About Android Headset Tester
This app will help you test your headset/headphones.
1) With this app you can easily determine if headset (TRRS 4 pin) or headphones are connected to audio jack. Some Android devices do not show you this information (for example, Samsung S4).
2) App can be used to make electrical tests. If you want to assemble your own remote control, you can test how device will recognise different values of resistance.
Tips:
1) While plugging, no one button should be pressed on remote controller, otherwise device will not recognise mic.
2) I have never seen 4-function wired headset, but in google specifcation there is reserved "voice" function. I tested it with command "adb shell input keyevent KEYCODE_VOICE_ASSIST".
It was introdused only since Android 5.0 as keycode 231. On 4.4.2 this keycode was used by samsung as KEYCODE_EMAIL.
3) This app only will show you generic headset buttons. If you somehow modified kl files in /system/usr/keylayout, then you should better use KeyTest app. This app will help you test your headset / headphones.

Instant crash. Doesn't even open; sent technical feedback so hopefully developer can correct compatibility problems with Nougat v. 7.1.2 *Edit:* got an email from the developer saying they resolved the compatibility issues Nougat. Tested the app, works brilliantly. 1 star, changed to 5. This is a good developer, that is truly invested in improving their app. The functionality of the app is also worth noting. There is also an included 'handbook' for people that are unsure of what TRS, TRRS means; and the difference with Apple TRRS vs the rest of the world.
