I thought you used bigger objects. however a programmer who created a guide for Android said to use 60 fps with v sync, I did it and it worked. if you try to do tests and a combination that will not give problems with sliding objects (bullets, obstacles), just tested, at 50 fps (with sv sync) etc. stuttering is very heavy, especially with the "every x seconds" events for the creation of objects, both on my new phone and on the pc and if I remember correctly also on my old phone, it only works on a one of my telephone 50 fps phone. instead with 60fps it works very well.
