I have had my Eris since Nov. and have just started getting the silent call and scrolling to the left when connected to a charger. I called yesterday to get a replacement and ask if these were common problems. (knowing they were). She told me not only had she never received either of these complaints....she checked the computer and neither had EVER been reported by anyone about the Eris. Geez...imagine that! I hope my replacement will work like this one did the first 8 months.
