I appreciate you trying these steps with me. It sounds like we would want to try backing up the phone and testing with a factory reset. But I know that's a pretty drastic step to take and people are mostly reluctant to do that. Heck, I would be. So before trying that I just want to double check something with you - what do you currently have your Display Settings adjusted to for the screen timeout option?
Currently it's set for 10 minutes. When I first noticed the issue, after turning the phone off & removing the battery the first time tech support suggested it, and just after completing your suggestion to clear at my partition I have tried literally every available option in that menu to see if it makes any difference, but it has not. If I had a convenient way to back up everything on my internal storage, this wouldn't be such a pain in the ass. Since I don't, I'm going to have to get rid of some things I truly don't want to on my SD card, just so I can make room for before I can even do the factory reset. Then, I get to experience the pain in the ass of a completely different flavor that is the process of trying get my phone exactly the way it was (the way I have it now, minus the problem that I've been trying to resolve since literally the first day I purchased the phone of course) before I fixed the issue the phone never should have had to begin with. So, Samsung, thank you for nothing. Before this incident, I loved your products. I was literally smiling giddily with anticipation and excitement when I brought home my current phone, bur having to go through all this without any recourse or or compensation makes me wish that I had just gotten an LG or even an iPhone instead... 😡
So after some internet browsing, I came across an article about this issue and they suggested downloading an app called "stay alive" on the Google Play Store. I downloaded it, and it is keeping my screen on. It sucks to have bought a phone that needs a third party fix...
My phone is the Boost Mobile Samsung J3 Emerge with Android 6.0.1
Set the screen timeout display
15secs 30secs 1min etc to what you want....stay in the display screen and restart the phone....there is no need for 3rd party apps to keep the screen timeout on..regards..keith
