Thank you, sounds pretty much like my conclusion so far.

Any comments on camera comparison? That's the thing she would like the most.

1. Brand.

Any local set.  But no brand like eleephone or leegoo

2. Budget.

One is  around(400 to 600) plus or minus
and another one (600 to 800) or a bit more

3. Specs.
Can use USB otg, microsd,  removable  battery, 4g

4. What you need in the phone

good signal reception and WiFi reception, as good selfie as it can be for the price, not laggy if use lots of apps, reasonably good camera, gaming not much only games like candy crush
