A lot of people have several remotes in their homes. TV, streaming box, soundbar, and AC, each with its own controller. Often times it's either these remotes get misplaced, fail when you need them, battery got weak or it gets completely spoilt. 

And most times it's not easy finding a matching replacement for the lost or spoilt remote therefore you'll be forced to operate your TV and gadgets from the buttons on its body. 

As for me I wanted a cleaner setup, so I added a simple option to my routine, using my Android phone as a central controller. It saves time, reduces clutter, and works alongside the regular remotes. This guide shows you how to set it up and use your phone to manage TVs, streaming devices, older electronics, and home gadgets whenever your remote gets misplaced or gets spoilt, or the battery is dead, or may be you want extra convenience.

1. Know How Your Phone Connects

There are three common ways your phone talks to devices. Use the method your gadget supports.

Method	How it works	Requirement
Wi-Fi or Bluetooth	Controls Smart TVs, Roku, Chromecast, Fire TV	Phone and device on the same Wi-Fi network
Infrared, IR	Works with older TVs and AC units	Phone with IR blaster, or external IR adapter
Brand apps	Official apps for advanced functions	Install the manufacturer's app from Play Store

2A. Control Your TV and Streaming Devices

The steps vary by device type. Follow the right path for yours.

I. Smart TVs

• Connect your phone and TV to the same Wi-Fi network.

• Open the app, scan for the TV, and pair using the on-screen PIN.

Apps to try.

2B. When Your Phone Lacks an IR Blaster

Many phones no longer include IR hardware. You can add it with an external adapter. The adapter plugs into USB-C or Micro-USB and acts as an IR blaster.

3. Expand Control to Home Gadgets

Move beyond TV control. Use a single smart home hub app to link lights, plugs, speakers, and thermostat.

Example routine, Movie Night.

FAQ

1. Do I need a Smart TV to use my Android phone as a remote?

No. Smart TVs work over Wi-Fi, but older TVs also work when you use an IR blaster or an external IR adapter.

2. Will this setup replace all my remotes?

You can still keep your remotes. Your phone gives you a faster and cleaner option, but it does not stop the original remotes from working.

3. What if my TV does not show up in the app?

Check that your phone and TV share the same Wi-Fi network. Restart both devices, then reopen the app. This fixes most pairing issues.

No. Only phones with a built-in IR blaster or phones that support OTG with an external IR adapter can send IR signals.

Yes. You only need network access or IR control. Your phone does not store sensitive TV data. Stick to official or trusted apps from the Play Store.
