Hi,

You need to make your phone writeable first. Go to System 
settings->About->Developer mode, then enable developer mode. After that, 
connect your phone to your computer, then run "phablet-config 
writable-image". It'll config your phone to be in writeable state, after 
that it'll reboot your phone. Now, install evtest again, and it should 
works this time.

BTW, making device writeable may mess up with OTA update. I recommend 
you to reflash your device after finish testing to ensure smooth OTA 
upgrade.
