This is best phone by Gionee in budget. Build quality is good for price.
Procceser is MT6739WW 64-bit with 2GB ram and 16GB internal storage which is expendeble upton 256GB. Perfomance is not good but you can play some higher games like Asphalt 8. The most amazing is that you can play PUBG in low graphic setting.
Display is 5.45inch HD+ . Display quality is not bad.
Back camera is 13MP which is not bad and front camera is also ok.
Battery ( 3000Mah) so you can use this phone for one day without charging.
All speks are good for this price.
