After experiencing random reboots,lockups, etc an average of two a day I decided to see if I could find an app to help. After doing some searching in other forums, I thought these might be caused by the phone running low on memory. I understand that Android manages memory without outside help.
I downloaded a free app called "Auto Memory Manager" from the market-very easy to set up. I have the threshold setting on mine set to "mild". I installed it this past monday morning and have not had a single reboot or lockup, not even while using the music player.The phone is smoother and more responsive as well.
I wonder if anyone else has tried this program and if it has worked for them also? Will report if problems start again.
I still have the start up after shutdown issue however, but overall the phone works well now.
