Phone need restart before playing game

[AC Question]

I am playing Vainglory game and before I start the game I need to restart my phone. Why ? Because if I don't restart it, my game second before starting crash and then log in again and everything is normal. So when I restart phone before playing, I am able to play 3-4 games, after that same problem. My phone is galaxy s3 (not rooted), 4.3 android. I asked developers of the game and they told me to restart phone also.

Is there any other way (or any app) to fix this problem ? I supposed its because of active apps. I tried to close them manualy, but it didn't help.

Welcome to Android Central! Do you have any "RAM booster/optimizer" apps installed? If so, uninstall them, and see if that helps. Those kinds of apps can actually cause more problems than they purport to solve.
