I have been using this phone since 8months.till now no problem are seen.the phone is great with many many features.the only highlight of phone is its attractive price.the phone is packed with 3gb ram which is pretty much cheap as compared to samsung or apple or htc.so overall very good phone with nice features and apperance.the perforance of phone is also very good.if u wana spent money on mobile in the range of 10-13 then this is the good option may be.thanx guys.
