So few days ago i upgraded my S6 to android 6.0.1. Right away i noticed that my Lock screen and home screen wallpapers were changed, i didn't think much of it and i set the old ones back, no biggie. I don't know what happened later but i had to restart my phone, i did that, and i was greeted with the default wallpapers, again. I set the old ones back again thinking it was a bug or something. A day later, i decided to check if the problem wasn't persisting, so i restarted my device, and yes i guess you know what happened. Same scenario. I was recommended installing a launcher, but it didn't fix anything really. Does anyone have a fix to this? i looked around different forums and i saw people experiencing this issue but nobody got a fixed answer. I know its not a serious problem, but it can get annoying sometimes. Thank you.
