NVIDIA promised a 5.1 update for the Shield tablet would hit devices this month, and it looks like the company is making good. We've got numerous tips that say the update is available right now on the WiFi tablet. Head to the settings and grab it at your earliest convenience.
NVIDIA lists the changes in the 200MB update as follows.
Upgrade Android Operating System to version 5.1
Improved performance and responsiveness.
Enhanced security, including support for Android for Work.
Improved quick-settings menu, profile management etc.
Improved display performance
Enabled Global Tone Mapping feature. This feature can be toggled by the user.
New firmware update for SHIELD controller
Improved pairing experience and other optimizations.
Please note: You can update the SHIELD controller over WiFi. Look out for a notification on your SHIELD tablet.
System wide improvements including camera, audio, modem (LTE only) and other fixes
You probably know by now what Android 5.1 is all about. It makes a few UI tweaks, improves how notifications are handled, and patches some bugs. The new global tone mapping is unique to the Shield Tablet. It will be interesting to see if that does anything for the device's generally average screen.
The LTE version of the tablet sometimes lags a few days behind the WiFi variant with updates, so expect that to hit anytime between now and the middle of next week.
