I have had my Droid 2 Global for about a year and a half. The issues I am having have been recurring for several months now, and about two weeks ago, I was sent a warranty replacement, so the phone in my possession is supposedly as-good-as-new. I do use the Backup Assistant to back up my contacts and settings, but install applications fresh. Now, in spite of the new phone, the issues I am having are beginning to recur. I worry that it is perhaps a software issue/somehow tied to my Backup Assistant settings, but do not know what to do. The issues I am having are as follows: *The sound intermittently does not work. This happens at random, and covers notification and ringtone sounds, as well as in-call volume and media sounds. I have my alarm settings set up to play the alarm even in silent mode, but this morning even though the phone was not in silent, the alarm did not play a sound nor did the phone vibrate as it usually does. *The camera intermittently does not work. Sometimes the camera app simply crashes, but even if I can load it and snap a photo, I cannot access the photos through the gallery/camera apps. If I retrieve the files directly from the simcard they seem to be intact. *I get random ads in my notification bar. I am not sure if this is related, but I started noticing them around the same time as all of these other issues began a few months ago. The only thing I can think of is that I have some kind of weird virus or something, but I am not familiar with maintaining the android OS to fix this sort of thing. The only thing I can think of to do is to hard reset the phone and forgo the Backup Assistant/replug my contacts, settings, etc all by hand. Any other thoughts?
