I have had my One for a little over a month now. Phone started out as lightning fast. However of the last few weeks it's become slow and gummy. Seeing the please wait with the circle thing a lot. It will often do it's own thing.. I haven't installed any apps other than angry birds and words with friends. I've tried shutting phone down to no avail. Anyone have any ideas what may be causing this? With the exception of this phone not working well with Bluetooth headsets, it was a good phone. I would appreciate any tips. Thank you.
