I am using m35 for 2 years & p4x for 4 months the p4x is very good than m35. It has lcd but smoothness & 1000 nits display couldn't feel that is lcd. Its a very good phone but now the prices increase so not worth it.
Samsung software & everything is good except the processor & the line appeared on screen.I think samsung willingly give a update to create a additional cost on customers
