Johann, since you work at a lab, you’re far better equipped to put this to the test! Please do share if you have any insights.

Very interesting. I had a problem with my nokia lumia 920, the touchscreen stopped responding after a month of used, I first thought it was software, sent it to repair anyway and they changed my screen. I went back to my office and started the phone, it worked for a few minuts then the same problem appeared. I put the screen cover back to bring it back to the store and then i notice that the screen works again! I work in a laboratory and I am often in contact with electrical devices and electricity in general so I thought about static electricity. I took of the cover, tried, and it didnt work. I touched something grounded, and the screen was working again. SO I am quiet confident that static electricity affects capacitive screen. I will carry more investigations on the subjects.

Interesting. Like I mentioned in a previous comment, I haven’t had this problem on my Samsung phones so far. If it does happen again, this is worth a shot. TFS.

My trusty Pre 3 just jumped to its death, forcing me to transition to Androidland. For the next two weeks, this means resuscitating my mother-in-law’s old Milestone, whose ghost touching problem had become so bad that the device was unusable. I resolved to fix it and hit the interwebs…I stopped short of dismantling it and replacing the screen. What worked (temporarily!) for me? Rubbing it along a wool sleeve. It makes no sense to me; do you have any ideas? More details here: http://forum.xda-developers.com/showthread.php?t=1041943&page=5

Mickey, it depends on the particular model of phone I guess. I’ve had two Samsung phones since (Galaxy SL and now Galaxy Nexus), and haven’t had the same problem. Maybe the Milestone was particularly vulnerable.

Hi, I just want to say thank you for this entry. I found it while searching for any info on how static electricity affects capacitive screens, I basically wanted to see if anyone had any kind of problems with such screens due to the static they carry on themselves. I haven’t purchased a capacitive screen cell phone yet, but I’m considering it, and I seem to carry a lot of static on myself, esp in winter I actually get a shock every time I open the car door or touch the tap in the bathroom, etc… I wonder if you have any new info on the problem, I mean, if the screens are now made to be safer from static electricity, or is it just up to the user to take precautions?
