i have an android game that runs so smooth on low screen sizes but when i run it on phones that have big screens like galaxy j6+ or galaxy A5 the fps drops down. please help and sorry for my bad english
Try to optimize your game, if you use shaders, then a higher resolution screen needs more computation
Then you probably maxed out the Fillrate of the device. You may have some shaders which have expensive fragment shaders and you may have expensive post processing shaders. Of course any shader that works on the actual pixels / fragments will be heavily impacted by larger screen sizes. Try to avoid the Standard Shader if possible. Like xxmariofer said, you should do some profiling. Unity has countless profiling tools, use them. We can’t profile your game for you.
