This is an excelent phone by moto camera clarety also so good if u want to buy any phone below 10000 better to choose this one and its not hanging and other problems
For camera on 5, for battery e3, performance on both phones is same because of touch Wiz from Samsung and stock Android from e3 Moto. Performance can be expected as same, but it’s better to go for Moto e3
It is always recommended to do a factory reset after the update to clear out the cache to achieve max performance.
