Proximity sensor troubleshooting

Display, Touch and Proximity sensing related troubleshoot

Proximity sensing

This phone does not have optical proximity sensor, like previous Nokia products. In this device touch module is used for proximity sensing purpose. Proximity sensing works when call is active. When conductive large object (e.g. face or ear) is in touch with display, display is turned off.

Troubleshooting on call related (proximity sensing) problems.

Solutions to the possible problems are as follows:

Problem: Display stays on during the call when phone is next to the ear.

Solution: Advice the customer to keep the phone closer to the ear during the call. Cheek or ear should be in touch with the display area of the phone, not the frame of the phone.

Problem: Display stays black when phone is removed from ear during the call or Customer complains that phone display blinks or stays black when headset, charger or both are connected.

Solutions:

1. Touch screen functions or proximity sensing may be affected by humidity, rain drops, make-up, or dirt on the display. If your phone touch screen becomes unresponsive, use a cleaning cloth to wipe the touch screen clean. To avoid scratches on display do not use anything that could scratch the display and do not use chemicals for cleaning.

2. Advice the customer that two short power key presses wake up the display if it stays black in situation where is should be active.

3. Check that latest Phone SW is in use. That has the best proximity sensing parameters.

4. Check that user has original Nokia headset and charger in use.

Problem:

Customer complains about accidental key presses during the call.

Solutions:

1.Touch screen functions or proximity sensing may be affected by humidity, rain drops, make-up, or dirt on the display. If your phone touch screen becomes unresponsive, use a cleaning cloth to wipe the touch screen clean. To avoid scratches on display do not use anything that could scratch the display and do not use chemicals for cleaning.

2. Check that latest Phone SW is in use. That has the best proximity sensing parameters.

Troubleshooting on general touch related problems.

Problem: Customer uses display protective foil.

Solution: Advice the customer that protective foils may affect the functionality of the touch screen.

Touch screen functions or proximity sensing may be affected by humidity, rain drops, make-up, or dirt on the display. If your phone touch screen becomes unresponsive, use a cleaning cloth to wipe the touch screen clean. To avoid scratches on display do not use anything that could scratch the display and do not use chemicals for cleaning.

NOTE! Customer problems above do not require change of the display module. Changing the display module does not correct the situation. Updating the SW is the right procedure as the latest SW has the best proximity sensing parameters.
