So the phone is going to be used for only the following things:

  • Paytm (Accepting payments from customers)
  • Showing customers pictures of cakes (so screen size & quality is the highest priority)
  • Whatsapp

Thinking to get the Xiaomi Mi Max, any other suggestions?

Is there any good tablet which'll do the above too?
