S8 ignores screen timeout preference and goes to sleep in seconds

[userbytXeG6wNM]

So I just got my S8 yesterday, so far in love with it. However, the topic at hand is really bugging me. I'm used to turning off my screen manually, or at least having it wait for me 5 min before is goes to sleep. On this phone I have it at 15 min but it still sleeps in 6 seconds. I even tried downloading a third party app that is supposed  to disable the screen from sleeping unless I do it manually or turn off the app, but it still sleeps on me in 6 secs. I don't have any power saving features on, nor do I have smart stay on. Please help.

Have you tested in Safe Mode to see if it still happens there at all?

I just finished testing that and yes, it still happens.

Try clearing out your cache partition, and then re-adjust your screen time out settings. Let me know how that goes.

How do you clear cache partition?  I can get to screen that let's me either restart, factory reset, safeboot, or shutdown. Cant find clear cache...

Hello. I had this same problem , guessing you just got it? I even got a replacement phone and still happened. The problem is some where in when you restore phone from one of your accounts, like Google account or Facebook . What I had to do was a clean wipe, DO NOT restore your phone from a back up, just do a clean boot, then link your accounts and just go to your Google account and grab you contacts and do apps Manually . This should fix your problem.. or at least did for me

Thank you so much! Not only did it fix the screen timeout thing, but it also help with the constant Wi-Fi "authentication problem I had!

THAT'S CRAZY TO DO A CLEAN RESET AND THEN TO RELOAD ALL THE  APPLICATIONS MANUALLY.  DOES THE PHONE APP GET RELOADED WITH RESET? I'M REALLY TIRED OF HAVING MY PHONE APP TIMING OUT IN 5 SECONDS AND LOCKS THE SCREEN THEN PRESSING THE POWER BUTTON TO UNLOCK THE SCREEN IS A REAL PAIN IN THE 

BUTT. THERE HAS TO BE ANOTHER WAY TO FIX THIS WITHOUT RESETTING THE PHONE.

Seriously! Can Samsung not deliver an update that fixes this automatically??! This is really annoying.
