qr code is the squares code that, if used with a qr code scanner redirects me automatically to a website or to download a pkpass file, right? after downloading said pkpass file to my android, any wallet application like fosswallet should recognize it and add it to the local library (on my android device), right? what other formats do transportation authorities use? To those residing in Germany, is pkpass use widespread there? What are common formats used there?

I want to start learning android dev and I understand that I’ll need the android sdk and cli tools. I want to try it in a kvm because even though it is open source, I would like to keep it separate from my main system. Which distro and vm settings do you suggest I use? Any other tips or your experience with android development on linux would be helpful as well.

I have an older Samsung Galaxy A3 with an already unlocked bootloader (it comes pre-unlocked) that I want to clean & root. I have a few apps like firefox, some games, DraStic, notesnook, etc. as well as my music. I want to keep all of this of course bug remove all the other bloat i dont need. I dont want a custom ROM or anything. The samsung ROM is good enough (android 6.0.1) I am very unaure on the process though & I dont want my old phone to get bricked so I'd appreciage it if somebody helped me out here, thanks.

It came as an update, and I installed it without thinking. I did see the size before launching thankfully and uninstalled - how screwed am I?

(Maybe edit the community name in the mod settings)

Is there an Android ROM that has the ability to provide the app with fake camera stream, location, microphone stream, gallery, storage files etc...? It would be incredibly useful to allow apps to work while giving no info / no access to private informations / permissions.

I'm going on a trip soon and trying to get myself some things to do. What Android games should I play? Obviously not some cash grab games but something proper. My most played games are Kerbal Space Program, Minecraft, Stormworks, Red dead Redemption 2, Forza Horizon 5, Farming Simulator 19 and 22 and BeamNG. I'm thinking of Pokemon Fire Red on some emulator. Other suggestions?

I experience that my memory is used up on my android phone, but I dont understand what drains the memory. I only found AnotherMonitor on fdroid, but it doesnt appear to show which app is consuming memory. Only total consumption. Are there any good apps or solutions for this? Or at least as autonomous slash private as possible.

I know it's very specific, lol. But my Samsung S8 is basically just a portabel 4G modem for me now. Since the screen is cracked and I don't want to spend money on that old phone. I usually access the phone to scrcpy, it works but since the screen is unuseable, I can no longer give adb access to another devices. So I just want to know whether is it posible to give it some short of webui that I can access to do basic stuff like turning hotspot on or off, etc.

Hello, I just switched to Android 13, and I am wondering what is this toggle doing on top of the 3 options? A bit confused. Edit: on Asus zenfone 10, in case it varies from vendor to vendor

any ideas on making an android phone (LOS 22.2, root) more dormant in standby? I got a couple older ex-flagships with beefier SoC that aren't super-energy efficient and chew through the battery without doing anything. they got no SIM cards and broadband is disabled by way of Airplane mode, they're on wifi with very few background apps (syncthing, KDE Connect - tried without them, same) and still they barely last 24 hours doing nothing, just sitting there with SoT of like 5 mins. tried just LOS (with unifiedpush) and LOS + microG + replace FOSS apps with Gplay apps, thinking that background sync could be the issue, no significant difference. I've tried some tools like 3c CPU Manager that let you underclock CPU and GPU, but them things are for people trying to maximize their SoT, like use less power while they're being used. what I'm looking for is something to bring the consumption way, *way* down when it's not being used.

Replacing Nokia 8.3 5G cuz it's broken

Along with the changes mentioned above, VLC for Android v3.4 includes the following improvements: Search a media Play streams or playlists More media info is displayed Improved pagination Improved cover synchronization Performance improvements-

*(cross-posted from: https://lemmy.ml/post/19917523)* Basically, what the title says. Do you use any app, that is proprietary, but either has no OSS alternatives or they're all not good enough? If there is an alternative, what keeps you from switching?

If I connect my laptop to a Wi-Fi hotspot provided by the phone? Is there a way to let me SSH into the laptop via an IP address? Or vice versa, allow the laptop to SSH into the phone (I can already SSH into my phone on my local network by using an app that provides an SSH server on my phone) from the laptop while it's connected to the hotspot.

Hey y'all. Like the title says, I'm looking for an android sms app. I used to use signal, but they removed support for it in October last year. I switched over to qksms which has been great, except it doesn't support video, only pictures for MMS. The default app that came with my phone doesnt support group chat titles, and sms messenger from f-droid says it supports video mms, but it keeps failing to send video (despite the size being 1.4Mb). Y'all got any other suggestions?

I ask because I have an old phone running Android 7, and aim not really in a place to upgrade. There's exactly 1 build of Android 8 for this phone on XDA but it's an unofficial version of Lineage that breaks VoLTE, so I don't use it. All in all, I'm pretty happy with the stock firmware anyhow, I'm just wondering if there's any way to take Android 8's autofill framework and add it to Android 7 as a user app. Something like an accessibility service or an Xposed module. I have pretty much no knowledge of how to code, so I'm asking here. Any help is appreciated. Thanks!

I'm looking for a way to dump raw data from an entire phone or at least the `sda` block to a PC, using a method other than `adb pull`. When I run `adb pull /dev/block/sda sdaDump.img`, it creates a dump file. To find what I need, I have to search through this raw data using a `Hex Editor`. If the dump comes from a fully functioning phone, I can usually find what I’m looking for because all the data is still intact. However, I accidentally wiped the `metadata` partition on my phone, so the decryption keys/files are gone. Now, because of that, some folders appear empty when checked with TWRP's File Manager, even though the actual files are still there. If I create a dump now, the raw data in the file won't be the same as when the `metadata` was present, and those folders weren't showing as empty. Running `adb pull /dev/block/sda sdaDump.img` now results in a dump where the `Hex Editor` shows zeroes (no data) where these files should be. Is there any alternative method to create a raw data dump of the `sda` block or entire phone storage, that will capture that data as it is (not empty folders, but the data in them), even if it's encrypted? I don't want to create the raw data dump onto the phone storage and then transfer it to a PC, but something that works like `adb pull`, in the sense that it pulls the data from the phone directly onto a PC. Thanks a lot in advance to everyone!

Hi, I recently experiment by installing vscode and nix on an Android tablet. What do you think about it ? Have you used an android tablet to create a simple development environment?

The problem with most smartphone image editors is that they are meant for quick edits to photos. Usually they are limited to cropping, adding filters and drawing. I'm looking for something a little more capable, something more akin to a traditional desktop editor like GIMP. Open source is a plus.

I'm trying to make sure that if I import a phone to my country, it will likely work pretty much wherever I may go here. Most phones I'm looking at support every 4G band operated here, but I've noticed that on the GSM arena website, they will often give a list of supported bands for a given phone followed by a dash and a region name like 'Asia' or 'international' or 'USA'. One of the supported bands I'm looking at is operated in my country, but seems to be pretty rare, if I use that as a criterion the list of devices shrinks considerably as does the number of brands to choose from. One particular phone I looked at only lists support for the specific band I'm looking at in it's "-USA" list of supported bands. I'm confused by what this means for me, if that band is used in my country and I import a phone that only lists the band as supported in the US does that mean the phone wouldn't work here if I'm in an area where the only available tower operated on such a frequency? Why not? It sounds like it's physically capable. The other question is, how do you assess the likelihood of this being a problem? The relative rarity of support for this band and the fact that it's only *officially* supported here, but seems only to have recently been licensed for people to build infrastructure operating on that band makes me think that there are likely very few towers actually using it here, but presumably more will eventually start to do so. My current phone has lasted me 6 years, almost 7 so I'll want to future-proof in this regard. In the time since I bought my last phone, carriers have abandoned any non VoLTE support so if the phone I bough then, hadn't had this compatibility it would have become a brick well ahead of its time so I'm weary of something like that happening. EDIT: Something has occurred to me that didn't before and might answer my question, but then I guess it'd be good if anyone knew because this is only a guess on my part. Maybe the dash followed by region name is referring to model variants, as in, if you buy the US variant of the phone, then it supports these bands, and if you buy the international variant, it supports these bands etc etc. In that case, it would presumably mean that if I bought a variant model of a phone that lists support for a particular frequency band it should work anywhere in the world where those frequency bands are used not just the region mentioned after the list. I guess the trouble is that usually the sites I can find selling these phones to consumers in my market don't go in to anywhere near that level of detail so I'd have no way of knowing which model variant it was other than simply the manufacturer's marketing terms for their product lineup.

Asymmetric bezels low key bug me. Are there technical reasons why they're hard?

So, like it says on the tin: I want to try GrapheneOS on my next new-to-me phone, which practically limits me to the Pixel series. And my price point will likely limit me further. Anybody got thoughts on the Pixel 6a vs Pixel 7, those exact models (e.g. not Pixel 7 Pro etc)? I currently have an old phone with Snapdragon 845 and 6GB of RAM which still performs well enough under LineageOS with microG to keep me happy. Fears: that I'll miss the microSD slot; that the 6a's battery life might suck even on GrapheneOS; that the battery on a Pixel might be hard to replace. Nice-to-haves: a camera that works well in low light. Thoughts?

For a while now I have had this problem that everytime I used a voice command for Google Assistant that a few minutes after the command got executed I get the sound of Google Assistant activating and waiting for input for like 2 seconds or so (also with the green microphone activated icon in the corner). Does anyone else experience the same problem or has an idea how I can get rid of this?

(Sure would be nice if I could post this on GrapheneOS's unofficial sublem, but anyway . . . ) Using Graphene, I made a local Seedvault backup on my phone that I would like to upload to the cloud, specifically with/to Filen, but I can't seem to do this, and I'm not aware of any of my other files having this issue. Is this a permissions issue with Seedvault, or is there something else going on?

Is there any solution to configure termux to use system default theme instead of what i setup using termux styling app? Even a basic option to set different themes for different modes will help l, so that i can configure it to switch to zenburn when system is in Dark mode and Google light when in light mode.

A new version of liftoff just dropped and it has **my** most needed feature. The ability to adjust the size of comment text.

Reason for posting this question - my laptop battery died and it turns out the bios gets reset every time I turn it on now. Made me think of the old phones I have which cannot be repurposed without getting new batteries.. I guess mandating replaceable batteries is enough but IMHO it should go further
