Samsung S3 Screen keeps flickering

[Beverly Coker]

I beg your pardon but it was EXACTLY because of that. I followed what Abilash S advised & that fixed the problem! I turned off the developer options & I have not been having anymore problems. Obviously, Abilash S knew exactly what he was talking about!

Everytime i try to check my messages or press menu for it to come on, the screen remains black, then keep pressing the middle button it lights up but turns off very quickly, it does not allow me to check anything.

i went to settings, but i dont see Developer options, can you assits with this?

Reasons for folifolicking

I figured out what caused my screen flicker.
Hope this helps.
My symptoms: screen would start flickering and then i would get a black screen. All other functions work just could not see anything. Turning phone off and restarting would give me about 30 seconds before the screen would start flickering again.
Cause:
My phone got exposed to a magnetic field. Something in my phone got magnetized . In my case, a power drill at work is what did it.

Solution:
I let my phone sit. Power off for a day. And the flickering only started after 2min. So i let it sit for a full week. It has not flickered since. This was 4 months ago.

Phone model :Samsung galaxy s3
But i can imagine this could happen to all kinds of phones and models.

Lots of things in our world can create a magnetic field!!!

Hello. I had my phone disassembled for 1year and I just bought a new digitizer because the screen has broken at that time.
While I was assembling parts I noticed that the pieces that I have taken from the phone had some magnet force.. The screws were "glued" to the several parts of the phone i had stored in a bag.. So I think maybe you could be right about this.. What I notice is that when I let the phone on, but in standby, and then when I turn it on, the flickering is better and slowly starts to become worse in 1min..

I just started having screen flickering problems in the last 2 days. I have had my s3 since 2012. I figure it's gotta die at some point. I have installed so many different ROMs, Recovery's, all kinds of weird stuff. Rooted, developer options...you name it. Best phone I've ever owned. I guess if it keeps up I'll need to switch back to my galaxy s1

Re: Samsung S3 Screen keeps flickering/flashing.

Yetserday out of nowhere my samsung S3 screen started to flicker (it's like lines on the screen all the time moving). I've tried rebooting I even bought an anti-virus.... I have no idea what's happening it won't stop. Any help?

I disabled auto brightness in the pull down menu.

Same problem @FabianaMCC had. Some white lines move on screen then the phone reboots. I have custom ROM - Lineage OS 14.1 and custom kernel - Boeffla latest. Through the zip, I disabled all the kernel configurations and did not helped. Maybe it is problem of battery too, because in powered off mode (when charging) battery STILL shows 69/70%, if powered on (only for few seconds-minutes, then screen flickers and phone restarts) it shows less then 10% and in TWRP it shows some random amount of % (once it was 0, once 80...) I was not doing anything before this started happening. I consider buying a new battery, then I will write here if it solved the problem. Thanks for all help.
