Hiii friends, I recently purchased my new Xiaomi mi 4 mobile two months ago. The mobile was absolutely good. No heating issues. Except when we play a lot of games it heats. The phone never hangs. It is a super looking mobile with great features. The fingerprint scanner is also very fast 0.3s unlocking. The mobile gets miui 9 update very fast. Camera and other features are also very good. Proud to be a owner of this mobile. If anyone wants to buy a mobile my best suggestion is buy mi4. Thanks guys for reading my review.
