I have a Samsung Galaxy S6 mini, it's an quad-core running at 1.4Ghz and has 1.5gb of RAM. It's an ok phone, I don't know if it's just me but the battery life is very subpar, sometimes it last around 12 hours at best. I have played some PSP games on the emulator and it's fast, same with games like asphalt 8 airborne, all of them run without problems. The camera it's great, max resolution is 8mp and it records video at full hd resolution. My only complains are the battery life (maybe I got a defective unit), and the screen resolution.
