==Notes on using your Gemini with Android 8.1 ==
===Re-starting and booting Android 8.1 for the first time===
<div style='color: #000000; text-align: start; text-decoration: none;'>The first boot of the ungraded Android 8 Gemini will take a while as the system is booting for the first time.</div>
<div style='color: #000000; text-align: start; text-decoration: none;'>Once the Gemini has restarted, it will still take some time until the installation is fully complete. You will get an on-screen message that the Android update is complete. After that the device may still feel a bit sluggish as file formats and data is being adapted for each application to Android 8 formats. This process should last a maximum of few hours, but it is dependent on the storage of your device. The more data you have the longer the process may take. You may feel the device even getting warm from the processing of this data. </div>
===Android 8 security ===
<div style='color: #000000; text-align: start; text-decoration: none;'>Because the security frameworks are different in Android 8 and Android 7, you may be asked to re-authenticate your Google or other accounts as well as to re-grant permissions for the apps that you are running.</div>
<div style='color: #000000; text-align: start; text-decoration: none;'>Typically you will be asked to grant specific permissions with an on-screen message.</div>
<div style='color: #000000; text-align: start; text-decoration: none;'>If you notice any apps crashing, this may be because they are simply not compatible with Android 8. Please check in Settings->Apps if all the required permissions have been granted to the app that is crashing, just in case it is a security issue.</div>
===New features in Android 8===
<div style='color: #000000; text-align: start; text-decoration: none;'>'''[[File:Screenshot_20190508-135353.png|800x400px|center|border]]'''</div>
<div style='color: #000000; text-align: start; text-decoration: none;'>We have introduced some new settings for the Gemini in Android 8.</div>

<div style='color: #000000; text-align: start; text-decoration: none;'>You can also completely remove the Android Navigation bar from the screen by using the "Hide Navigation Bar" setting.</div>
<div style='color: #000000; text-align: start; text-decoration: none;'>You will need to restart the Gemini for this feature to take effect. </div>
<div style='color: #000000; text-align: start; text-decoration: none;'>When the Navigation Bar is hidden you will need to use the keyboard shortcuts for the Go Back, Go to Desktop and Apps list functions.</div>
<div style='color: #000000; text-align: start; text-decoration: none;'>The keyboard shortcuts for Go Back, Go to Desktop and Apps list are as follows:</div>
* Back - Esc (escape key)
* Desktop - Fn + d
