I got a really weird problem and I've tried nearly everything I can think of. I had EMUI 2.3(b121sp06) and I tried the online OTA update to b307 if I remember right(was automatically suggesting the update) and at the update screen it loaded to about 99% and then stopped. Said not to press power while on this screen but obviously it wasn't going to finish. So I reset the phone and it started the "recovery loop", so basically keep trying to apply the update. I had to flash CWM to break out and flashed the whole system by hand(recovery,system,boot,cache,cust and userdata img files) and it starts up but it keeps resetting and seemingly it's random. Android boots up, I don't touch the phone--> boom reset. Weird thing is it even does it in recovery.
If I really want to explain the problem it's like as if my finger got stuck on the power button(that naturally made me think that the button might be f*cked), but booting into fastboot and not having resets cleared my suspicion. What I also noticed is that every time it boots up it doesn't recognize the sim card and I have no signal or whatsoever.
Tried multi tool unbricking method -> doesn't work
Tried factory reset from stock recovery(had to be fast so it doesn't reset before) ->doesn't work
Tried wiping dalvik cache and factory reset from CWM ->doesn't work
Tried killing battery by letting it keep resetting -> battery drained, reset loop stopped ->put the phone on charger->reset loop started again
I have no f*cking clue how can I get out of this, will keep trying though. Any help is appreciated, thank you!
Hi
Did you try to remove the Sd Card ? Honor 6 reboot is often due to faulty SD Card.
Which model do you have ? L04 ?
B307 upgrade sure ?
Seb
Yes, that was my first idea, still does it though. I have the L02 and I'm not positive it was b307, but it started with 3, could be b303 if there is one.
I don't know for L02 but for L04 there is a Full ROM that you can flash with the three buttons method. (Vol+,Vol-, power and put the ROM in /dload folder on the SD card).
Maybe there is such thing for L02 ?
There is, but as I said the phone restarts even in recovery. It's like the phone restarts every 30 secs except for fastboot.
if it's not SD card or internal flash problem so, it seems to be hardware related to me (
Would make sense but it occurred only after I tried OTA. Would be really surprised if that killed that hardware :-/

Unfortunately not, I'm out of ideas, trying to negotiate with the seller to sort something out, I think the phone is beyond saving
Same thing happened with me. Don't have any solution. Have you fixed it?

Its might be a battery problem Or power flex cable. Try to turn on the phone during charge
guys im facing the same problem now... waiting for any solutions
I have tried stop & uninstall some app
I've tried as quickly as I can when the phone (nokia x) is on, then I stop> uninstall I consider potentially cause this problem (facebook, whatsapp, uc browser) and then it managed to prevent the continuous restarts. but problems arise even though the application had me uninstall and then I restart the phone. and it is back again, I uninstalled the app that has remained with the error settings and restart repeatedly. who knows what else : '(

Did you follow the guide here?
Sent from my Honor 8 using XDA Labs
In the past my battery lost it's endurance pretty much. Furthermore I've read that a defective battery causes lots of weird behaviours on our Honor 6, which was the same to mine.
In my case a replacement of the battery worked well, to get my Honor 6 back to life:

It's not that difficult and lasts approx. 30-45 mins. Spare Batteries are available for 6 - 10 bucks on ebay or directly from the chinese internet stores.

It's really important that we use original chargers for the health of our device.
