Ok after digging the web in a few days, found that the devices with the mali400 GPU has this issue. Xperia e4 and LG g4 stylus has mali400 GPU. Tried on xperia e4g->Mali-T760MP2, xperia Z5->Adreno 430 GPU,casper via8 tablet->Mali-T720 MP2 GPU everything is fine. in my country many people uses economical or cheap smart devices, like me So that in 2016 already some devices uses mali400. isnt there any solution for that?
