so I got a OnePlus One too

I'm amazed at how bad this thing is.  Is anyone else having the issues mentioned below?  Maybe I have a dud.

Firstly it is fully patched with latest over the air updates.

Touch screen seems unresponsive at times:

Reasonably often when I go to put my pin on the lock screen, nothing will happen.  Turn off screen and turn it back on then it will work.
Other times I will pull it out of my pocket and the touch screen will go nuts, hitting the number 3 or 9 over and over and over again, I can see there and watch it continually registering button presses.

Also at least once a day, standard apps on it like dialer or mail or settings will fault/crash and restart and send a crash report off to Google

Is the hardware buggy?  Is CyanogenMod buggy?  does it know how I work for?  What is going on!

Thanks
