I am using this phone for one year now.
I am a heavy multimedia user and I can guarantee you a full day battery.
No lags and if paired alongwith a memory card is an excellent option to start with.
I never felt any problem with this phone.Im a professional engineer, So, I installed upto 100 Apps.still the phone didnt get strucks or irritates.Im using a 8GB SD card in it.Inserted a AirTel and JIO SIM cards in it.I receive frequent Software Updates for this phone which will improve the performance of the phone and reduces the Heating problem.The only problem was that it has a low 2000Mah battery, So, I recommend this phone for those people who are looking for Budget phone.
