Your Phone as a YouTube Remote for PC

https://play.google.com/store/apps/details?id=com.droidactor.bt_remote

You start a YouTube lecture on your laptop, lie down in bed, and notice the captions are off. So you walk back to the desk. You raise the speed to 1.5x, lie down again, and an unrelated video starts playing next. A wireless mouse does not help much, because the pointer barely moves on a blanket.

If you watch YouTube in a PC or laptop web browser, every small change sends you back to your seat. Dotori PC Video Remote is a YouTube remote app that turns an Android phone into a Bluetooth remote. Nothing is installed on the PC. Play, speed, captions and the next video become buttons on your phone.

The features sit on three tabs at the top of the app. The Play tab handles play and pause, 10-second jumps, captions and fullscreen, one button each. The Speed & List tab changes the speed and moves to the previous or next video in a playlist. The Mouse tab turns the phone screen into a trackpad so you can pick the video yourself. This post shows how to control YouTube from your phone, starting with the connection. Then come the three tabs, help and settings, and the limits to know first.

Your phone connects as a Bluetooth keyboard and mouse

Dotori PC Video Remote registers the phone with the PC as a standard Bluetooth keyboard and mouse. The PC simply sees one new keyboard and one new mouse. That means no driver, no companion program and no account. One Bluetooth pairing turns the phone into a PC remote for YouTube on a laptop across the room.

Each button sends one of the YouTube keyboard shortcuts as a key press. Play and pause is K and captions is C, keys YouTube already accepts. There is nothing to set up on the PC. The app shows each connection stage in order. The stages are HID registration, pairing check, connection and a minimum report check. If something stalls, you see exactly where.

A PC that connected once is saved, so the app reconnects to it right away next time. You can also switch to another PC from the connection history. There is no app login and no developer server behind the connection.

The Play tab switches captions and fullscreen with one button

These are the buttons on the Play tab and the keys they send.

Button	Key sent	What happens on screen
Play / Pause	K	Pauses or resumes the video
Mute	M	Turns the sound off and on
Captions	C	Turns captions on and off
Fullscreen	F	Switches to fullscreen (exit with Esc)
Theater Mode	T	Shows the player wider
-10s / +10s	J / L	Jumps back or forward 10 seconds
-5s / +5s	← / →	Jumps back or forward 5 seconds
Volume	↑ / ↓	Raises or lowers YouTube volume

When you miss a sentence in a lecture, go back a little with -5s. Skip a long intro with +10s. For a foreign-language video, keep YouTube captions on and turn the sound down. The phone's side volume buttons also change YouTube volume.

Speed and the next video live on the Speed & List tab

YouTube playback speed changes one step at a time, faster (Shift+.) or slower (Shift+,). The app's Speed + and Speed − buttons send these keys. So you can set a speed per video: fast for a lecture, slow for following a workout. The Prev Frame (,) and Next Frame (.) buttons step one frame while the video is paused. Use them to freeze a single hand movement in a cooking video.

If a playlist is playing, the Prev Video (Shift+P) and Next Video (Shift+N) buttons move through it. For a lecture series, you no longer find the list and click the next video each time. A large Play / Pause button stays at the bottom of this tab as well.

Pick what to watch with the trackpad on the Mouse tab

A YouTube remote with only buttons cannot choose another video from the recommendations. The Mouse tab turns the phone screen into a trackpad that moves the PC pointer. Drag to move, tap to click, and use the scroll strips along the top and right edges to scroll. If you open the wrong video, the Back button (Alt+Left) takes you straight back. That shortcut follows Windows browsers.

Picking a video and controlling playback sit on separate top tabs. You never scroll down a long screen hunting for a button. Use the Mouse tab to choose and the Play tab to watch.

Watching one lecture from bed, step by step

Here is how the three tabs work together for a single lecture video.

1. On the Mouse tab, move the pointer and click the lecture. This click also makes the YouTube window the active window.
2. Switch to the Play tab, press Fullscreen (F), and turn on captions (C) if you need them.
3. On the Speed & List tab, raise the speed a step or two.
4. To hear a missed explanation again, go back with -5s on the Play tab.
5. If the lecture is part of a playlist, open the next one with Next Video (Shift+N).

Help and settings cut down the routine

If you forget which key a button sends, open the help (?) screen in the app. It lists the keys for the Play tab and Speed & List tab buttons on one screen. The same keys work on the PC keyboard, so they are handy when you sit at the desk. The app interface comes in Korean and English.

If you mostly use one PC, turn on "Connect to the last PC on startup" in Settings. The app then connects when it opens, and you do not pick the PC again. The same Settings screen turns the phone volume buttons for YouTube volume on or off.

Three things to check before you start

1. It only works with YouTube opened in a PC web browser. Other video sites, desktop media players and the YouTube app on a TV are not supported.
2. The YouTube window must be in front. Key presses go to whichever window is active. If a chat window is in front, K is typed into the chat. Click the YouTube window once on the Mouse tab first.
3. Your phone must support the Bluetooth HID Device profile. It also needs Android 9.0 or newer. On some phones, power-saving policies can end the background connection.

One more case follows from the second point. If you clicked the YouTube search box, the shortcut keys are typed into it as letters. Click an empty part of the page before you use the buttons again.

The app shows one banner ad at the top of its screens. Key presses and mouse input from the phone go only to the PC you choose. They are not sent to the developer. YouTube is a trademark of Google LLC, and this unofficial app is not affiliated with Google.

Wrap-up

Dotori PC Video Remote makes your phone a Bluetooth remote for YouTube on a PC. It covers play, speed and captions, and the PC needs only a Bluetooth pairing. You pick videos with the trackpad and control playback with buttons.
