Nokia C7, Nokia E7 - locking the screen during a phone call

First of all I want to mention that Nokia C7 and Nokia E7 are very cool phones, I like using them and the new Symbian^3 operating system is fast. 

Back to the issue: locking the screen during a phone call

Nokia C7, Nokia E7 and probability all Symbian^3 phones made by Nokia are designed to turn off the screen during a phone call (without usage of headsets). This is a required feature for touch screen phones that prevents the user to accidentally touch the screen during phone calls. 

Phones have some kind of a proximity sensor near the internal speaker that turn off the screen when you hold the phone close to your ear. The problem with Nokia C7 and E7 is that if you are a normal person you will move/tilt the phone a little bit while you are talking. 

The sensors are too sensitive or too few and even a small movement will light up the display and the touch screen will interact with your face. It happened to me lots of times and after putting people on hold/muting them and even terminating the conversation I found out a fix for this. 

Maybe it's obvious to others but here's how to lock the screen of Nokia C7 and E7 during a phone call:

After dialing the number you need to slide the lock button (on the side of the phone). This will lock the display! You will not accidentally touch the screen with your face and you'll have pleasant conversations without interruption. 


  1. Thanks for this suggestion . very useful one indeed

  2. Pity Nokia don't help their users. There is no need for the phone functionality to appear on the touch screen in the first place as there are buttons provided to accept and terminate calls. These buttons duplicate the touch screen icons and frankly I prefer the buttons. Is there an App that could take the phone functionality off the touch screen entirely?

  3. Stephen the on screen controls can be helpful, for instance you can enable/disable the LoudSpeaker. Nokia should handle the sensor like other touchscreen phone vendors do - like Samsung and Apple.

  4. Thanks for letting me know about these useful information,,,vodafone deals
