Recently my Note 8 having signal dropped/ Network disconnect for no reason.

I need to restart phone to get back the signal. It will happen again maybe few hrs later. So annoying. I went to change a sim card and the problem still there. Is this a software bug? Never happened before. Only recently.

Today is 19 September 2020. Problem coming back. No network signal. If I don't check then no one can contact me. Scary phone. What is wrong with the phone. Leaving last choice to master reset it. If problem still there then I need to say bye2 to Samsung. Phone life just 3 yrs old... Lesson learned.

After master reset it. Completely unable to connect to network. I think hardware problems. TQ
