Every time I open an app on my appradio, I get a loading picture (for approximately 1 or 2 seconds). The picture is a random picture from my phone, which I never selected. I have no clue how it ever got in the appradio since I never selected anything like that.

Since a few days, the loading screen has a picture which is quite disturbing to have on my radio for everyone to see. I tried to change it, but I can't. The picture isn't even on my phone anymore, but it still displays every time in open or close an app.

I tried the wallpaper in the appradio app, changing the wallpaper in the settings menu of the radio, but nothing works. I even completely removed the appradio app, still no change. How do I remove that picture from my radio?

Thanks in advance.

Since there are five appradios out now, it's hard to pinpoint which one you're talking about.  I'm guessing it's an 01 or 02, but I'm not the best at mind reading.

It's the Appradio 2 (sph-da100).

I tried resetting the appradio, but the picture is still there. Must be on my phone or something, hidden in some app maybe. I think I'll have to restore my whole phone.. (iPhone)

I'm afraid you're correct.
