[Samsung Galaxy S10 Questions & Answers] sainthooligan:
Lol, sorry to see everyone busting you up on this....because you know, it's always more helpful to give someone a bad time to ensure a post count increment, than to be useful and offer up some insight.

Well, I have had screen burn in occur on 3 different galaxy phones. Not from falling asleep, not from being clueless...but from using my phone with games. 2 were mine and 1 on My wife's..hers occurred from youtube.

I used to play clash of clans tons, got burn in from the smaller stats numbers at the top- over time...But replaced the phone no sweat. Verizon insurance took the phone as a defect, noted as screen image ghosting, no charge. I just didn't realize that it was an issue playing, but it was over time. I think it was an s6. The reps in the store were as surprised as I was that it had occurred.

Different device & model, S7 , but same thing occurred, not in the same game either...This time with clash royale- the towers and little cloud icon burned in from too much playing and too often, apparently. I thought I had been a bit more careful, but i think it was the frequency in which I was playing versus overall time.

This time I simply contacted support in the chat about the ghosting, they replaced it again as a defect, no charge.

My wife's occurred on the s7, hers was the top bar because of YouTube, too much & too often. So, did the same for my wife's phone through Verizon insurance, they replaced as a screen ghosting defect.

After I noted what was going on, she made adjustments, didn't happen again to either of us.

Both of us are on the 10s now and very aware this can occur. So, you just need to make sure you're not on those static images or bars or icons for either long periods or frequent shorter periods...it takes time, but it happens, despite popular misconception.

It is only really noticable on a white background, like when looking at mostly blank new tab in chrome.

On the last device, the S7, I made sure to cut the amount of time spent on static images, especially the games. I still kept the brightness always max during the day, nights it was at the lowest setting.

And yes, I kept my settings the same after the replacement, just made adjustments to my gaming approach. I didn't want to baby the phone screen settings, shouldn't have to. No issues on that one after adjusting my approach.

So, it's certainly possible to avoid and I bet there's many out there that use certain apps for long periods and frequently just do not really notice it may have occurred, even if slightly.. and I'm taking heavy users.

A note app with a clean page or white blank background reveals it, most of the time you're not using that, so ignorance is bliss...and makes It's easier for folks to bust on someone else for asking about screen burn in because they themselves are simply clueless it even remotely occured with them.

Heavy user naysayers, check your old phones, just for the heck of it... and then keep the findings to yourself because no one actually cares about you being right or wrong.

Anyway, it was an inconvenient lesson at the time,for me but good to know and learn from. Didn't cost me much but time, as it just took up time set up the phones again.

I know Samsung isn't too concerned about it or they wouldn't have preinstalled games on the phone (ie. solataire).

Just do your best to adjust your screen settings, like those that mentioned, if you're into that. Or simply adjust your apps/usage habits.

Don't overlook the Digital Wellbeing settings on the S10...that may also help you target certain apps with a timer also. Might be something useful for you.

Hope that helps some.
