I have been using the phone for past one year and I would say I am disappointed with its performance. The phone is too laggy and the battery life has reduced to only 8 hours support. Even sometimes the phone gets hanged and doesnot open for a long time.
Games like temple run 2 also has low frame rate. I would not recommend anyone to buy this phone. Though the features were given but the company has not customized the OS for the proper use of the features.
