I recommend you say NO to the latest revision of Android. I did not record the name as it passed my screen, I think it is “Lollipop 5.1”. I lost my voice mall application and the calendar app that I use the most. The 2 most common uses of my cell phone were taken away in one swoop. No warnings, no info, just deleted. I have a business prospect who is likely to call and get this message: "The person you are trying to call has a voicemail box that has not yet been set up". My new customer will think I am a dorkus or the victim of bad technology. Looks like the Android people have been studying software development with Microsoft employees. What is more, I have no idea how to find support for this software. Is someone going to read this post and give me a shout? Right now my phone is stuck in an infinite loop trying to set up visual voice mail. It has been about 15 hours now stuck on the same message: "Setting up Visual Voice Mail. Please Wait..."
