I bought this mobile( 2gb version) from ebay few days ago. After using it for a few days I found that it can’t be used as a primary phone but only as a spare phone.
My mobile has lot of lag and it hangs on doing a bit of multi-tasking. It also has heating problems, and heats up alot while charging. Even the battery backup is poor. The touchscreen responce is slow and the screen quality is not good. Camera quality is very bad especially at night. I feel that the overall quality of the mobile is poor.
I would recommend spending some extra money and buying redmi note 3 or note 4 instead of this mobile.
