Hi
@Darkvaper Thank you so much for reaching out. Can you please try to troubleshoot your SIM:
Put the SIM card from SIM1 to SIM2 to check if SIM 2 slot has same issue
Put another SIM card to SIM1 slot to check if issue relates to SIM card
If this this does not help, I recommend that you visit your nearest service center.
As for the Ultrasonic triggers, can you clear the cache by going into:
1. [Settings] > [Apps & notifications] > [See all xx apps] > (upper-right three-dot icon) [Show system] > [AirTriggers] > [Storage & cache] > tap [CLEAR CACHE] and [CLEAR STORAGE].
2. Then, access [Settings] > [Advanced] > [AirTriggrs] > [Preferences and touch settings] > [Ultrasonic buttons settings] > (retry)
Thank you!
