I dont know why Samsung called this as an major upgrade with no system app updates,battery worst management,long app launching times,nothing but just adding profile icon on the seetings app,i dont know what is the major difference 8.0 and 9.5 Samsung...
lol that's the Samsung ui feature i mean launcher,that persists since Touchwiz kitkat,it happens after a long usage,it is not been solved by samsung folks,it can be resolved by a factory reset
