Hi as im using this mobile from since three months its performance was good but it lacks to play videos then every time I have to restart the device and its size was not good to hold without a pouch as it is slippary in our hands the main problem with the device is it will overheat some times while charging and most of the untrusted apps will make the device over heating so guys be carful of that, it comes with 3.0 fast charge and the battery backup was amazing and the features like blue light filter was pretty cool to use in night to avoid effect on eyes more over I had tested its waterproof and it was good and it will give you on screen notification when it detects moisture in the charging slot, to clean it, over all the device was acceptable and the price was a bit high.
