Is this an issue with just getting signal or some kind of network/cellular error message when using a certain service? We have ways to fix this if it happens but I don't see we've gotten any known issue with general connection problems.
Unfortunately not, I did a JOD upgrade from a Note 9 to XS MAX and immediately noticed a dramatic difference in LTE signal strength. I am hoping they iron this out soon but I am starting to believe this is an issue with the Intel Modem in the devices with the issue being so widespread. I would hold off for now, unfortunately for me I am past my return period =(
