[arunkumar]

Hello,
I am using Volla 22 Phone UT. The mobile data 4g L was working fine last one month, but from yesterday it was not working and i noticed wifi symbol is always appearing in network status on top. Screenshot attached for your reference. Please support me to solve this issue. Thanks!

Regards,
Arunkumar

@arunkumar Ok. So, there is no release change involved. Have you tried to reduce to a mono-SIM setup?

@sven Hi, now mobile data and wifi both connecting. Thanks!

I turn off the Wifi and remove both sim card, the first I insert mobile data sim card and then I turn on the wifi connection and off it. The mobile data was working immediately after wifi turn off.

But now i noticed few more new issue,

1. Wifi is not connecting automatically some times, when i enter wifi coverage. I need to turn off wifi and on again and the need to select the wifi network, then it working.
2. After connected to wifi, I unable to see which wifi it was connected, I mean its not highlighting wifi name.
3. Whenever I trying to take screenshots, Ubuntu Touch boot screen appear and going to home screen (lock).
4. Contacts search was not fast.
5. Bluetooth not working with my car. Bluetooth was paired perfectly, receiving calls in car but after answer no voice (in car and also in mobile) and also i dont know how to disconnect bluetooth and respond the call in phone. I need to restart my phone to make next call or receive calls.
