I have an HTC One V. It is two years old. Over the past while it has become extremely slow in carrying out some functions such as calling up the list for PEOPLE or phone contacts or opening certain apps. There are other strange little quirky things going on as well such as not displaying the weather unless I manually touch the refresh button or shutting down Hangouts when I try to switch from one person to another. Etc., etc., etc. With the extreme slowness, I get the feeling that there is something running in the background that never shuts down. I am tempted to do a factory reset. If I do will I lose apps, contacts, music, photos, link to Koodo?
