1. Brand. Any except for AP ( warranty issues)
2. Budget. <1.2k
3. Specs. >2gb ram , 5~5.5inch (coming from N2)
4. What you need in the phone Snapdragon 800 and above ( if possible) or mediatek which can compete. Good build , battery and speaker , having SD card is a must . Use mostly for browsing and gaming ( removable battery is a +)
Currently eye-ing on a few Redmi note 2 , Find 7 .
-Hope sifus here can give suggestions for more option
