My wife's S22 and my S22 ultra often don't respond to a single finger tap to navigate, initiate an action or enter a response. It can be dangerous when operating a vehicle using my phone as a gps. But now I think the root cause it's related to the quality of service. I have poor signal quality at my home so I've been trying different signal boosters. I notice better signal quality gives better screen response to taps of my finger. I have had poor signal quality for 16 years and many different brands of phones but I've never had a problem with the touchscreen not responding properly. I turned in an error report and Samsung says they know about the issue. I hope they prioritize user input when the phone gets busy looking for signal. It will lead to less distractions while operating a vehicle and less frustration while using their flagship phone. I would think the screen working properly would be top priority when releasing new hardware/software
