I'm having the same issue. I don't use any 3rd party apps to set the do not dossier and it was working until today. I'm drinking an s20fe. I Sry it up through switch from an a05. It was fine. It works fine on my old phone. It was working fine until just now too. The ink my thing that's different from the other day is that I've put my Sim back in my old phone because I'm returning the s20fe due to poor LTE signal compared to my old phone. I get poor signal already where I live but is not as bad as this s20. I boughtt it refurbished on Amazon. Also the battery isn't as good either, considerably so. And I don't use it any differently either. Another issue is with biometrics. I have to constantly redo my finger prints. And it's not due to dirt either. It work fine on one thumb but it only works for maybe an hour or two on the other. I make side to use all sorts of orientations and positions too. It's driving me nuts. I only upgraded because I needed to have nfc for something. Besides that and it being quicker to boot up my a05, oh and the richer colors, but for everything else my a05 is better.
