Lately (as in the past week or so), my phone hasn't been working very well when I tap on apps or on the camera. I thought it was because my screen was dirty, but this isn't the case. I've cleaned it several times and while it works just after it's cleaned, it becomes non-reactive shortly after. It's getting a little annoying and I don't really want to get a new phone now as my contract expires this fall (when the 7/7Plus comes out). Has this happened to anyone else? My husband, who has the same phone, does NOT have this problem.
