Friends,

I have one more slight problem with this phone ie.Xiaomi Mi 4i that the phone has very low volume, I sometimes miss lots of calls because of its low ring volume. Kindly suggest what can be done to solve this problem ?

Dear Rohit, are you using some sort of phone cover or protector, then make sure it is not closing speaker in any manner. Also, you can try updating your phone if you have not already done so. What is version of your MI 4i software ? You can check that in settings and phone and then software updates..
