If you aren’t looking for a kosher phone per se, Xiaomi is the best value right now. I have had a Redmi Note 4 for over two years with no issues, the battery lasts forever and the camera is decent. If you want a more “normal” Android experience, use a launcher like Lawnchair (it’s free) and it will feel more standard.
The Redmi Note 7 Pro has a camera that is almost on par with the top iPhone, and costs $250 for the top of the line model (coming out next week). You can buy their phones online from AliExpress, BangGood, GearBest etc.
