Comments on KeyLinker for Android

★★★★☆ DRG197 _ · Jul 8, 2025

With zero instructions, after some fiddling around, I got my NYX Hyperion 2 to show and was able to configure them the way I liked. I had to have them powered, and not paired as joy cons, they have 2 connections shown for each joycon, for a total of 4 separate signals, so it's easy to get mixed up. Once you have them set up, it's easy to just have them on, open the app and select the one I want to configure. Also, have nearby device permission on, then disable when not needed.

Fantastic app. I have read some of the other reviews already, and maybe my experience is holly different, was having problems with my controller, tried everything (except taking it apart) this app fixed that entirely, helped a great deal, can change the colors, brightness, and other stuff which seems Allright and doesn't seem broken, the app does have an effect on the device and works fine for me. Great Nintendo Switch device and great app to compliment my glowy in the dark controller. Love it

I use it for machenike controllers and it works perfectly. You can change bindings, dead zones, sensitivity curves, and even rgb.

Hello! I have an Aolion K20 TMR joystick. I used to have an issue where, after turning on my computer for the first time, the joystick would go to sleep and fail to reconnect. This app helped me update the firmware from version 4.08 to 4.15. The joystick was recognized immediately in the app without any problems. Now, after the update, everything works perfectly. Everything’s great — thank you so much!

It is a useless app, I bought evofox duck 2, but it is not showing any game, evofox has fooled the public.

★☆☆☆☆ Howard Blatz · Apr 30, 2026

Refuses to connect to Bluetooth, no viable PC/wired option available. They work technically, but they refuse to shut off while connected to the Switch 2 and continuously drain the battery. Can't update the firmware because the app constantly fails to connect to the controllers.

Can connect controller on key linker but cannot connect to device Bluetooth USELESS APP

★☆☆☆☆ Cristina Luz Gonzalez · Apr 6, 2025

Stuck on main screen where it shows device paired/available. I just downloaded the app, and it says it is up-to-date. I poke the controller connected and all it does is have a loading symbol which eventually goes away but nothing else happens.
