I have a Samsung galaxy A20 that has been working fine for the few months I've had it. But last week I received a system update that has now rendered my bluetooth basically useless. It used to have a 30 foot bluetooth span, and now it disconnects if it's even more than 12 inches away. I use my bluetooth every single day and I cant explain how frustrated this makes me. I tried restoring factory settings, but that did nothing. And when I chatted with a Samsung worker online, I was told I need to take it to a service center. If Samsung screwed it up in the first place with an update, then why the hell cant they fix it with an update...
