Xiaomi is currently working on the Nougat update for their MIUI 8 OEM skin, and they need some help from the community. If you own the Mi Note Pro, Mi 4c or the Mi 4S, then you can apply to become a beta tester directly on their forum.
The Samsung Galaxy Note 7 isn't the only phone exploding. The Xiaomi Mi 4c was also said to have exploded and caused 3-degree burns in one case. It doesn't seem to be a widespread issue like the one Samsung is dealing with, however.
I was trying to find out about this Chinese phone the other day, trying to find out what the pros and cons were and from surfing the net through lots of different web pages and forums i came to the conclusion that the Xiaomi Mi4C is a very good phone for the amount it costs you to buy.
