Samsung Galaxy Tab A6 Android OS has a mind of it's own
 

I have a Samsung Galaxy tab A6 with Android os. This thing has a mind of it's own. if i hesitate for even a few seconds, it will open random apps or tabs, or even try to access the internet. if I shop on Google app store, it will randomly open apps there as well. My question is, How do I fix this, and/or replace the OS to something else? Thank you in advance.

I know what you mean. I have the S7 edge, and it's similar.

get busy once, and control this - leave an hour or two for this.
Samsung packages EVERYTHING - it's own fancy junk, piles of crap you don't need and competition in the form of 'Galaxy Apps' 'Google Apps,' IM facebook, twitter, blah <long list>

1. Settings/Notifications and Disable everything you don't want to hear from.
2. Settings/Apps and uninstall or disable everything you don't need; You will be lead through uninstalling updates, etc.
3. Repeat steps 1 & 2 for everything that still pops up/crashes/notifies, and repeat until the thing shuts up.

You ACTUALLY DON'T NEED 2,000 messages a day from people you don't know, you can survive without viewing scores of inane videos from losers and dweebs, and the world doesn't cave in if you never read another blog. Why sift through 2 Gigs of <&£%$@!> to look for 100 bytes of readable intelligence? Life went on before television, and it will go on after. Keep this in mind when defining what's needed. If there's something worthwhile, your friends will tell; you and give you the link. Their time wasted, not yours. The internet is a time thief.

Thanks! I'll give it a try!
