MOBA games performance drop

with this specs. why moba games like mobile legends, Arena of valor and vain glory are very lag? can someone know how to fix this?

Have a look at all the apps you have installed. Uninstall some that you hardly use.

How to find out which apps you use most:

- open play store

- goto menu in upper left corner

- tap My apps & games

- tap on tab Installed

- sort on last used

I highly suspect erasing an app or two and releasing memory will do any good in this case.

Either the specs are not optimal for games, or the games haven't been optimised, maybe for Oreo or in general.

Try installing them on similar specs phone, compare Antutu scores on both phones, and you will narrow it down. 

Most likely, if only those games are affected, it's on the game devs to do the heavy lifting.
