Hardware properly

The sold here Hardware Button basically works flawlessly. Every keystroke, also in combination -Single, double, long press, etc. is detected. Also the trigger on the Androidlockscreen works. Unfortunately zar recognizes the phone entries but the included software is not entirely error-free, which makes it partly to misinterpretations of the commands comes (volume change). The software is currently in version 0.977, I hope, therefore, that there is still something we did.
Furthermore, other software can be used from the PlayStore.
Five stars I give for the good hardware, processing, and secure fit.
