UMI Z no sound and no connectivity [fixed]..

crazynilesh

Hello there....
Sometimes you get no sound from phone and restart is the only option to fix it.
You can prevent this problem to occure again and again......after you restart your phone follow the steps given below.
1. If you have installed any third party optimizer software, just remove it. It is actually the clash between third party optimizer software and the optimizer which is inbuilt makes your sound driver gets blocked and there is no sound in your phone.
2. Go to  setting>battery>battry optimizer>all apps. Make all apps not optimized which are linked to sound.
3. Sometimes connectivity is also gone, so unoptimize all those apps linked to internet like whats app, gmail, etc.

Hardware is absolutely fine. Don't worry about it. Its the optimizer which blocks your drivers and apps.  
You will find the performance also improves, your phone works faster.

The only problem is battery drains 5% faster. I hope UMI will fix this problem in next update.
Its solved my problems and hope it solves yours too.

Thanks & Regards,
Neal.
