Samsung A51 Auto Brightness Bug? - Samsung Galaxy A51 Questions & Answers

Recently i just bought Samsung A51, it seems that whenever the auto brightness kick in, the setting is bugged, where the display will dim so low that the color of the display looked bleak. does anyone experience the same thing? or is it a defective unit?
The problem is solved if i restart the phone, but in a few hours the the display goes back to dim so low again. i've already reset the setting, and also do reset accessibility, but it doesn't seem to fix this problem. anyone have an idea to fix this? or do i need to go to the samsung service center in my town?

Galaxy A51 Have a lot of software problems

Hi, Please read my post in the link below
https://forum.xda-developers.com/galaxy-a51/how-to/problems-samsung-galaxy-a51-12-hours-t4042529

I have the same problem. how is it now? is there a solution already?

Sometimes auto-brightness not working for me. I've to disable and re-enable it to work it again.

Some working solution
Hi, i got same problem before.. it happens when we set the phone brightness too low or set auto brightness on when on bright environment..
Just simply wipe your partition cache and run graphics test...its works great for me.
To do that switch off your phone then press power button+volume up, choose to wipe cache partition then run graphics test..then reboot.

Recently, comparing the Samsung A51, it seems that always the automotive engine enters the air condition, the configuration is buggy, on the phone it is as secure as it is on the physical phone sombria. Alguém experimenting with the same thing? Or is it a union with defeito?
The problem was solved if I was rehabilitating the phone, but in some cases I was able to get a lot of security. I redefine the configuration and also redefine the accessibility, but it seems that this does not solve the problem. alguem tem uma ideia para concert isso? Or is it precisely for the Samsung service center in my city?

Screen turning itself off?

Just wondering if anyone has encoutered a problem with the screen turning itself off. It is not a settings issue but the screen randomly turns itself off in the middle of being used so i am guessing it mght be something to do with the light sensor perhaps?
Well if anyone else has the same problem or can offer some sort of explanation i would be very interested to hear about it.
Thanks in advance
i think this might be related to autolock. if you have that enabled, disable the screen dimming and let it turn off after say 2 minutes. then you should be ok.

I've had a similar issue recently - suddenly the screen started to switch off after 30 seconds without use, no matter what settings I configured in the energy system settings. No explanation, probably a bug in the 6.1 stock ROM. (I'm on another ROM now...)

Ditto.
Own ROM 6.1 (nothing special - really just Google maps and teeter removed)
Apps:
4 Column Start Menu.cab
FdcSoft TaskMgr 3.1.cab
GoogleMaps.CAB
GpsCycleComputer_3.114.CAB
htcAddicts cleanRAM v1.6.cab
MobileTweet.CAB
NETCFv35.cab
NetworkPlugin_1_0_30468_1.CAB
PocketShield.CAB
rar.ppc_arm.cab
SoftReset_Suspend.CAB
same here. tried some reg tweaks but none disabled poweroff after 30 seconds
it happens to me every time after i use igo8,
so my solution is to go to the MANILA power setting (not the default windows setting) and turn DIM off.
cannot find manila power settings. where are they?

i have Tom's 6.5 rom so when i goto regular settings it takes me to manila style setting & not the default one.
I have that problem to ?
I have a 6.1 windows, what can I do to deal with this problem ?
Thankx
in power settings enable & disable dim it will fix this but only till next time... i do it after every time i use igo8.
this is especially annoying when using the topaz as hard disk or navigating via tomtom. hope they will bring out a fix soon.
Think my problem was slightly similar as I was using the original shipped ROM. Well phone is with HTC now in for screen repair so hopefully the problem will be solved.
I'm guessing it was probably down to an install of some 3rd party application. anyway will repost after i get my td2 back tomorrow

Yes, I have exactly the same problem- auto brightness just doesn't work
- I can't find any more information about this on the web though. Anyone else with the same problem?

I did find one document on LG servers regarding on how to fix this. I will see if I can find it. It is hardware bug as I remember.
EDit:
I did not find that document but i found service software CD it has all, from hardware repairs to software upgrade. 512Mb

It isn't a hardware bug, i tested the proximity sensor in the hidden menue and it's working.
I fixed the issue when i wiped everything in the built in recovery and with everything i mean really everything you can wipe.
now i can change the britghtness to auto mode through the power-widget and it's working.
EDIT: before that, auto mode always turned full brightness on and i couldn't fix it
Brightness sensor still not working + pics and videos missing

Hi,
I tried wiping everything with hard reset/recovery - no change. Are you absolutely sure the sensor is working? I can change the brightness too in the power widget, but the screen still does not react to light.
Unfortunately I lost the pics and videos included when doing total recovery - I thought the built in backup would keep them (like it kept the pics I've taken) silly of me.... Anyone know how to get these files? Maybe a kind soul out there would like to upload them?

[Completed] Auto Brightness Issue on Sony M4 Aqua Experia

Hello XDA Dev, I am new here and don't know where else to go for advice.
I recently aquired a Sony M4 Experia Aqua (E2303 I believe) and the brightness is stuck on full brightness all of the time. I have tested to see if the auto brightness hardware sensor was still working and the values change whenever I cover it or remove my hand, so it looks like a software issue. I did a factory reset, reinstalled the OS using the software 'Xperia companion' and I still have the same issue - full brightness. I have however, managed to obtain an application that dims the screen brightness, it's called 'Night Mode'. It's sorted it out, so the phone doesn't burn my retinas every time I look at it in the morning, but I can't let go of trying to fix this. I have looked everywhere online, many people say they have the same problem, but they never seem to come up wth or find a solution. I really liked the adaptive brightness on my other M4 Aqua, I got this one as a replacement. I have a Samsung phone with a decent Android set up on it, so I wondered if I could transfer the OS from that phone to this one?

Greetings and welcome to assit. Unfortunately I don't think there is a way to transfer the os but you could install a custom rom from here
http://forum.xda-developers.com/m4-aqua/development
and see if that fixes the issue. Also there is an app called lux on xda/playstore that may help
Good Luck

Night Shot mode issues/crashing?

Anyone else having issues with the Night Shot mode?
It seems inconsistent in that it will either crash or produce a terrible low light picture.
Seems the following occurs for me (MHA-L09 stock firmware):
- load the camera app up and enter Night Shot mode, crashes (see pic 1 of it "processing") - though can see it is processing the low light and the image looks good, but it fails to process the image and save (also had to use another phone to take pic of it as was unable to screenshot it
- try and get back to the app after closing (clearing from memory) and cannot enter it
- reboot, open camera, take a few normal pics and then use Night Shot mode. Successfully captures and processes but the resulting low light image is terrible - full of noise! (see pic 2)
- After trial and error it managed to take a decent pic (see pic 3)
Pretty dam disappointed with this brand new device performing like this...
Hopefully an update could solve this?
Running MHA-L09C432B138
Are you using an sd card?
Try clearing camera data from app settings.

Hi, thanks for the reply.
I have tried both clearing the app data and not saving to SD card - just tried that now and it saved (didn't crash on processing) but saved a low quality 'noisy' image.
It's strange though, as whilst processing the image on the display looks great - it's the finished product that lets it down!
In night mode did you changed the iso or auto?
That's weird shouldn't be bad,all you can do is a factory rest and try.
If it's still noisy something is faulty,need a replacement.

Will try that for sure. I don't believe it's hardware fault, must be software.

Why you didn't mention that u have unlocked bootloader and flashed ur phone with funky?
Anyway did you factory reset ur phone from settings menu?

Regrettably I missed out that detail! I think at the time of writing then I had restored back and so regarded that as 'stock', but I potentially suspect that restoring with Funky MAY be an aspect....
I am tempted to do a full system restore with HiSuite with pure stock (non-Funky) and test that out

As far as i know hisuite wont work for non Chinese phones.
Do a factory reset from settings,with stock recovery installed,it will do a low level format, could be ur internal storage is corrupted and this can help.

Ok yes that's a great suggestion, will try that out!

I have the same problem. I'm on stock (MHA-L29C432B138), SD-Card or internal storage, same result like in OP.
Edit:
I noticed something. When I take a picture and it shows "in progress" and wait until the lockscreen comes and relock the phone, the pic is taken. Sometimes the camera is still enabled, sometimes it's closed
I tried the same with my Mate 8 (NXT-L29C432B560) , it's the same result.
Looks like it is a Firmware (EMUI/Nougat) bug..
I have the same problem with night shot mode but after change the animation scale to 0.5 in developer option the problem solved. before that i set to off. sorry for my english.

Hi, thanks so much! It works! :good:
Solved it thanks!
are you using HDR mode?
if so disable it, HDR mode makes low light look bad.

Excellent suggestion. It also worked for me! I also changed the 3 animation settings (Window animation Scale, Transition animation scale, Animator duration scale) and set the value at 0.5x and the camera is now fine.
Excellent, thank you so much!!
Thanks so much! I'm new here, signed in just so I could say thank you since this solved my camera problem. Anyone have opinions after owning the Mate 9 for a while? I just got it to replace my Nexus 6P with battery issues- not sure I love it yet.
I'm amazed how well smartphone cameras in general, work, given their size.
A typical 8mp sensor, should be able to print an A3 (11x17) image, but who prints anymore?
They keep placing more and more sensors in these things. More megapixels, typically is only
good for crop/zooming. Increasing the sensors can sometimes backfire because the signal to
noise ratio (crosstalk) increases due to the very small spacing between signal paths.
I wish they would just increase the SIZE of the sensor, put a real 5-10x optical zoom lens on the back
similar to the non phone Samsung Zoom a few years back. But with the trend still that phones have
to be "slim, sexy, colorful & stylish", don't see that happening.

Mi Note 10 weird screen issue (ghost touch?)

Hi all,
Just got this Mi Note 10 today and while setting up the phone I started to get those weird screen touches..
Happened so often that I enabled 'Show Taps' via developer options and recorded it here:

>> Is there anything I can do about this? Not sure if this is a Hardware or Software fault?
Any thoughts welcome!

Okay, this is weird. Which version is it? And did you have already tried to reset your device? If it's still there it's probably a hardware defect.

Right, so no fix really... disappointing as the cameras are impressive
My device came shipped with Android Pie Based Miui 11, no screen weirdness. Just after the Android 10 updates that ghost touches appear. So I guess it's just software bug.
me too, sure software problem.
Thanks for the feedback, if software-related were you able to roll back to fix this?
Happy to try a workaround as I'm very reluctant to send it back..
worth a try though, but unfortunately Xiaomi didn't provide stock ROM specifically for my region so I left with no choice
Completely puzzled as I did a Factory Reset via Recovery and haven't seen the issue for past 2 days, I've left the screen touch tracing on and no 'ghost touch' was recorded..
so I don't know what to believe anymore, got an open return ticket but would hate to send it back without needing to..
how can I make sure issue is gone?
Hi, i had this problem 3 weeks ago, temporary solved with hard reset, worked perfectly until yesterday night when this problem went back.
Hard reset again, problem still there.
Someone solved it permanently?
It is really weird because, if i turn off/on the display, sometime works sometime not :S
The phone came with Android 9 and I started to face this after updating to Android 10. The issue is not extreme as shown in the video, it just the touch becomes slow to respond and hard to type fast with the keyboard. Turning off the screen and turning back on solves it temporarily sometimes.
I tried disabling on screen fingerprint and the problem seems to be reduced now. Definitely a software bug
I'm using Mi note 10 lite it also has same problem. Sometime touch freezing and after press power button automatically fix. Some time need to restart. And also one person told me he is fixed by this issue by turned off fingerprint sensor.

I have the exact same problem as you, slow to respond and hard to type. Need to apply more force on the screen for it to respond. This happened randomly throughout the day but are more common during night time for me.
I think it has something to do with the screen lock pin or fingerprint, by changing the screen lock from ie pin to pattern or turning off fingerprint print seems to temporary fix the issue. Another solution is to reboot the phone. I'm using Note 10 Lite btw.

I am using the Pro version. Looks like this issue is common for all the phone models in the Note 10 series. Yes, I have noticed that this issue often happens at night.
Try switching off MIUI optimization under Developer Options and restart your device. Then switch it On and restart again. This workaround solved my issue.

This fixed the issue for a few days and it started to reappear again. When the issue appears, if I turn on Game Turbo for any app (eg: WhatsApp) that particular app doesn't have this touch issue. Looks like a software optimization or battery optimization of MIUI is causing this issue

What firmware version are u in?
I'm currently at 11.0.16.0 and fortunately this issue did not yet reappeared after the workaround.
This is definitely a software ISSUE with MIUI.

Will try out the MIUI optimization to see whether issue still arise. I'll see if my game turbo have the same issue as you too.
I'm currently at 11.0.7.0 (Mi Note 10 Lite)
Edit: Mi optimisation doesn't work for me but the Game Turbo trick do work.
