Comments on Button Mapper: Remap your keys for Android
★★★★★Riko Rey· Jul 17, 2026
for peopling with phones that have the traditional bottom-3 physical navigation buttons; this is a must-try. It makes using swipe navigation on these phones viable by allowing you to bind single tap to nothing (so if you swipe nav and press it, the button doesn't register)and opens up their use for custom binds with double and triple tap. That's 6 extra custom macro key binds materialized out of nowhere, more if you fw the volume keys! Good perf makes this a 5 stars experience

Fixes the audio playback issue on spotify, I've had a problem that I'm sure I'm not the only one having, with single button wired earphones on spotify, since Spotify doesn't recognize three clicks to play previous songs, and the long press enabled the assistant, so I could only skip to next, but now with this app I can remap the earphone buttons to do anything, so I made it to allow a long press to play previous instead of it using Gemini, and it works!

Does what it is expected to, the only nuance is that when I customize zello ptt on vol up or down long press, it continues until held again. The zello ptt on the main options screen works flawless, but it's both vol up and down, thus taking away my settings for single double and Long volume presses. If we could separate the main settings screen ptt to allow ptt vol up and a separate setting for vol down, this would hands down be the best app out there.

Love the app, I've been using it for years. The latest update 4.07 seems to have an issue with the flashlight toggle on LG V60. I have the assistant button mapped to toggle flashlight with long press and after this update it only turns the flashlight on but not off. Same issue after switching it to single tap and double tap. I've also tried restarting my phone, restarting the app and reinstalling the app including adb commands but the issue persists.

Wants a billion permission and special settings that you're left on your own to figure out. I enabled all accessibility buttons, but it still won't work and won't tell me how to fix it. Not worth the heart strain.

New button mapping worked one time only. After that even the mapping existed it does not respond. TCL Bluetooth remote.

Useful features locked behind a paywall, I just wanted my volume keys to control my media volume during a call, greedy app developer wants 10+$ for this feature. Use key mapper it's free and works better than this copycat app. Also, this developer is very sassy, so I'm giving one bonus star to my original review for that.

Stopped working on my smart TV after reboot. NOT a samsung tv but TCL using Google TV
