Issues with Liberty 4

Hello All,

I used to own a life note 3i and very happy with the result. However I moved to Liberty 4 and now facing some major issues…

  1. The liberty 4 TWS fails to recognise my siri command with the first try, when I try it for second time in a row- then it pick up my command properly.

  2. During a incoming phone call, I dont hear any ringtone at all, this is pathetic.

  3. The mic quality is supposed to be better than life note 3i however I experienced like the other party struggles to understand my voice properly- sometimes it is good sometimes it is bad- no consistency actually!

How to fix these issues? Please help me!
