Is it okay to modify Android's system files? (for device company)
<p>I work for a company which is making device using the Android platform.</p>

<p>A UI designer asked me if it is possible to modify not just apps UI but whole Android's basic UI for example, status bar color, setting menu's font and so on.</p>

<p>I found a way to do this (editing <code>services.jar</code>... right?) but I wonder if it is okay to do it (release a device with modified Android framework code... does Google allow this or not).</p>

<p>Does anybody know about this issue?</p>
