Usually I just swipe up, but on this phone instead of having a proper icon, it just says answer in green on the top line at the right hand side. If I touch this the answer button disappears. The call continues ringing and there's no way to answer it .
On my previous phone an icon showing the phone ringing showed until it was answered
but what happens if you just touch the answer call button? on my phone, the answer call button disappears and the call carries on ringing and I have no way of answering. Another Samsung modification to stock android? I have two other phones and that never happens. it only happens on my Samsung if I am using an app. I reckon its a bug.
Found the problem. If you look in call display while using apps, there are three options. Full screen, pop-up and mini pop-up. All these are only effective AFTER a call is answered. If you just try to answer a call by touching but not swiping the answer button the call is not answered so these popups don't show. on all other phones, the red and green decline and answer buttons do not disappear until a call is answered properly. This is definitely a bug in the 3ui system. they should be an option fir phone calls to display over other apps, or to be always on screen. I cannot find one. can anyone else, and if not how do I complain directly to Samsung.
it's still not working, but may perhaps since the new system update today. Also the screenshot method of using power off and volume down doesn't work. or if it does there is no notification where its stored. if I swipe across the screen tge the shot is stored in gallery .
