I am also having the same issue. Samsung should fix this issue ASAP. It is causing me so much trouble. Everytime the network stops I have to restart my A50. Most of the times the signal bar is stuck at one. I didn't have this issue in my samsung A5 2016 model. Even calling other people has become troublesome. Please solve this issue.
I am having the same issue. It is giving me so much trouble. Every time the signal bar is stuck at one. I am using Vodafone network. Everytime I try to call someone the call doesnt get through so I have to restart my A50 everytime. This issue didnt happen in my previous samsung A5 2016 model. Samsung needs to fix this asap.
Same here. It is fixed changing connection to 3g in one sim and 2g in the second sim. With 4g signal drops very low, unbelieveable that samsung ships this phone in this way. We are not your beta testers.
Same here. I purchased A50s on Oct 31st. From day one it is not able to catch 4g network. They flash the OS but no use. Now they said change motherboard. It obvious that handset is faulty and should get replacement.
