I got my sony xperia z1. When I buy this smartphone I have 4.4.4 kitkat on that os its works fine but on other side it say new system updata avabilable so I updata it after updata it change into lollipop which is bad. I want to play my old games but cannot run my games and which games it can run its too lagging like amazing spider man 2, the dark kinght rises, gta san andreas and etc.
But on kitkat its will runs fine. On video recording quality is perfact photos capturs by it is clear and highe quality and the most owesome feature is it can support 4K videos on 60FPS ( Frame Per Second) .but it is a 3G smartphone it cannot give 4G net connection.
