Weird glitch before lock screen fingerprint appear - Samsung Galaxy A50 Questions & Answers

Hello,
Recently my phone started to show the background picture with the nav bar for few seconds, then right after the lock screen, I never experienced this before since I bought it.
Anyone know what could cause this and what can I do to solve the issue or report to Samsung?

I have been seeing all kinds of weird stuff with the A50. Apps open after I unlock the screen, my Samsung browser home page gets pushed back to google.com ever 5 or 6 days. This is the first phone I have seen these kinds of strange things happening. I have Android 9 on other devices and never see these types of issues. I did factory resets and still these things happen

Keyboard and Home screen wallpaper keep changing

OGP was getting laggy so I restored to factory stock. I was surprised though that the phone remained rooted, which I guess is good. I then installed FreeGee and went with CWM, same as it was before the restore.
Now, a few weeks later, I'm having some issues with the keyboard and the Home screen wallpaper. About once or twice a day (on most days), for some unknown reason, my keyboard will revert to the Android keyboard (AOSP) from the LG keyboard that I have it set to. When I "correct" it to the LG keyboard, sometimes the "Extended keyboard" option is checked and other times it's not (I always leave the extended keyboard checked). I also will occasionally get a notification on the pull-down that I need to select a keyboard.
The other issue is that the Home screen wallpaper also seems to change itself back to the default blueberry paper. This only happens on the home screen, and it does not affect the lock screen wallpaper. The wallpaper issue seems to happen at different times than the keyboard issue.
I've also had the phone reboot itself once or twice since the restore...both times while in its holster. Only reason I know this is that I hear the AT&T boot music playing in the background. Upon viewing the phone, it's verified that it is in fact rebooting.
Anyone else having these issues, or know the cause?

Guess nobody else is having this issue.
The spontaneous rebooting has stopped, as has the "extended keyboard" issue.
What remains is the wallpaper and default keyboard changing issues. They both change at the same time now, about once a week.
What I was able to nail down is that this happens after every time titanium backup (free version) does its weekly thing. I have no idea what setting(s) I may have enabled to cause this. Anyone have an idea they can help out with?
I have the exact same problem with my home screen wallpaper changing. Ive had my optimus since about july and the first time it did it was like 2 weeks after i got the device. Kept doing it even tho i would change it back and not do anything with it regarding the screen. Wasnt sure what to make of it but whatever. It didnt do it again until yesterday (24th) and it wouldnt stop. Had to change my screen back like 5 times, and i just woke up a little bit ago and it was different again. The phone was just laying there. Didnt touch it so i have no clue. Ive tried going thru the settings to see if maybe i had checked something or whatever and im pretty sure i didnt. Only thing i can think of is that is just a glitch with the phone. I like the phone too much so thats not enough to get me to wanna get rid of it.

Are you running Titanium Backup?
If all else fails, you can always restore to stock and reinstall your apps and other items. Then maybe you will be able to determine what is causing the issue.

[Q] Galaxy S4 Shrinking Lock on lock screen?

Hello everyone, this is my first post. So recently I have been having a certain issue concerning my lockscreen bothering me. It really isn't a deal breaker, but it messes with my OCD. So at random times, the lock and message (life companion) on my lock screen shrink as shown in the attached image. It does not seem to do anything except for bother me. The lock screen does this unpredictably, but it does not do it often. I have tried a hard reset a few times and it does not fix it. It even fixes itself after a once again, random amount of time. I am not rooted, I use basic touchwiz, basically its how I got it out of the box with some games I installed through humble bundle. Any ideas?

It's a TW bug. It can also happen with the unlock "pad lock" icon that appears on the lock screen if you have no unlock effect enabled. It doesn't affect function and a restart fixes it. Happens to me maybe twice a month. Maybe it'll be squashed with the next official release. No biggie.

[Q] Random slowdown/WiFi freezing

Hi guys, hopefully someone can acknowledge if this is a common problem or not.
Basically when playing games (all games), does anyone get random slowdowns? Like the game becomes super laggy for maybe 3-6 seconds?
Using System Monitor, I don't see anything happening with the CPU such as hitting 100% or anything like that, so it's doesnt seem to be the CPU working on anything else. As said, it happens randomly but will always happen if playing. This doesn't seem to to happen in any non-gaming apps or the homescreen.
Secondly, another random issue seems to be toggling WiFi on. Basically when turning on WiFi from the Notification Bar, it will just sit there and then eventually the phone will freeze. I can still press lock button (on the right of the phone) which will put the srceen off and on as if it was locking and it even makes the locking noise. However the screen will be completely unresponsive, completely unable to interact with the phone.
Again, this is random and doesn't seem to be brought on by anything I can see.
Holding the lock button to restart the phone still works.
Running completely stock. (GT9190) on stock firmware for South Africa. No root, nothing.
So guys, does this happen to anyone else? Hopefully this is normal and will be fixed by Samsung with 4.3/4.4 or something.
S4 mini lags
I had the same problem but when i install New software update XXUBML4 it gone

Keyboard lag/touch input problem while typing

Does anyone's S6 edge have this problem where you are typing a text, at least 10 words long or more, and the screen don't recognize touch input just once, but it happens every 15 to 20 words? Its freaking annoying and I've since switched to the google keyboard and this problem don't happen as much, but the problem is still there, its caused me to misspell at least 7 words so far that the keyboard has auto corrected. This is so damn annoying and I hope I'm the only one that has this problem that way I can take this phone back and get it replaced.
I guess I'm the only one
Happens to me sometimes, but not all the time. It's probably a RAM problem. I usually clean/close some opened apps with Cleanmaster to prevent lag. Hope the next update will fix memory management problem.
I'm on Android 5.1.1 and it supposedly has fixed the RAM issue and the problem still exists. I don't think it's a RAM issue. I think it's a software issue that when you type too fast it stops recognizing the presses. Hapes mainly with the backspace key. If I tap that button like 20 times it will stop pressing it no matter how hard I press.
I want to say this is a Edge thing not a S6 thing.
Try a different keyboard from play store, also try closing apps in background.
I haven't noticed the ever on this incredible phone.
Running stock no root yet, with 3 pages of apps disabled.
Pp.
I apologize for resurrecting this thread but, I've been searching for a while with no avail. Since I've upgraded to 5.1.1 I've been experiencing this issue. Has anyone in the time of this thread found a possible fix for this?
I've tried multiple things, maybe going to have to resort to cleaning up with a factory reset.
This phone is so beautiful, yet functions like a POS, minus the camera. It just sits on desk collecting dust. I too have the aforementioned issue, along with dozens of others. First phone I've ever regretted buying.

Unresponsive display

I've gotten this problem since 20 days ago where my Google Maps get frozen in the middle of my trip. And I had reboot the device multiple times (4-5 times, sometimes skipping the LineageOS booting animation).
After fiddling over 2 weeks, I finally switched to LineageOS 17.0 now (previously using 15.1). The problem still persists.
The problem is : the screen froze, I seem able to tap something on screen but the display doesn't change anything despite my interaction with screen. This especially pronounced when I stop my screen interaction (i.e. not scrolling) on these apps
- Google chrome (say, reading any articles on web)
- Quora (especially when I about to scroll down on author bio)
- Google Sheets
- Maps
but this unresponsiveness doesn't appear at all when I:
- Play any kind of games
- watching YouTube (with the app)
In general, it seems anything that uses webview can cause the screen freezes if I leave it couple seconds. At first I thought changing from android webview to chrome webview implementation changes this. It doesn't.
The "cure" I found is simply turning the display off for 40 seconds ~ 75 seconds, and turning it back on, where I can interact with lock screen fine again. Any time lower than 40 seconds will simply show the frozen display again the time I turn the screen on.
Is it possible it's a hardware problem? (faulty RAM/storage) after using this for 2.5 years) Since full system wipe and re-install doesn't entirely solve the problem. The first time I encountered this is when I navigate with my Google Maps and the screen simply froze out during drive, and I had to restart the device multiple times, worrying that my device is broken. The next time I drive, I leave it only on Ambient Display and it didn't freeze at all.
So... any idea how to troubleshoot this?
It seems the problem is more severe than just Android.
Because even in TWRP, I noticed the display need to wait ~1 minute from the last time I turn off the display (push the power button) to reactivating it.
If I try to turn it on, the display will give black color, but I still can actually interact with the system.

Can you enable "Show Tap" option in developer settings and see if theres any ghost touch happening, sometimes ghost touch can "freeze" the screen while you want to interact with it

Thanks for responding.
I already enable "Show taps" on developer options. But the problem is that the screen freeze happened when there was no touch at all (i.e. I just looking at the screen, reading)
There's new observation I made today that : usually the screen doesn't want to immediately awaken when I just turn the screen off.
Today I tried to remove fingerprint from lock screen, the screen now is able to respond quickly again upon pressing power on button. It's still as responsive to power on when I add pattern to the device lock mechanism.
I'm not too sure whether this is OS level problem or even closer to hardware problem because this kind of unresponsiveness is also apparent even when I boot to TWRP.

That is one big weird problem, i've never encounter something like that since i ever using a smartphones.
It does really sound like, it just a software problem. But if it also happen in TWRP, it doesn't look like it.
I also have installed LOS17 by Arian before too, and i dont have that problem.
Sorry man i have no idea nor expert about it
It could be your battery is dying?, if your battery cant give enough power to the screen already, screen gonna act like crazy i.e ghost touch etc.
I have a broken battery been using it for 2Year + because of the battery my screen has a problem too. I replaced it last december 2019 and everything went normal again.

I don't think it's a battery problem. I see that I can play game for 1hr+ fine. A game that require exact timing of 2 touches on top of that. So that ghost touch really doesn't appear.
But yeah, it's really 2 contrasting sign
- In one hand, it seems an OS problem because I can simulate an environment where the screen definitely won't be frozen for hours, while on specific other environment, the screen freeze can happen very quickly between release and re-occurence.
- On the other hand, the problem seem doesn't stop on OS level because it can be found in TWRP.
If I read an answer on Quora that shows GIF image on the section I read, the screen freeze 100% won't happen. I tried the same thing on imgur too, the screen freeze won't happen.
So it seems that as long as the screen is showing dynamic content, it won't freeze (that's why game and YouTube doesn't show this kind of problem, but reading a web full of text/static images can)
A bit of update : I have left my phone in off state for 4-5 days. And I have been using it again, albeit, less extensively since my main phone has changed to K20 Pro.
Long story short : I haven't encountered screen freeze again. But this is just after 2 days playing with less intensity.
I wonder what really went wrong.
