# How big of a deal is Android wallpaper fingerprinting? **URL:** https://discuss.privacyguides.net/t/how-big-of-a-deal-is-android-wallpaper-fingerprinting/15557 **Category:** Questions **Created:** 2023-12-12T16:35:25Z **Posts:** 5 ## Post 1 by @anon29374801 — 2023-12-12T16:35:25Z I remember watching a video about it from Side of Burritos on Youtube. > **[How your phones' wallpaper can be used to track you](https://sideofburritos.com/blog/wallpaper-privacy/)** > > Is that family photo a simple personalization to your wallpaper, or is that being used to track you? I am to new to these types of things to really gauge how big of a deal this is. Is it recommended to either have a black background or something very popular or is this really only a concern for people with extremely high threat models? --- ## Post 3 by @jonah — 2023-12-12T18:58:02Z There are so many _other_ ways for native Android app developers to fingerprint devices that this is virtually irrelevant. The Android app sandbox is simply not designed to prevent fingerprinting in the first place. As far as I’m aware, the APIs in Material You to grab this color information aren’t made available to _websites_, which is where the real fingerprinting problems would begin, so I’m doubtful this would actually impact anyone. --- ## Post 5 by @anon63378630 — 2023-12-14T19:11:47Z Firefox also uses them for page widgets too, but the browser will always protect them from the website. > > > Tested working on Android/Mull 103 and Fedora/GNOME/Firefox 102 > > Reported here…: https://forum.f-droid.org/t/websites-can-know-android-accent-color/19133
