Samsung software is frustrating

After recently updating my Samsung S23 from Android 14 to Android 15 with the latest One UI 7, I've started experiencing several frustrating issues.

Previously, if I was on a call and an alarm was scheduled to go off, the phone would only vibrate silently in the background. Now, the alarm rings out loud even during a call, making it difficult to hear the other person. Worse still, I’m unable to dismiss or snooze the alarm while on the call, which causes a lot of disruption.

Another issue I'm facing is with saving contacts shared via WhatsApp. After saving a number, it often doesn’t appear in my contact list or when I try to dial it later. This makes it feel like I’m running in circles trying to find numbers I’ve already saved.

These issues are quite frustrating and significantly impact my daily use of the phone.
