Need your help desperately and am quite embarrassed regarding my stupidity and ignorance .
Last night I noticed that the App. for Fox News works kind of really slow. I decided to change the DX from 3G to Wi- Fi since I had read and also heard that WI Fi is a lot faster than 3G. Bad idea, I know this now. The Droid emblem came on, and for a few seconds I could not wake it up. After pressing the Home button, finally it came back on again, but it looked a little different. Had 7 Home screens again (instead of only 3); several Apps were missing which includes My BackUp Pro. Could not find any of my missing Apps in the Apps tray (swiped my fingers). Most interesting of all, I now have in the lower left hand corner a notice stating "Safe Mode". I have no idea what this means, and how to correct this.
Still love my phone very much and I am fascinated by it. Did it give me an accidental unwanted Factory Reset or something similar not quite as harsh?
Thank you in advance for all your help.
