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!
