It's been a tricky thing for Microsoft to track, as not everyone experiencing problems complained of the same symptoms. According to Delfin Vassallo, Social Media Operations Manager for Microsoft Mobile, the issue can present itself in one of several different ways.
- Functionality of the scroll up/down and swipe left/right functions.
- Scrolling up/down or swiping left/right can result in an app or link being activated unintentionally.
- Functionality of the zoom in/out feature can be compromised if the user's fingers are less than 20 mm apart.
- Text editing, particularly at speed, can result in characters being missed.
- 'Ghost touch' - use of the touchscreen in wet/moist conditions.
- If the user's fingers are wet or the atmosphere is damp (i.e. entering a warm room from cold outdoors) buttons on the touchscreen can be activated unintentionally
Microsoft actually released an over-the-air (OTA) update back in late December to address the issue, and while it solved many of the problems users were experiencing, several symptoms still remain.
If you're one of the users affected, you can try some of these troubleshooting tips while you wait for a software fix.
