Seems apps have alot to do with the touch panel being disabled. I have gone 3 wks with no issues, then bam! Can Nokia not integrate the touch display software inside the O.S.? Really? This is what make me hate WP. One messed up app and the whole phone becomes a paperweight. I have galaxy note 3 on the way. I hat android, but I need a phone that actually allows me to answer it when it rings. Maybe the wp8.1 will address this app issue. Oh if you want to know it was instagram's beta update. I haven't added any new apps just to make it easier to find the culprit. For all I know it could be a combination of apps that cause it or just one messed up app. It could even be wp8 just not handling an error in the background caused by too many apps, not enough ram, missed character in a command string. Who knows.
