Im a samsung and sony xperia guy.I took the risk to buy this phone because it has 20 mp front camera, 32 gb internal and 4 gb ram plus.Im impressed with the secondary camera, beauty face shots are very natural looking unlike other brands where you look like you have a foundation make up.I was prompted by system update to new version and performance is still smooth, no lagging issue at all.No battery heating issue even if you play games, browse internet or download.But if your looking for a better performence for games , you could go for xiomi mi 5.Depends on you.
