Having same issue wit Note 9+. Slow to load apps say I have a ow internet connection. Can't make or receive call when signal level is at 2 bars or less. Same issue with second phone.
Wow, I ordered an unlocked Note10 from Samsung.com and I tried two carriers (VZ & T-Mobile) and I've had weak signal or no signal at all in the places where I previously had no issues. Thank you for this! I thought I was the only one. Get it together Samsung, at first you release a phone that doesn't have a language keyboard and now these phones are experiencing a weak signal.
