I made a worst decision of buying the lenovo A6600 because the phone lags, it simply lags, the sound is so low that it gets hard to hear the ringtone in public places even the earphone sound quality is not so good the bass is flat. screen is bright but does not give wide angle view even the UI is not so good as it lags and when I installed too many apps the touch freezes as it is bundled with only 1gb ram, the phone is sleek but have very low material built as it is made of cheap plastic even screen gets scratched easily. the phone comes in marshmellow but has very low battery of just 2300 mAH, since the body is made of plastic so it is not durable, the phone comes cheap and supports 4g with 16gb of internal storage so it is value for money phone but the features are very low.
