Sony is very good company.
Having this phone with me since last 2 and half years and is in good condition. Phone works smooth and fast when apps are not installed.
Battery back up is good but the phone starts to lag once apps installed are more than 10.Camera quality is worse it, woould strongly not recommend this for camera lovers.Phone does not have 4g which is a big letdown.Screen is 4 inches and fits in the pocket perfectly.Call quality is good and signal is good, Would advice to consider other options as android version is jelly bean and is outdates.
