Sorry I accidently marked my last post on this solved but it is not solved:
So I bought a new samsung a71 5g from the tmobile store almost 2 weeks ago. Love the phone overall but the signal is getting me under 3mbps download and maybe 5mbps upload speeds in places by old phone was pushing 30mbps. Also the wifi calls drop all the time and then data service goes in and out. Here is a photo showing full 4g bars at Ontario airport for example and there is no network connection. Is this a known issue for this model, is there a fix coming? I am about to return the phone to the store honestly.
