I also have some random stuttering problem when playing game (hill climb & ski safari). I've not had any lagging issues with the phone itself in general usage. But have concerns that the phone needs to be replaced but don't know if anything is wrong or just something to live with....
I made sure power saver mode is not on..and also running NOVA Launcher.
Sorry in my ignorance I don't know how to post pictures of benchmark test...but it came out "12094"
I would really like to know if something is wrong with my phone to replace or how to further test the phone for problems...hate to do it cause of the Spigen Glass screen protector that is on will be lost...lol
