iPhone 7 -Distorted notification sound
Since few months now I experience distorted notification sound (sms only) on my iPhone 7. It occurs randomly (let say 50-60% of cases). It sounds like my phone tries to play notification sound for 6-7 times in row . or at once (for one massage) but each attempt of playing notification interrupts already played notification - like a cascade of 6-7 sounds at once - sounds awful!
Since than there was at least 2-3 iOS updates which I have installed but nothing changed.
Can some one help?
