I am using this phone for three years and it has got absolutely no problems yet. It has a 1.5gb ram which is enough for its normal usage. Though it has a 2600mah battery but it has a remarkable battery life. When the device is locked it dosent consume even 1% battery overnight. The back camera quality is good but front camera is satisfactory with only 1.9 megapixeles. It has a feature of one hand operation of the phone basically becuse the size is not comforable for one hand use. I am very much satisfied using this phone and want to recommend this phone.
