Possible SOD issue...

Hey guys so my Tilt 2 has been having an issue when I put it to sleep. It goes to sleep fine, but when I wake it up the screen remains black. The actual device turns on, but the screen stays black. I can still make calls, receive calls, play music, etc. but I have to soft reset the device if I want to be able to see what I am doing.
From what I can tell my problem is different from the normal Sleep of Death issue where the device simply won't wake up.
I've searched through the forums looking for solutions and have tried pretty much everything from doing a hard reset, using different roms, formatting the internal memory, etc. Even after doing all of this, my device still suffers from this issue.
Any insight into my problem would be greatly appreciated!

I assume you've tried a simple reset using the reset button or pulling the battery out and putting it back in?

Yeah every time I the screen goes black I soft reset it in order to get the screen to turn back on. The problem is that the issue persists through soft resets. I currently can't suspend my device because I can't get the screen to turn back on...

hold down the volume down button and then press the reset button (the physical reset button) this should bring you into your bootscreen the multicoloured screen.. if you can get there then you can flash a new rom on your phone... and thats a whole other ball game. It gets a lot of hype as being hard but its really super easy to do if you just follow the directions.

Tilt 2 dark screen solved
With the tilt 2, if the screen does not wakeup, but you can answer the phone, hear music, etc..., it is a malfunctioning light sensor, maybe hardware, or software related (drivers), but it is fixable. Just eliminate all calls for use of the light sensor.
I had this problem and took quite a while to figure it out, as there are several apps that poll the light sensor that cause problems.
First, go to start/settings/system/power/backlight and uncheck the auto adjust backlight option
Second, go to start/settings/personal/buttons/backlight and uncheck the enable keyboard auto backlight sensor.
Last, open advanced config (need to download and install from touchxperience.com, if you do not have it), tab to light sensor and set light sensor polling to disabled.
Now, my phone works normal and will wake up properly from standby like it should. this all seems hardware dependant, as I have in my family 3 of these things and I dropped and broke mine, so bought a new one (4th in the series) and it had the SOD issues, but could restart with softrest. Took me the better part of the day to find a reliable fix, but now all is well again.
Hope this helps other Tilt 2 and similar issues.

[Q] Variety of strange screen issues occuring

Apologies if this has been addressed before, but I searched and couldn't find something exactly like this...
Randomly one of 3 screen issues seems to be occuring on a daily basis:
1) Auto-Rotate stops working. Cannot get screen to rotate without reset (Yes, I've made sure auto-rotate is on in settings)
2) Screen will not Auto-Off. Even if I change settings to 15 secs, screen will not turn itself off. I have to manually turn it off. And, if I receive a text or any kind of notification it will light up again and stay on indefinitely.
3) Screen will not turn back on when trying to wake up device. Hitting the home button and power button both have no effect. Although the LED is usually blinking, and it seems the phone is still on.
For all 3 of the above issues, manually pulling out the battery and reseting the phone that way seems to always work. But, this is an annoying process to have to go through on a daily basis.
Also, I've noticed that these 3 symptoms don't occur simultaneously. For example, yesterday it wouldn't auto-off, but rotation would still work.
Not running any custom ROMs either

Screen too dim, backlight(Maybe) not working.

Hi all. I have a rather weird issue. After droping(oops) my phone, I ordered a new lcd. I shelved the phone as it was unusable until the screen arrived. When the screen arrived, I saw that the battery was dead. I charged it and changed the lcd. That's for the backstory. Fast forward to now. When I open the phone, the screen lights up at full brightness as one would expect at the android one logo. It stays there at full brightness for about 8secs But as soon as it starts loading android the screen dims to absolute dark. In the beginning I thought the phone was closing, you can't see anything... Unless you close the lights.
But even in absolutely dark room, the screen is still very dim, barely discernible. The phone works absolutely fine otherwise, touch camera sound etc. I backtracked the process and put it's original screen on, but it does the same.
I tried disabling auto brightness it does nothing. In fact, changing brightness from the slider does absolutely nothing whatsoever.
Tried calibrating the sensors from the engineering menu(not sure it was called that, the one you enter when you put numbers on the call menu) they seem to be working, but the brightness doesn't change.
Tried removing the battery for a prolonged amount of time (around 6 hours iirc). Still same.
At this point i'm thinking:
1)Software problem. I will really need to hard reset the whole thing, which i'd rather not, and hope for the best.
2)Bad screen, which doesn't explain why the previous one has the same problem, or why the screen works during the logo.
I hope I was able to give enough info. Any help would be greatly appreciated. Thanks!

Hi, I'm having almost the same issue (display very dim, but for me it is always very dim) and this manifested not after any dropping or screen replacement, I guess I just wrongly inputed a button sequence that configured the mobile in this weird status. It is really annoying as it is almost impossible to unlock sims, basically the phone is unusable, very frustrating....

Hey there, did anyone found a solution for this issue?

Has anyone solved this problem?

Have you found what was causing this?
I’ve the same issue, replaced the lcd on a xiaomi mi a1 and the backlight is present at the logo startup but completely black after that.[br]
On a dark room I can barely see the screen and all it’s working, but adaptive light button is missing, seems like the bootloader is able to use the backlight but not android itself

I have the exact same problem, i really hope someone knows a solution to this. I tried pretty much anything within my capabilities

Black Screen

So my phone has had some tumbles during me using it but outside of some cracks the phone was mostly fine.
Sometimes the touchscreen wouldn't respond properly but locking and unlocking the phone always fixed it.
After waking up and using my phone for about 10 minutes, My phone's screen suddenly went black and it won't show anything anymore.
It's not black as in not turning on, because I can see that the backlight turns on. it just doesn't display anything else.
Can this be fixed by just replacing the screen? or is there any other fix, which i doubt

Same here...?
Did you get it repaired. What was the problem..?

Same issue

I am facing the same issue of Screen getting black. The sound keeps on coming but the display turns dark. It gets normal after a restart.

Always on display "flickering" when activated (on tap)

Hey everyone!
As the title say i'm facing a issue with my always on display.
I'll try to make it as simple as possible:
When I set the always on display to be always active it works flawlessly.
When I set the always on display to activate on tap (and last for 10 seconds according to the settings) it appears for roughly 3 seconds and then disappears for 3-4 and reappears flickering for 2-3 times sometimes showing the desktop wallpaper between each flicker.
Did anyone experience the same issue?
What I did to try and fix it was:
- tested both on battery and while charging
- factory reseted and then restored backup (which was stupid, that lead me to the second point)
- start in safe mode (to check whether it was an app causing troubles) but no such luck, problem still occurs.
- uninstalled "nice lock" apps
- changed some settings under the always on display tab
- cleared cache of the always on app
What you should know:
- I'm running android 9, not rooted and have nova launcher as default home
- After I factory reseted the phone I wanted to stop always on display from updating to test whether it was a new version issue but I forgot and didn't make it in time so I'm currently running the latest version
Does anyone have any idea as of why it's behaving like this?
edit: just wanna be a little more clear, flickering is not meant like a lightbulb it's more something like it turns off and back on after a delay (I'm sorry english is not my native language I can't really explain it any better)

i also experience the same.
this phone has many strange bugs.
when i restart my A70, tap to show always on display works for me for 2-3 times.
after 2-3 times working correctly, the bug starts.
after i tap the screen, it shows AOD for 2 seconds. then turns the screen off and then at the end of the 10th second, screen just flashes itself for the last time and turns off completely.
i think it is related to the fingerprint scanner.
because after i registered my fingerprints and turned on unlocking the screen by the FP reader, this bug ends.
after i tap the screen it shows both the clock and fingerprint icon at the bottom of the screen.
after 2 seconds fingerprint icon disappears. and the clock is continued to be shown until the end of 10th second.
but there is a minor issue, when the fingerprint icon disappears, the AOD screen brightness changes. dims or brighter slightly.
can you please try tap to show AOD, by enabling the fingerprint unlocking?
samsung ?

Hey! Thanks for the answer, I can confirm we have the exact same issue. I also have the same brightness issue you described
Anyway, I have always used fingerprint unlock though so I don't know what to answer you.. I only recently noticed the weird behavior. I did a couple things to test and I found out that enabling the "fingerprint" icon showing in the always on display seems to "fix" the issue of the flicker but not the one of the brightness change (after enabling it i've yet to see the problem occur), you should try it and let me know if you see any improvement. It's probably on samsung's end though and hopefully we get it fixed with android 10 or earlier
I'll take this chance to ask you another question; two weeks ago I received a software update and ever since that day I noticed my battery to be lasting waaaay less than it used to, did you update your phone as well? Did you notice a battery drain?

I have the issue both of you talking about.

hello, I had this same issue and what I did was turn the phone off, and booting it up while pressing "Volume Up", after entering a black screen with many options, I selected wipe cache. It has worked without a flaw since then. There's lots of bugs with this phone. I recently had a problem where the USB port will detect a device and "plugged and unplugged" it, making my phone unable to dim. Thankfully I was helpful.
