I have a new S10, upgraded from an S8. On the S10, I cannot answer calls from the locked screen. The green and red telephone buttons appear, that you are supposed to "slide" to answer or decline calls. I press on these icons, but nothing happens. They do not work. Any suggestions?? Seems like maybe a software/programming bug.
did issue started as soon as u got the phone?
do you have any theme applied on to ur phone?
also, what carrier are you using? and can i have your software version? you can find it at Settings -> About -> Softare Info -> last 4# of Baseband verison
can you test it on safe mode please?
do you have call recording app by any chance?
