OK, I need some help with this one because its driving me crazy. Here's the deal. When I add a Lockscreen Notification app like HiLocker, Next, Picturesque, Echo or any of them, when I get a Voicemail and click on the Voicemail Icon and hit play, as soon as i move the phone to my ear the Voicemail stops playing and the phone locks. I have tried all the above mentioned, same result. I even did a Factory reset trying to fix it. I'm using a Galaxy S7 model SM-G930V Android Version 6.0.1. If I use the stock lock screen, which I hate, I don't have any problems with the Voicemail. Any help or advice would be great. Thanks.
