So here is what is going on. I got the M during reboot after the 2.2 update. After a long battery pull it started working. But now every time the phone shuts down I get the M, just sitting there when I power back up. The phone actually will ring when I get a call or text. I even turned the phone off by pressing the power button and pressing on the screen where the Turn Phone Off would normally display - so that means the phone thinks the screen is up - but it isn't - all I have is the M.
I called Verizon and even went into the store to no avail. We tried factory reset, wiping the cache and anything else we could do. Their solution is to send me another phone, now. I even called Motorola and they had no solution. The problem is that I am worried that I may have the same issue with that one, which will be here Friday.
So, I want to find out how many other people have this problem. You may not even know about it because you never shut your phone down. So, try turning your phone off and then turning it back on and let me know if you get stuck with the M (If you dare risk it). If it gets stuck, you can pull the battery for a little while and put it back in and it should be good. I just want to know how widespread this problem is.
