How Phone Remote Controls Actually Work on Sharp TVs
Most people find out about controlling their Sharp TV from a phone because they lost the actual remote or it stopped working. The good news is that Sharp TVs support this natively on most models from 2018 onward. You do not need to buy anything extra. There are a few different ways to do it depending on what you own. The standard approach uses the built-in Wi-Fi remote app that comes with most Sharp Android TV models. You download the Sharp Remote Control app from the Play Store or App Store, connect your phone to the same Wi-Fi network as the TV, and the app finds the TV automatically. From there you get a full directional pad, channel buttons, volume, input switching, and a working keyboard for searching. It replaces the physical remote for everything except special functions like picture mode toggles and some menu navigation, which still require the original remote or a workaround.
Sharp TV Remote Control Your TV With Your Phone The End Of Lost Remotes
The second option is using your phone's built-in IR blaster. Some Android phones like older Xiaomi and Huawei models have a small infrared transmitter built into the top edge. If yours does, you can use apps like Mi Remote or Sure Remote to program it as a Sharp TV remote. This works even if the TV is completely unresponsive to Wi-Fi commands because it bypasses the network entirely and sends raw IR signals, just like the original remote would. The catch is that your phone needs that hardware. Most newer flagships removed the IR blaster, so this only helps if you have a specific phone model or an older device lying around. I ran into a real problem last year when my Sharp LC-55LE650X lost Wi-Fi connectivity after a power surge took out the router. The phone app was useless because it couldn't reach the TV. I tried every troubleshooting step including factory resetting the TV's network settings twice. Eventually I pulled out an old Xiaomi phone with an IR blaster, installed the Mi Remote app, pointed it at the TV, and it worked immediately. The IR approach does not require any network connection at all. It is completely independent of your Wi-Fi setup, which is useful when the TV's network stack acts up. For Samsung phones there is a separate route through SmartThings. Samsung includes a TV remote feature inside the SmartThings app that supports many Sharp models. The setup process is similar: same network, auto-discovery, then you get a full remote interface. The advantage here is that Samsung tends to keep this feature updated longer than third-party remote apps. The disadvantage is that it is locked to Samsung devices. If you have an iPhone or a non-Samsung Android phone, you are using the Sharp app or an IR solution instead.
One thing people consistently get wrong is assuming all Sharp TVs support phone control. They do not. Models before 2018 mostly used proprietary Sharp remotes without network-based control options. If you have one of those older sets, your best bet is a universal IR remote or buying a replacement Sharp remote from parts suppliers. The model number is usually on a sticker on the back of the TV or printed on the original remote's battery cover. There are also limitations you should know about before committing to this approach. The Wi-Fi remote app has a noticeable lag compared to a physical remote, usually around 200 to 400 milliseconds. For casual channel surfing it is fine, but for fast menu navigation or gaming it feels sluggish. Battery drain on your phone is another factor. Keeping the remote app running in the background while you watch TV will use roughly 5 to 8 percent of your battery per hour, which adds up if you watch a lot. Another issue is that some Sharp TV firmware updates have broken remote app compatibility in the past. A few users reported the app failing to discover their TV after a software update rolled out. The fix was usually to reinstall the app, toggle the TV's network settings, and sometimes downgrade the TV firmware if Sharp released a known-bad update. Keep that in mind before doing a firmware flash on a TV you rely on for this setup. Keyboard input is another area where the phone remote falls short. On-screen keyboards on Sharp TVs are notoriously slow and finicky. Typing a search query through the phone app feels better than using directional buttons, but it is still slower than typing on a laptop or tablet. If you stream a lot of content and search frequently, consider pairing a Bluetooth keyboard to the TV instead. It costs about fifteen dollars for a basic compact one and solves the typing problem entirely.

The IR blaster route, when your phone supports it, is the most reliable fallback because it does not depend on anything besides line of sight. Just make sure your phone is pointing directly at the TV's IR receiver, which is usually a small dark window near the bottom edge of the bezel. Angle it too far and the signals bounce off walls and fail to register. Aim it within about thirty degrees and you are fine. Range is roughly six to eight feet before you start losing reliability. If none of these options work for your situation, the last resort is a dedicated IR remote app paired with a cheap external IR blaster dongle that plugs into your phone's charging port. These cost around ten dollars on Amazon and give you IR control on any phone without a built-in blaster. They are not as convenient as a native app, but they work universally across Sharp TV models and brands.
