Hello everyone I have AT&T as my phone carrier and I have dropped calls if I called somebody more than 2 minutes the calls drops I contact Samsung told me it's AT&T support contact AT&T AT&T wants to blame for Samsung I think this has to do something with it January security patch update are you guys having the same issue dropped calls delayed text messages on your Samsung Galaxy s20
update I did a factory reset 10 minutes ago and I'm still having the same issue I think this has to do something with the January security patch update both AT&T and Samsung cannot figure out what's going on is anyone else having the same issue is anyone else having this problem
I would try a network reset From settings > General management > Reset > Reset Network Settings BEWARE THIS WILL UN INSTALL YOUR WIFI AND BLUETOOTH DEVICES AND AFTERWARDS YOU WILL NEED TO RE INSTALL YOUR WIFI AND BLUETOOTH DEVICES I'm with Verizon, and had the same problem. I did this and now I'm good to go But if the problem still persists then I would replace your SIM card, have AT&T "reboot" your phone and before you leave try it out
I have did that multiple time reset network settings a factory reset I even took out the SIM card I think it has to do something with the January security patch update
I have repeated issues with my phone stating not linked to a network. I use my wifi calling most of the time because I have no cell service at my house..I don't understand why I get repeated notices about this. when it comes up I cannot make calls and persons calling me go right to VM...took the phone back to att store where I purchased it, they try to say it has to do with the mobil security app I has loaded...I say has to be something else because it should not be continuing to happen.
I have ATT currently but it really doesn't matter who my carrier would be because of my location. there is a tower less than a mile from my house and I still have zero service. I'm pretty sure its due to living in a mountainous region as there are many locations in my state that have zero cell service
I also should not get any kind of notice since my phone has wifi calling capabilites and I have business class internet speed literally sitting less than 3 feet from my router.
