Black Screen - Samsung Galaxy S9+ Questions & Answers

I have run into these issues several times. They seem to be related, but I can't say for sure.
Every now and then while I'm actively using the phone, 1/2 the screen will go away and the phone will be unresponsive. If I shut off the screen, then turn it back on, it usually clears up. Sometimes the screen won't come back on. It stays off no matter what buttons I press. So I put it on the charger, that triggers the screen turning on and everything is back to normal (the battery is always over 50% or more at this point). Yesterday this got to a point of happening several times in 1/2 hour, so I ended up rebooting to see if it would clear it up. This issue did not come back since then.
On a similar note, I was playing a game this morning in a dark room with the brightness turned all the way down. I was being very active in interacting with the screen. Every now and then the screen would go black, except for the notification bar. I could still see that (time and statuses of things running). The screen would not respond to any touches, so I would shut the screen off and turn it back on and all would be good. This happened 2-3 times over a 45 min period. I play this game quite often, but not usually in the dark and often not as actively as I was doing. My resolution is set in the middle (FHQ+ I think it's called).
Has anyone else run into anything like this?
This S9+ snapdragon through Verizon just seems to be plagued with so many minor issues. I've never had a new phone with this many problems.

As a followup, I think I have found the problem. It seems to be with a product called Game Tuner. It can black out the screen while leaving the app running in the background. I think it is buggy. Doesn't seem to be a way to shut it off though.

I was able to uninstall, then install an older version of Game Tuner and the problem that was easiest to reproduce was fixed. Hopefully this will prevent the weird 1/2 screen thing as well.

Random non-responsiveness moments?

this is random but, the touchscreen stops responding occasionally
specifically when i'm playing Mario Kart and holding the A button in for extended periods of time (n64oid)
it's not even when the system is hot it's really peculiar
actually now that i think about it this has happened a few times when i was on my homescreen as well where the touchscreen decided to stop responding yet if i pushed the buttons it still operated
anyone else seen this?
i was hoping it was ram related because i just used bloat freezer and cleaned up the ram nicely
The original X2 i had did this extremely often right out of the box (activation was a PITA)... as in it would work for 5-10 seconds (30 if i was lucky) and the touchscreen would "freeze" while all buttons and everything else were working as normal. Power button to make screen go off/on fixed it, but it would just happen 10 seconds later. Idk how bad yours is but if it is common enough see about a replacement (or hope OTA comes soon and fixes it for ya)
I'm Not Sure What It's Related To, Because I Can't Replicate It To A Certain Time Or Point Sometimes When Opening An App It Doesn't Recognize I Tapped The Icon Or When Texting Sometimes It Doesn't Know I Was Touching The Screen. Could Be Just Another Bug In The Software Which We Hope In The Future Will Be Resolved.
Its got the same feature as the atrix if one screen is pressed for more than 20secs in the same spot the screen turns off. Motorola claims to do this to protect against water damage

[Q] How to find app that is turning on screen randomly

For the past few weeks, my screen has been turning on Randomly, and then staying on until I shut it off. This happens sometimes when I'm unplugged, but more often when I'm plugged in. When the screen is on, I also find that the screen will dim after a few seconds (my timeout period) and then brighten back up again.
The up time is 13 hours on it right now, and the awake time is around 8 and a half hours, so I'm unsure if this could be considered a wakelock issue, although it has a lot of similarity's.
I know it must be one of my apps's doing it, but I'm not sure where to start to find out which one is doing it. I'm using Synergy Rom R318. I would consider just uninstalling each app until I found the culprit, but the screen on issue happens randomly, and it could go 15 or 20 without actually turning on.

Are you using an Evo 4G or an Evo 3D? I know this is the Evo 3D section, but I ask because I noticed that on my 4G right after I got even before installing any apps. It would only happen when it was charging but I ignored it assuming it did that when the battery went to 50%/75%/100%. After getting my Evo 3D, I saw that I no longer had this issue. If it is because of the battery charge levels, I'm sure you can flash a mod to disable it.
Shouldn’t you be able to use an app like Watchdog Task Manager by Zomut to track the app down?

I'm gonna run logcat and see what pops up.
This happened to me on my Evo 3D as well. It was happening using SteelROM ROM. It was odd because it was on the desk, disconnected, and it'd light up and, if I didn't touch it, dim down and then brighten up again, and would not shut off until I clicked the power button to "lock" it.
After I flashed ShooterRewind RLS3, I haven't had this issue again. I don't know if it is ROM related, or something else that was replaced with ShooterRewind.
Just something to consider, though I'm no expert. Also, each ROM comes with its own set of apps, and with some other apps removed. So it could have been one of the apps that was on SteelROM but not on ShooterRewind. I am using RCMIX 3.0 beta kernel, if that makes any difference.

[Q] How do I force the screen to stay on while charging on USB?

Running the newest UnNamed and I'm trying to find a way to keep the screen on while charging from USB. The point is to keep the screen on while driving. At night I charge with AC power so that's not an issue.
I found posts saying there was a burn in problem with SMOLED screens being on with a static image for more than a couple minutes at a time. I haven't seen it personally but if anyone has first hand experience with this phone or the international model, please speak up before I damage my phone.
Otherwise, once again, it looks like I need Tasker for the job. Have it detect bluetooth connection for the car and upon usb power trigger car mode and keep the screen on at ~50% brightness. something like that.
With unnamed go to Settings>Applications>Development and click Stay Awake.
Try this first,
Menu->settings->Applications ->Development -> Stay awak
If not working , try this
Menu->settings->Display->Screen Timeout ->Never
Now I've never seen permanent burn in on my SGSII or Nexus One (even while on constantly during a 10h drive to Vegas). I was using a stop watch app on my Nexus One, and while only on for 5 minutes or so, I did see it burn in, but it went away after a few minutes of being off (boy was I scared when I first saw it though).
Now, I have personally seen permanent burn-in on a Vibrant (not mine).
Funny thing is the screen timeout is set to like 5 seconds on it, so it's barely on. Yet I can clearly see the clock is burned into the screen.
Have you tried running a car app to hold a screen lock? I know Google Maps can do that. Plus it doesn't require going into settings (at least more than once).
EDIT: As a simple observation, the burn-in seems worse when it's white on a black background.

A few things I have noticed

So I have had time to play with this for a solid day and a half now and have a few problems:
1: I think I have the bright spot issue. I didn't notice until this morning but now that I have, its very bothersome. Its not a dead pixel, just a small spot that is brighter then the rest.
2: I can't use my power button to turn off the screen or power off the device. It worked for about 3 hours and then it just stops working. Don't know what is causing this problem. I can only fix it by rebooting via adb.
3: I guess I'm getting the reboots too. I was typing all of this and my screen randomly turned white and grey and then rebooted itself. I saw there might be a possible fix but haven't had a chance to look at it. I will tomorrow when I'm at work.
4: I can't make custom alarms? I have it under /sdcard/media/audio/ but I can't see it in the alarm selector. Come to think of it... I don't even have a sdcard in...
Think I should return and get a different one?

S6 Edge screen won't turn on (but otherwise works fine)

Hi everyone,
I'm sure this question has been asked by many users, but for some reason none of the ones I read seem to match the problems with my S6 Edge.
The other day I was playing music Youtube on my 3 year old S6 edge (for like 30min) and I forgot that autoplay was off, so the screen turned off, within 10 seconds of it doing so, I pressed the home button to 'wake it up again', but the screen won't turn on. the phone reboots once by itself but the screen remains off, and I know the phone's on because of the blinking LED light of messages, or the red when it is charging. The backlight lights up too, and it seems the screen's touch system works, as I am able to turn it off. I wait for a couple of minutes before hard resetting it (Volume down+Power key) and the screen lights up again and it's all good.
However, I have noticed this happening way too many times lately and noticed a bit of a trend. It usually happens when I use any app (except the music app) for 30 minutes or more, and if I manage to keep the screen awake, it works perfectly fine. The problem begins when the screen sleeps due to inactivity, or is voluntarily turned off. It also heats up quite a bit.
I am on the latest firmware, and have already formatted the phone once and tried, yet the problem persists. With that I suppose we can rule out that the problem is due to any third party app, or due to not updating the firmware. I also replaced the motherboard last year at a reputable phone repair shop, so I think it's a safe bet to say that's not the issue, but I am not 100% sure (the problems began 6 months after I 'unrooted' the phone, after replacing the motherboard).
As I kept going with it, it kept getting worse until eventually, now the phone is in a constant state of 'screen off but phone on', where it charges, plays music, can receive calls and messages, but cannot turn on the screen. I kept trying at 15 minute intervals to no avail, even though the phone is at room temperature.
Before I go blow a couple more 100 bucks on fixing this, I would like to hear all of your opinions on what the problem might be (and hopefully the solution).
Thanks in advance.
i have the same problem but i have the galaxy s7 edge. often i can unlock my phone but my screen will stay black. no aod or backlight but the vibration from unlocking with fingerprint is there and the sounds of opening an app are also there...
