How to force the update to show?  Checking in About phone/Wireless Update it says that my device is up to date ..

How to change / increase vibration in engineering menu ?
There are only testing functions, I didn't find any way to set/change functions ?!

Where should i download it from?  I had checked with my phone wireless OTA and it says there are no new updates???

Yes..  
I would like that very much. This way you can prolong the battery life of the phone even more and also I will not be bothered with phone calls/ messages after 10 p.m. when I sleep

No OTA for me

This happened to me also..
Please make the button inactive till the time I open manually the intercom application(after the app is opened the button can be active)

yes...  I actually accidently pushed the button, when taking the phone in my hand and the application opened..Not goood
