Comments on Button Mapper: Remap your keys for Android

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.

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

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.

Installed because I needed to map a button that wasn't volume, was told to pay for it, uninstalled. Don't list your app as free when you need an in-app purchase to turn it on. Just charge for it, save both our time.

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

The power on/off on my Galaxy Note is broken plus I hate the Bixby nonsense so I uninstalled all Bixby apps via adb. Wanted to use this app to remap the now vacant Bixby buttons to toggle on/off the phone screen. These app allows you to toggle screen off but not on again - eh?? Yes you say when screen is off phone cannot respond to button presses, but you should find a work around since remapping off/on seems the most logical use for this app yet; no support!!
