When on phonecalls through the phone can hear like a computer beeping noise like when on a computer when a new notification comes in. Not on bluetooth or anything else. No timer or anything specific on settings on phone but happens a lot since last update. Gets annoying and I dont know what is causing it or how to fix it.
When this happens there is no call waiting. Its not a call waiting beep which I am familiar with. Its like a computer page opening or closing, or a computer notification sound. Nothing to do with call waiting or call timers etc.
