Dear All
I have recently bought in Vivo V9 and done a system update days ago. My current Android version is 8.1.0 and software version is PDF1730F EX A 1.10.7
Following are my two questions/problems:
(1) Whenever I make a call, phone will vibrate when the call is answered by the other party. How to disable this vibration? I cant find any setting to disable it. Under Sound and Vibration, I have disable the Vibrate function but still the issue persists.
(2) After the update, there is no more LED indicator when I plug my phone to wall power supply. I have activate this: More Setting/Blinking Indicator and Flashlight Notifications, but I still cant see any LED indicator whenever I charge my phone.
Hope you all can shed some lights into my queries.
Thanks in advance for any input.

(1) its not under sound and notification.. its on call alert under call setting
(2) no idea...sorry cant help on this... i dun own vivo acctually..

Vivo and Oppo is a crap brands, lousy built quality, buggy software and etc.. even cheaper Xiaomi or Asus still better. suggest change better phone.

Xiaomi or Asus have GPS problem. SamSung bundle with bloatware.
It hard to get better phone.

That why android can't beat iphone, IOS softwares more stable, second apple built their own chip much better performance, even faster than high end snapdragon series.
