<h1>How to install GrapheneOS on a Pixel Phone </h1>
<img src="1.png" class="imgRz">
<p>In this tutorial we're going to setup graphene OS, an open source android operating system for google pixel phones. (Yes google phones, if you don't like it then you'll have to wait for functionnal <a href="../openhardware/index.html">open hardware</a> alternatives to arrive on the market.) Currently GrapheneOS is one of the most privacy-focused mobile operating systems given that it's fully <a href="https://grapheneos.org/source">open source</a>. and that they refuse to implement google services by default, unlike their competitors like LineageOS.</p>
<p><u>DISCLAIMER:</u> yes the quality of the photos taken are garbage :)</p>

<h2><b>Requirements </b></h2>
<p>First step is go acquire a Google pixel phone, and a model <a href="https://grapheneos.org/faq#supported-devices">that supports grapheneOS</a>. In my case, i purchased a Pixel 6 model. Then on the host OS on your computer, install the required packages:</p>
<pre><code class="nim">
[ nowhere ] [ /dev/pts/11 ] [~]
→ sudo pacman -Syy android-tools

<p>Here on the phone, we need to enable developer settings, to be able to enable the "OEM Unlocking" option:</p>

<h2><b>Setting up multiple Profiles (for Public, and for Private use)</b></h2> </br> </br>
<p>As we have seen <a href="../internetsegmentation/index.html">previously</a>, it's always a good opsec practice to separate public use from private use. This can also apply on your phone, In this case we'll create a profile specifically for public usage, while we keep the main one for private usage.</p>
<img src="22.png" class="imgRz">
<img src="23.png" class="imgRz">

<p>Now in there, we can keep the closed-source applications in the public usage profile, while we keep the FOSS applications in the default private usage profile. </p>
