White circle appearing when button on phone app is touched.

Have a 16 Pro running 26.2. Around the time I installed 26.2 I noticed a white circle appearing when I tap certain buttons when making a call. It disappears after a second. Photo attached.

This issue shows up only when you’re connected to a Bluetooth device. During a call, switching the audio to your iPhone, speaker, Apple Watch, smart watch, or Bose SoundLink can cause the handoff to stumble. First, disconnect all Bluetooth devices and test again. If the problem continues, forget the third-party accessories—especially Huawei watches, which are known troublemakers in this department.
