Why can't my phone find my TV?
Short answer: Nine times out of ten: the phone and TV are on different networks (guest WiFi, 5GHz vs 2.4GHz band, or a VPN on the phone). The fix is putting both on the same network — here is the checklist.
An empty scan almost always means the phone and the TV are not actually on the same network — even when you think they are. Run this list in order:
- Compare network names exactly. Phone: Settings → WiFi. TV: its network/about settings.
HomeWiFiandHomeWiFi-guest(or-5G) are different networks on many routers, and guest networks usually isolate devices on purpose. - Turn off your VPN. A VPN routes the phone's traffic off the local network; scans see nothing. This one catches everyone eventually.
- Get off cellular. Remote control is local — WiFi icon on, not LTE/5G.
- Wake the TV. Recent sets respond in standby, but a TV switched off at the wall (or a stick that lost USB power when the TV turned off) is unreachable. Power it on once, wait ~30 seconds, rescan.
- Check router isolation. "AP isolation" / "client isolation" blocks devices from seeing each other. Home routers: it's a setting, usually off. Hotel and apartment-building WiFi: it's usually on, which is why remote apps rarely work there — a hotspot is the workaround.
- Platform-specific refusals. A Roku that appears but ignores presses has "control by mobile apps" disabled — a one-setting fix.
Remote Pro scans all four platforms at once (Samsung, Fire TV, Android TV, Roku), so if any controllable device is visible on the network, it shows up. If the WiFi itself changed and the remote is lost too, you're in the catch-22 — here's the way out.
