Xiaomi is big brand in mobile market, especially in India it’s number one mobile brand. People loves to use xiaomi’s product because it’s feature rich and cheap. Except 1–2 players, nobody is selling phones with high feature and low price as compared to xiaomi. That’s what make them big brand.

Xiaomi owns one of the best android UI skin- MIUI.

MIUI is my favourite Android UI- Except bloatware and lots of ads 😠

MIUI has lots of bloatware and annoying ads that drastacally harming user experience. That’s where some phishy things happens. There is one (useless) system app called Clean Master (under Security app) which is used to clear your unnecessary files (look’s like Android itself is not taking care of this things 😄). Now you will ask, what is wrong with it as tons of cleaner apps are available on Play store. But the things here is, it’s developed by one of the most notorious company on play store known as Cheetah Mobile. They are infamous for collecting lot’s of user data and selling it to ad provides. Here’s what their official site says about ads :
