Are you guys finding that after about a year of ownership that the micro usb connection to your Lumia 900 is flaky? I don't think my original charger works anymore with my Lumia 900. I use a charger for an HP Touchpad but the HP cable is flaky. I use my Nokia cable with my HP Touchpad charger. Is this problem widespread? I want to get rid of this phone before it really goes downhill.
