Bars decrease in the same location as the day goes by, only in one location, eventually no data.
At the beginning of my day at my office, my S22 Ultra (same exact problem with previous phone, S21 Ultra) has 5GUC and has blazing fast speeds with four bars. This is at my desk. My desk does not move. My building is not mobile. As the day goes on, the "UC" from "5GUC" drops. Bars start dropping. Eventually I only have one bar and sometimes only 4G. The data speeds drop from blazing fast to no data connectivity. This issue does not seem to affect voice calls. This issue happens daily, and is consistent across two different phone models and multiple devices. I have spoken with customer support and they stated that there was some modernization being performed on the tower that I connect with in this location. That was several weeks ago. At some point the support tech made some unspecified change, remotely to my phone and the bars increased and the "5G UC" returned to my phone and so did the blazing fast speeds. That only lasted for a few hours and the issues returned. I don't have time to sit on the phone with customer service all day because I'm at work. Does anyone have any advice?
