I have wondered about this matter in the past week and a thought struck me today. Could this strange phenomenon have anything to do with the Samsung Galaxy S23 Ultra Smart View Wallet Case that I am using for my phone?
I know it lets me access interactive display on the phone without opening the cover and uses some kind of technology to achieve this. I have never considered it affecting the phone in other ways, but I am beginning to wonder if it actually plays a role here.
To test it out I played the same song 2 times today, first with the case/cover closed (like I usually listen to music on the phone) and this phenomenon happened again, the end time of the song disappeared for a while. The second time I had the case/cover open so it did not cover the front of the phone and I could see the Poweramp display with the song all the time, this time the phenomenon did not happen and the end time remained throughout the song. I tested with a second song (MP3) to see if it might have been a glitch the first time but the exact same happened again.
I therefore suspect that the Samsung Smart View Wallet Case on the phone somehow interfers with the Poweramp-display. Could be I am wrong but I find it suspicious that it happens as described above.
If anyone else has this Samsung phone (or other model) and also the Samsung Smart View Wallet Case and could test it, that would be helpful.
Thanks.
