1. Brand. Anything
2. Budget. 1k~1.2k
3. Specs. Larger than 3.7 inch,
4. What you need in the phone : Decent sound quality, solid body (not those if slipped from the hand will get heart attack kind) not laggy. I wouldn't mind AP sets, smooth internet browsing, smooth UI. Decent gaming capabilities, would last long (More than 3 years.)

Thanks.
