Hello friends, xiaomi mi4i is really good product. I am using this product from last one year, and I am fully satisfied. Camera quality is also very good. This product have many interesting features. Mi4i camera is better than xiaomi note 3. The xiaomi mi4i is powered by 1.7ghz octa-core oualcomm snapdragon 615 processor and it comes with 2gb of ram the xiaomi mi4i is a dual sim( gsm and gsm) smartphone that accepts two micro sim . But the problem is we can’t call with jio sim in this phone. But we can use jio net. So good luck.
