Right-click on the icon and select settings, under the options tab, check all the checkboxes (there are 4) and try. b. You must pair them(computer and mobile) before transferring files. 2.

Where is the back light settings in Nokia N70 and other higher end Nokia phones?

I did a lot of google search for the Nokia N70 backlight problem. Many people are facing this problem. Under setting>>Phone>>Display>> you don't have an option to switch it ON of Switch it OFF. Of course, it may not be absolutely required. Another problem with backlight is time out delay. I found a thread in Nokia Forum stating the time out is happening after +30 seconds. Meaning, if you set it for 10 seconds the timeout happens after 40 seconds (10+30) If anybody found a way to switch on/off backlight please inform in the comment section
