A Mod @Nokia Discussion Forums also made note of this issue, stated to go into the Diagnostic app---> Nokia Diagnostics-Access Code: ##634#
Scroll down to the Proximity Test....as it should show a 'Yellow colored Circled'...then when you place your hand over the front camera sensor...it should then change to a 'Green colored circle'....
If the device does not perform like this, then the sensor is defective and the device should be returned for exchange...
My 3rd White L-900 past this test...however it is strange that the sensor (placed where it is)...would cause this issue....disappearing call menu...etc...
Thanks for this info....if I can find this thread @Nokia Discussion Forums will paste a link here...
Although this thread relates to Lumia 710 and Proximity issues (its more-then-likely) the same for Lumia 900:
Re: Lumia 710 Proximity sensor bug
[ New ] .
Thanks for your post!
Your can check if he sensor works correctly by going to diagnostic tools (if not available dial ##634#) and select the proximity test. You will see a yellow circle. When you put your hand over the sensor, which is in the left top corner of the Lumia 710, the circle will turn green until you remove your hand. If this does not happen as described goto a Nokia Care point to have your device checked.
Hope this helps,

hi my phone also having the same flickering at random time.
to confirm with you, when you switch to brand new phone,before you install any apps/update does it flicker?
i recall all the phone in display booth are working fine. I played with some of them for a sometime - about 15 minutes each. all are working fine.
so this is my speculation, but i suppose the problem is not hardware, but there are apps that is incompatible.
i tried to install several apps. i notice that after i uninstall microsoft lync/lynx 2010. it get less flickering.
perhaps someone can try to reset the phone and track which apps after being installed that cause the flickering.
