From yesterday I got some wierd sound from my Galaxy S9+ baseband G965FXXU5CSF2
Whenever Ive locking screen or unlocking I get 4 beeps sounds, about 4-5 seconds between each other. (Weird sound not one of the notification sound selection)
I have tried the cache partition wipe, turning off notifications, Safe mode (still beeping), NFC and Notification Reminder OFF but it hasn't stopped these beeps!!!
It seems I tried everything I found online
please help me
Let's try a soft reset on your phone. This will end all processes and give the phone a fresh start. Press and hold the 'Power' and 'Volume Down' buttons until the phone restarts itself.
Let us know if this makes any difference.
