I can' t hang up

Rumor has it you can access it from MediaTek Engineer Mode (aka MTK Engineer Mode).

One easy way to get there is to install an app called "Mobile Uncle Tools". From there, you should be able to launch into MTK Mode. There's also some key stroke sequence you can use instead, but I don't know it off the top of my head.

Once you're in Engineer Mode, go to the "Hardware Testing" area, then scroll down to "Sensor". There should be an option for Proximity Sensor in there.

A "hack" alternative you guys can use in the meantime is to use the power button to end your call. It's a setting you'll have to tick in Android, and you really SHOULD calibrate your proximity sensor to work properly, but it's an easy workaround.

Go to Settings.
Go to Accessibility.
Tick the box that says "Power button ends call".

I've got this app, got to sensor calibration and gives me "calibration failed "

And the problem is not only because I can' t hang up (I already can do it, using the power buton) but because the device dyes for 10-15 min. and I can' t use it , can't dial, can't see even the time - nothing
