Hi, my Samsung Galaxy S7 Edge has no radio signal. No bars at all regardless with SIM card inserted or not. I believe it’s a hardware issue. What controls this? Is it the antenna cables or the antenna brackets?
Have you checked for Blacklist / IMEI issues? If not, go to the website - https://www.devicecheck.ca/check-status-… It says Canada but is valid worldwide. I would check before even disassembly my phone. Good luck!@
