I purchased this mobile for 15000 rs.Mobile is good in functioning never observed lag or hang issue.but even in this price important sensors like auto brightness, fingerprint, gyrometer are missing.nd most important if u want use jio sim u cant because it does not support VOLTE.spending 15000 with no 4G is not good option.I suggest you go for MI redmi note 3.wonderful mobile with great features in just 10000 and 12000 rupees.i like the amoled display and slimness of E5. Battery is not that great if you are a heavy user than it will not last 24 hrs.camera is average.
Final thoughts -dont go for it
