My S8 searches for wireless networks, but doesn't find any. They are there and my S20 sees them all. The S8 can be told to look by the square barcode thing that came with my router but doesn't connect. I've talked to EE and they couldn't help. It's not the router, it's the phone. I've tried the tips on Google but nothing works. I get the spinning icon to say wireless is searching, the it switches off, then on again for the same result. I've cleared the network settings etc but nothing changes. I may need a factory reset but can't remember my Google password for my old email address, help I'm ok mostly with tech but am in a corner withe this phone I want to give to a friend.
its not the WiFi. I've done a factory reset and with the camera , focus on the barcode square, it seen the network name and password, message said connecting, but nothing seen. it looks like there is damage to the phone internally
exactly a 2017 phone is old. coming up to 4 years old. maybe try wipe cache partition or factory reset it.. s8 is a good phone (was) but its a bit old. I give you a tip. If things don't work correctly. wipe cache partition if no joy factory reset. Then ask in forums.
