The advantages: - The price - The trick "standards" (android and everything that follows ..., 4G ...) The caveats: - The bad camera (eg, QR code are a little fuzzy and hard to see). - The battery, as most smartphones, to recharge every night if you use it a lot - The time a bit longer charging only on high-end smartphones, but it's still very good. No regret having bought it anyway, very good deal
