F_Christian_Persson_ydbE, Oct 31, 2018 : I've searched around the forums and Google and I've found similar problems but it doesn't match mine. I bought a car stereo a while ago from Wish.com to be able to stream music via Bluetooth. Everything worked perfectly until just recently the Bluetooth started to stutter for unknown reasons, it's like someone is scratching a CD while the music plays. So I tried my dad's older Samsung and another android phone, and it works, so it must be mine that's the culprit. I think it happened after the Android Pie update recently, but I am not 100% sure. I think it worked for some time after the update. Things I've tried: - Changing the Bluetooth codec on my phone to like LDAC or aptX, but it won't change to what I choose. I guess it's because it auto-changes depending of what Bluetooth device I'm streaming to. - Every other Bluetooth device works, like a speaker or headphones - no stuttering there. - Tried finding a firmware for my stereo. No luck though. It's from Wish, so what can you expect... Anyone else have the same experience or know any solutions? My best guess is that it's a codec problem.
