Just a mistake to buy such a bad phone.storage is very low. Sound quality is fair. Screen resolution is fair. Hanging problem. Style and design is not good. Features is very low. worst phone main software problem is not good I m using so many phones but in my life sony xperia e3 phone is number one worst phone please no body purchasing e3 phone.You can’t use 4gb. U can use only below 2gb. But u can move some apps to sd card and can save some space in internal. I can’t erase any photo or video from its device. If I delete something if would be appear again. So I can’t download new game or video for insufficient storage! . So plz never buy this phone.
