Google Nexus S 4G maintenance release packs "enhancements to improve performance"
Although it’s not anything major, the latest maintenance release for the pure Google device for Sprint carries along only some “enhancements to improve performance.” However, it’s not explicitly stated as to what those enhancements exactly are – but either way, it’s probably an ideal decision to install it. From the sound of it all, the whole download and installation process should take roughly 5 minutes to fully complete, but it’s still a good idea to back things up prior to installation.
Again, if you haven’t you received the notification, you can manually initiate the over-the-air process by simply going into the Android settings menu. Some might question why we’re seeing an update so soon for the device, but it seems that it’s better to release it after launch as opposed to delaying the handset’s release altogether.
