Status Bar

Description

The latest version of AirGuard is showing the primary Material 3 color in the status bar- which is often light and has low contrast with the white foreground.

Reproduction

• Have an Android 12L beta phone
• Open AirGuard
• See bug

Screenshot

Proposed Fix

Make the status bar the same color as the background of the main app UI.

SVG color issues

Description

The latest version of AirGuard shows SVGs that don't align with Material 3 dynamic color.

Reproduction

• Have AirGuard on Android 12
• Run manual scan
• See undesired behavior

Thanks for looking into this issue!

Timezone: CDT
I took the screen shot after a while. But it is observed that the actual discovery time should have been displayed as 4:26 pm as there's Daylight Saving Time

Great work, thanks!

Neither in the app itself nor on the website I found any instructions regarding the bluetooth settings for the device.
I see two possibilities:

1. bluetooth off: bluetooth can be set to off and AirGuard will (somehow) briefly enable it for the periodic scans.
2. bluetooth on: bluetooth has to be set to always on.

Which on is it?

So, I have this airtag on an item at home for which I frequently get false alarms for tracking, despite it not moving with me. It seems to me like it is using for location also points reported by android which have a very high uncertainty, mainly those only used via triangulation of cell towers. Since those have a very high uncertainty (often >500m), it does not really make sense to use this as a location, and instead rely more on a gps fix or thelike (<20m uncertainty? <50m? dunno). That way most if not all of my false positives could be avoided

Having both AirTag and Tile Tracker detection in one app would be useful, likely reuse significant portions of the code base, and provide energy efficiency vs having another app price anti-tracking for Tiles and do its own BLE scans.

Currently, it seems the app only scan every 15 minutes or so?

I know Android limits the minimum PeriodicWork interval to be 15 minutes. But is it possible to add a button to manually trigger a scan?

Can you add an option to change how frequently the app scans for devices in the background?

The current version from F-Droid is missing a copyright notice from OpenStreetMap. OsmDroid does not seem to display it by default, so a custom one needs to be added.
Here's one option which might work:

//Copyright overlay mCopyrightOverlay = new CopyrightOverlay(context); mMapView.getOverlays().add(this.mCopyrightOverlay);

When viewing Tracker-lists there is no way to get back to dashboard using the UI (hardware back-key works tho).

Steps to reproduce:

1. Open AirGuard (start-page / dashboard should show up)
2. Click on first box which whows current risk level
3. Click on "Trackers detected" or "Locations tracked" box in top (needs to have detected devices) or click on "Other devices found" box in scond row
4. Notice that there is no back-btn in UI
5. Notice that nav-menu on bottom highlights "Ignored" even tho we are comming from dashboard
6. Click on "Dashboard" in nav-menu on bottom and notice that it does nothing
7. Click on "Ignored" or "Settings" in nav-menu on bottom and then click "Dashboard" in nav-menu on bottom again and notice that "Tracker Detected"-list is still showing

You should be able to whitelist devices, so that the app will not warn you every time you enter it. For example, I own a tile, and I keep it in my wallet, and even though I've muted it, the app shows that I am unsafe.

It would be good to have an "About" section in the settings, with some general information such as:

• "About" (what ist this app, what does it do)
• Authors
• Version
• Link to homepage

Hello,
I have found if you are fast enough or you double or triple click a menu item, the entire app panics and crashes.

Attached is a screen recording from my Samsung Galaxy S20+ 5G running Android 12, OneUI 4.0.

Hope this helps :)

Hi I’ve version 1.0.4 installed and It found two air tags the other day but I never got a notification they were detected. Is there something I’m missing or do notifications trigger under certain situations?

I’m running it on a Pixel 2XL running CalyxOS (android 11).

Please let me know if any additional information would be helpful.

Hi there,

First of all, I think this is an absolutely incredible project in terms of personal safety. I do have one suggestion from a UX perspective:

I think that sorting should be added to the Dashboard / Devices page (e.g. sort by beacon count, first / last seen, serial number or assigned name).

This can make it easier to find particular FindMy devices.

Thank you

After turning off "use location" in the AirGuard settings and reopening the app or making a manual scan, the setting gets automatically turned back on.
Here's a screen recording: https://cloud.hakimy.tk/s/x7Aondq6qXSJyDw

I'm using Android AirGuard 1.0.4 installed by F-Droid.

Thank you for an interesting app, already more beacons than I expected.

When I choose a beacon, it shows a map, but instead of showing the location at the time the beacon was identified, it shows my current location.

Using version 1.3.4, it seems like ignored airtags are also used for risk evaluation. This makes that feature kinda useless, if you usually carry an airtag with you

I had an AirTag detected a few days ago which followed me in public transport (but it was just someone else).
I just wanted to check out which options are available for "Feedback" / "provide some insights" to see if I can tell the app that it was a false-positive. When I noticed there were only options for true findings I closed the menu but noticed that the button was gone.
Did I accidentally flag this AirTag as a real finding?

In case it's really that simple to make an UNRECOVERABLE report which even CONTRIBUTES TO A RESEARCH you should implement some sort of final "send report" button to let the user know they are making this decision now. At least that's what I did expect when opening this menu.

AirGuard version: 1.2 (f-droid)

Opening the "Ignored" Tab and tapping the "Ignored" Button again will result in the Title of that tab changing from "Devices" to "IgnoredDevicesFragment".

OS: Android 11
Device: OnePlus 8 Pro
App Version: 1.3.4
Device Language: English

Wrong behaviour
Title of "Ignored" tab changing to "IgnoredDevicesFragment" (see Screenshot)

Expected behaviour
Title not changing, displaying "Devices"

Steps to reproduce

1. Open AirGuard App
2. Open "Ignored" Tab
3. Tap on "Ignored" again
4. See title changing

How to reproduce:

I've read your research paper (via this blogpost), which mentions that Airtags emit a status byte, which "might indicate battery life".

I was wondering if you could tell me more about this byte. Does it indeed represent battery life? If so, wouldn't that make it possible to circumvent the peridic mac address randomisation? E.g.

• Mac with battery life 56 disappears
• A new mac with battery life 56 appears.
• Conclusion: likely to be the same device?

If it's battery life indicator, is it a 0-255 representation of a 100% range?

Or does this status byte also convey other status information?

This app was able to find and alert me of one of the DIY AirTags I made with OpenHaystack when a regular iPhone couldn't. Really cool stuff!

That being said, I had to add the device to my ignored devices list. The mac address really helped to confirm it was really my DIY AirTag, but I thought it might be super helpful to be able to rename the AirTags you add to your ignore list, or just rename them in general. For example I don't necessarily need to add my friend's real AirTags to the ignore list, but if I was able to rename them and I got an alert, it would help me figure out if I should be worried or not.

Keep up the great work!

I left home today at 10:15. I got notified of several trackers today, and when I look at the timestamps and the locations of the pings, there are pings at my home at 11:00, 11:05, 11:20 mixed in with pings at my actual location (not home) at 11:15, 11:32. I don't own any trackers, but I'm probably near some in town right now. I've been in the same spot for the last two hours.

Is this a bug with location services on Android? If my phone gave AirGuard locations in different places while I sat near the same air tag, I can easily imagine it generating false positives as if that tracker was following me. Is this a known issue on Pixel phones, or maybe just me? Is there any way for AirGuard to know when it's getting a "stale" location from the system, or is that not really a thing?

In settings, AirGuard has location permission "all the time" and "use precise location" is enabled. The global "Google Location Accuracy" (aka "Improve Location Accuracy") is also enabled, but I wonder if this can actually introduce errors? I just dug into the developer options to see if a mock location app is configured, and no, there isn't one.

If the location usage is enabled and you open the settings twice, the location usage will be disabled the second time you open the settings. (Android 12)

"..., sie verlassen das Gerät"

Hello. I believe that you should add a tutorial on how to remove the battery from a airtag. This would be beneficial to those who do not understand how to do so.

If you cannot do that, try linking to a article that will explain how to deactivate the airtag.

Thanks,
SteadyStatus21

1. During the introduction, choose "Only when using the app" (preselected) at the third screen
2. Finish the introduction
3. Go to "Settings", toggle the "Location" switch
4. Choose, again, "Only when using the app"
5. You're stuck at the location history screen, i.e. the "Done" button does nothing

I've restarted the app countless times trying to nail down the exact same steps one needs to take to reproduce this, and the procedure above I think is where this happens the most ... but also not every time. Once I was stuck right away by choosing "Ask everytime" at the same screen. Frequently, the introduction starts over at the first screen when choosing "Ask everytime" at the third one.

Either way, something's not quite right.

OS: LineageOS 18.1 for microG
Phone: OnePlus 3
App version: 1.1.1 (also happened with 1.1.0)

Just tried this app and it isn't detecting my AirTag. It is paired with my iPhone and should be taking part in the find my network. I did some digging and saw that you are only listing for devices with the byte prefix (0x12, 0x19) but my AirTag is sending (0x07, 0x19) in the manufacture data. Here are some information about the manufacture data I could find https://adamcatley.com/AirTag#advertising-data.

It looks like my AirTag isn't paired correctly (I did try to do that multiple times) or there are some other differences as it is sending the payload for unregistered devices.

Any idea what it could be?

It would be cool if we could see a list (sorted by date) of beacons with their stored information.

Hi,

I have a question regarding the low power scan option if you don't mind me asking.

Recently, the label text for the option was changed from If enabled bluetooth low power scan will be used to discover nearby AirTags!<b>WARNING</b>: This could cause that some devices won\'t be discovered! to If enabled, Bluetooth Low Energy scanning will be used to discover nearby AirTags!<b>WARNING</b>: Without this option, some devices might not be discovered!.

However, according to the code, Bluetooth Low Energy is used regardless of this option, and the low power scanning mode is used when this option is enabled.

So, it seems to me that the label should say If enabled, low power scanning mode will be used to discover nearby AirTags! <b>WARNING</b>: When this option is enabled, some devices might not be discovered!. Can someone please confirm if this is correct? Also, please let me know if you want me to open a PR to make the change.

Allowing users to manually toggle the light/dark theme in the app's settings would be a good enhancement.

IIRC, the app will automatically pick the light/dark UI theme based on the system theme. However, this does not account for the case in which some users may want to pick the opposite light/dark theme in the app, compared to the system theme, since the light/dark theme isn't user accessible in the settings right now.

The text defined in

I'm trying to inform users of my open source smart home project when an actually new Airtag appears, but it's quite hard to do, since stationary Airtags rotate the mac every 15 minutes.

What I'd be interested in (thinking of implementing it in my project) is a way to detect when Airtags change their mac addresses, so that I can ignore the Airtags that the user was already alerted to.

They seem to change their mac address at regular interval (15 minutes), so if the Airtag count isn't too high it should be possible to do this. And if there is a way to extract other more stable values (such as battery level) it would become even easier?

I'd be curious if you think this approach is useful and possible. Perhaps it could be a feature of Airguard too?

P.S. How does Apple do this? I suspect they can only inform you if a devices is travelling with you because they can check the location of the Airtag and the phone and see if they move together for a while? That would imply Apple's protection app would also have a harder time informing people about malicious trackers if they are stationary too? After all, it migh just be your upstairs neighbour's Airtag.

First of all, I just wanted to say thanks for developing this app and making it open source. It serves it's purpose well and looks great.

After using it for a while I've found a couple of issues with the dialog that appears when you deny or dismiss a permission prompt.

Issue 1 - Crash

Steps to Reproduce

1. Navigate to the location permissions onboarding slide
2. Tap outside the permissions prompt
3. Tap "OK" on the dialog
4. Notice the app crashes with the following stack trace:

Issue 2 - Duplicate dialogs

Steps to Reproduce

1. Fix issue 1 and follow the same steps
2. Notice that two dialogs appear

The AirTag that I bound before can play sound. After I rebind it, the sound will be invalid.

After upgrading to 1.1.0 the history of found devices is lost, but also it does not find devices 1.0.6 (still) does find.

FP3 with LineageOS 18.1.

What else is helpful for you?

Some devices move with me but are known. Examples may include a tag owned by myself or a known trusted associate. I would rather label those devices instead of just ignoring them, so I can remember why they are ignored.

Great software by the way, thanks for all your hard work.

The app is much better than what Apple provide for iOS.
Is it possible to create an iOS version or cross platform version of this app?

Hi there, This application is not available on google play and Releases has no content. Could you please provide the apk file to download and use?

Hallo,
was sind genau Find my Tracker außer Air Tags ?
Sind das Air Tags von Android Geräten zb Samsung etc . ?

What exactly are Find my Tracker other than Air Tags?
Are these Air Tags from Android devices, e.g. Samsung etc. ?

I would like to suggest creating some method for the user to remove a device from the Ignored Devices list.

This is because I've personally accidentally put a detected device onto the Ignored Devices list by accident. Luckily, I was only testing the app out when this happened, so I could reset the app's storage and lost no important app data. However, this would not be a good choice for app users with an extensive and/or long device detection histories.

Hi!

I recently got an AirTag warning on a 3 hour trip on a long distance train, I traveled almost 500km with.

For me that was great, as I had a real world example for the app working. Also, because I got no further warnings after the train ride, I am quite sure, that this was not a malicious tracking attack on me, but a fellow traveler sitting nearby probably had an active airtag for her or his own purposes.

As an alarm warning can be a little bit intimidating in the moment when I receive it, making the connection, that it was during a train journey together with strangers, took a few moments. Maybe a hint to this idea could be incorporated into the alarm message or the guidelines regarding "false alarms"?

Although we are after two years of pandemic only getting used to it, but I guess long distance travel on busses, trains and maybe planes would be a usual reason for triggering false alarms?

[Bug] The number of last scans does not match the overview

The background here is supposed to show the location the tracker traveled. Without this I can't tell whether or not its a false alarm. This is in my normal profile without trackercontrol. Anyone else experience this?

Hi,
I love this app, but it's icon is quite striking, and not in a good way. I understand the want to not be too much like Apple's icon, but I'd definitely appreciate a more visually standard one for my homescreen. Thank you for making this app!

Hello, the app finds devices with different mac addresses every 15 minutes on the map and in the manual scan, but in the same place. Possibly mac books. What devices could that be? If there are no trackers, can you exclude them from the search?

I very appreciate your app, thanks for the possibility to get notified about possible tracking devices.
What I don't understand is the 'last scan' section on the status screen, what does that mean? My 'last scan' is often some hours ago, in worst cases some days.
I did exclude the app from battery saving and use a phone without google services (microG installed, but only partly activated).

Hi,

Where can I get an Android 7.0 version, the releases all appear to be for 8.0?

TIA.

Despite having the app excempted from battery optimization, the background scan is not working. Every time when opening it the "Last scan" field is from I have last opened the app.

I use LineageOS 18.1 (Android 11) and would be happy to provide any debugging information (adb logcat, whatnot) as needed

Currently, the status bar shows no icons in light mode & the navigation bar is not colored which looks something like this:
