Until this week, I wanted to throw the sucker under a bus
I have never had such an ill mannered device. It had bad social skills, ringing some annoying sound at the arrival of emails and messages---and the sound went on the entire time something was downloading. It would shut down a meeting
No matter the changes I made in "settings" there was no stopping this.
The other disgusting habit---the damn thing came with pop-ups There were times that I could not answer a call because of these pop-ups which ran for 10 sec before you could close them---and they were everywhere.
Finally, this week I made progress. The sound problem was not controllable in global settings but when I went to the individual (ie Outlook) I did find settings that allowed me to mute them.
For the pop ups, I found they were not directly related to the phone but to the apps. Virtually all apps now have the a fine print statement that they "Contains Ads"--and they aren't kidding. I got an app called "GoClean" that while it will not kill the ads it does identify which apps you have loaded that are guilty. I deleted most of them and now can use the phone without invasion.
