I am having a very annoying problem. It is now hit and miss when i get my text messages. I can send a message and sometimes it's sent right away other times hours later. Receiving text messages is the same way. It does not matter what messaging app I use they all do the same thing. The only thing that works...sometimes is rebooting the phone but that doesn't always work. Or sending messages from my pc, which means I'm tethered to it pretty much. And that gets very tiring and cumbersome. I use a Galaxy Note 8 and it was working perfectly until i had to send in my phone for replacement due to a charging issue and i've had the issue on two replacements because I thought it was a phone issue. I would really like this to be solved, I can't contact clients or hear back from them reliably with this issue going on.
