Android phone saving metadata for screenshots

I always remove this data from my screenshots before sharing, but is there any way to prevent this from happening in the first place? I've searched and searched, but all I can find is information about how to remove the data after the fact, which I already know how to do, but it would sure be nice if it never got added in the first place. Thanks.

Is this all the metadata it adds?

Because the information you've shown here is not at all sensitive. It's just the timestamp, Android version and time zone.

- No, but when combined with other data it makes identifying someone more accurate. And what is the need for it anyway? OP is reasonable to not want it IMO.

- I knew I'd get a comment like this eventually. There's no rational reason it should be adding this data at all, and there should be a way to disable this behavior. The camera I use doesn't add this data when I take a photo, and there's no reason taking a screenshot should do so.
  
  The software version doesn't just say "Android 14" either. It looks very specific.
  
  No matter how you look at it, this is not an acceptable way for a device to behave, with no way to change it in settings.

  I don't share screenshot frequently, and I store them for a long time, in 10 years in the future this data can be useful, I won't remember what phone and rom I had, so it can be useful for some people. I also store gps data in my photos' exifs, but again I never share them on the public internet.
  
  But a button to switch it onoff would be useful, that's true.

  Yeah, it's likely a rather precise Android version.
  
  So what? What does the Android version you use reveal about you? What part of your threat model does it violate?
  
  Here, you can have the exact version of my phone: lineage_FP4-userdebug 13 TQ3A.230901.001 2023111915 test-keys. Can you identify me now?
  
  (In my case, you theoretically actually could because my version is unique because I homebrew my Android but if you didn't know that, it'd look like any other FP4 with !lineageos@lemmy.ml on it which is why I'm not at all worried.)

  Adding useful metadata that reveals no actual data about the user is a great feature and not worth adding a setting for; especially not in the UI.
  
  I didn't know about this before but I'll look out for that whenever sends a bug report of a mobile app with screenshot as it might include the device and Android version used which is super useful info to have when troubleshooting.

That's so weird, exif on a screenshot? Usually my quick fix to remove exif from something when I'm on the go is to take a screenshot of it. I'm on lineage 21 and according to exiftool there's no exif data on my screenshots.

- Do you have a Samsung phone? I'm starting to think it might be yet another Samsung thing.

  Google Pixel 5, if you're using a stock rom then that sounds likely.

- On lineageOS 20 it records the exact android build string as the Software for me, so "Android lineage_pdx215-userdebug 13 TQ3A.230901.001 b30079afa2". Which is probably enough to uniquely identify me, and you if you have a less common phone or are on an older or uncommon version.
  
  Needless to say I am pissed.

  I actually just realized lineage 21 does this too - I didn't notice because cropping a screenshot with Google photos seems to remove all the fields (I also have the build string and timezone offset). Which is weird because cropping an actual photo the same way - as you would expect - preserves all the notable fields like timestamps, phone model / lens info, and the same "Software" field which for my photos is just "HDR+ 1.0.commithashlookingstring"

Wtf. What phone are you using?

- Basically all new phones have that.

GrapheneOS Camera is very nice. May only work on Pixels, but on stock android (which is an insane tracking platform you should ditch) too.

Https://github.com/grapheneos/apps/releases/latest

Download their appstore, there you get the camera app.

- Thanks. I've been looking for a replacement app for the camera since the one I use was bought out.

  This was about screenshots, sorry. No idea, dont think you can change that without a different android OS

Same here, but no "sensitive" information like what Android version I use or anything like that. It depends on what phone you use, I guess. I use a Pixel 6a with GrapheneOS.

- Mine's a Samsung S21FE so I don't think I can use that OS

ObscuraCam of Guardian Project doesn't save metadata. OpenCamera is highly configurable.

edit: ah, screenshots. I think in LineageOS it's part of the launcher (app-switch doesn't work with default launcher disabled) or backed into the system. If it's the second and you have a vendor OS, guess you can only flash a custom ROM to fix it.

5
- Yeah, unfortunately I don't believe I can flash a custom rom onto a Samsung. Ugh.
  
  Thanks for responding!

  You can, but, it's a select few models and most are older.
  
  Edit: personally I don't flash my phone because I'm poor and can't risk bricking it

What phone, what camera app, what Android version (and be specific if the manufacturer or service provider added their own customizations, as is common with Samsung and most major service providers).

3
- Android 14, and it's Samsung so I know they add their own restrictions, etc., but I'm not sure what they all are. Nothing good lol
  
  I'm using Simple Camera, which I do plan to replace, but it doesn't save exif data to the photos I take. It happens when I use the volume + power button combo to take screenshots.
  
  When I open any photo taken with my camera, I see no exif data at all.

  Oh, yuck. Yeah, I have a Samsung phone, too, and can't figure out how to strip exif data from screenshots. You might be stuck with a third-party exif-stripper app.

What app are you using to see the exif data? Perhaps my screenshot has this info as well but the different apps I use to view exif data do not show it.

2
- I'm using an app called Image Toolbox
  
  I use a FOSS camera, and when I take photos I can see there's not any exif data, but there is when I use the volume/power combo to take screenshots.

  Screenshots are taken using a different app (screenshot utility). Camera apps have nothing to do with it. Who is your phone's manufacturer?
  
  6
  
  Ok, yes, my phone (which is not a Samsung) also includes some info in screenshots.

I don't know of a screen shot app that works without addind metadata to screen shots. What I use is "Metadata Remover" from Fdroid: https://apt.izzysoft.de/fdroid/index/apk/rocks.poopjournal.metadataremover

You take a screen shot, open the screen shot image from Metadata Remover, click on "Remove metadata", and the moment it's done, it'll take you to share automatically.

I hope this helps you.

This shows how to disable it on the default camera app: https://www.techbone.net/samsung/user-manual/geotagging

- This only works for photos taken with the camera, not for screenshots

  I can't find anything in the settings, sorry

Why do you care if people know what Android device you're using? To me this is a non-issue.

Social media and messaging apps strip meta data when you share media, so for the most part no one can see the information you care about. It's only when you start sharing content via services like OneDrive where people will be able to see the meta data.

- To me this is a non-issue.
  
  Clearly, I feel differently. This may blow your mind, but people have different feelings about sharing information that is so specific that it can be identifying information.
  
  Did you come here just to insult me, or do you have any actual insight into my inquiry? I really don't understand people like you. Just ignore the post if you don't care or don't want to be helpful.

  Clearly you didn't read my comment... Did you read the first thing I said and went full on blind rage or something? Read it again for the insight

I love when people post well known and obvious information. if you hadn't realized metadata is present then idk what to tell you.
