Microsoft is still trying to fix what appears to be a persistent touchscreen sensitivity issue for some owners of the recently launched Lumia 535. Microsoft has already released a software update designed to fix the problem in select markets.
Windows Central has received a message that was originally posted in the Microsoft Yammer Group for MVPs by Delfin Vassallo, the Social Media Operations Manager for Microsoft Mobile, where he talks about what the company is doing to fix this bug:
"We are sorry that some of you have been inconvenienced by this situation. We've identified some models of Lumia 535 are presenting different anomalies on the touchscreen performance. It manifests itself in several 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.
"An OTA (over the air) software update has been deployed in 23rd of December 2014, solving most of the problems but certainly not for all customers."
"Our Technical Support Operations team here in Finland, as well as the engineering teams in the US and China have the matter under investigation marked as urgent priority, in the meantime please use the troubleshooting offered by my colleagues in this thread."
"When our colleagues in the engineering team have identified the cause of the conflict, we will provide further information, whether this is another software update or an action performed on hardware at an authorised Care Point, (at this time Care Points have not received updated info regarding this topic, thus is useless to visit them)"
"We assure you that Microsoft does take matters like this very seriously and our teams are working frantically to resolve this concern for our customers. For the time being, we can only recommend that you use the troubleshooting provided whilst we work to ensure that the situation is properly solved, and that you accept our apologies for the inconvenience caused."
The company has also posted an FAQ on this issue on the Microsoft Mobile website that offers some suggestions for Lumia 535 owners who are having these touchscreen problems:
Check that there's no water drops or moisture on the touch panel. Wipe out the water drops and moisture to get the touch panel to function normally.
When typing on the keyboard, take care that you tap the center of the key. Otherwise a wrong key may get pressed if typing too fast.
When charging, use the original charger coming with the phone. The touch screen may perform poorly if charging with an 3rd party charger that is not compatible with the phone.
Check also that all the phone updates have been installed (Settings > Phone update > Check for updates).
We will continue to monitor this particular bug in the Lumia 535 and provide updates when we learn about them.
