I have been using this phone since 1 year, never got any issues.but the weight is some what heavy to manage but it is comfortable to hold and use.battery is very good, it stays for 1 day for moderate usage.rear and front cameras are perfect in this price range.glass is protected by corning gorilla technology which is six times stronger than a conventional glass.viewing angles are good.speakers produce 3d sound effect while watching movies.nice one to use.
