I have been using this phone since 2.5 years this is the slowest phone I have ever seen do not go for this . This hangs a lot RAM and internal memory are not sufficient in this era to much hang I m not satisfied I faces this problem many times .
The only solution I have found is the restore factory setting. Remember to save your essential data prior to reset. worst phone battery drain very slow process there in nothing in my phone memory than also it shows internal memory full notification worst phone very slow & hang many
The biggest issue of this device is sometimes it missed incoming calls and by that way I have several important incoming calls and the callers had to contact me by an alternative way .
