H818P Speaker wierd problems

Hi to all! :)
Help me, anybody please! The problem with small (front) speaker. This make some noise (click-click-click). :(This sound plays anytime, even in sleep mode, when display turn off. Reboot didn't helps. When android starts, noise start playing too. BUT, sometimes noise disappears, when I use my G4, and appears again later. Firmware I use Lollipop 5.1 10d+root. I try to uninstall root and go to restore backup system.img via cmd to stock. It wouldn't helps. I think the trouble is in some system app, that always forces front speaker to work. Also this clicks (noise) can be listened very loud, when you record video in stereo (stock camera for example), and then play video.:crying:

Can you advise me, how to resolve it, please?

H818P data settings

Is there any app out there or can make switching for data between sim cards easier or to control data usage for when you hit your limit it can switch over and possibly with Auto switch rules. Would be a great addition to this phone. ?

Or if someone can make a widget to switch between it also would be good .
