In the middle of the last year I have noticed that my Gamini PDA is not
detecting it main camera. It wasn't a big issue as I use the Gemini
rarely (it's Android 7 cannot be upgraded and many apps cannot be
installed on this device at all) and the camera was quite bad.
Yesterday I tried to check connection of the camera but nothing helped.
It was just and add-on (even if expensive one) so I had the "old" back
cover without the camera hole. Thus I have removed the camera and have
installed that old cover.
Problem solved...
I also have verified that my Pebble SmartWatch can be still synced with
the Gemini PDA. I need to use both more as this is great fun.
