After one of the last Android updates the phone will stop allowing connection to the computer. The option for Charge only, mount as disk drive… do not show up as options when you plug in the phone to a Windows 7, Vista or XP system. This is a problem with Android OS and may show up on different manufactured systems ie HTC, Samsung, LG…
I’ve included a Windows 7 Driver for Android OS 2.3.4 or newer. (Verizon)
This driver comes from LG. If you are not on Verizon please click the link below and download the correct driver for your carrier.
http://www.lgforum.com/resources – Here you can get the Android driver for all US cell providers.
On a side note we’ve also had One way sync problems after the recent update on calendar events created on the phone. These events do not sync to the computer however, events created on the computer sync to the phone.
