LPA managing application

Hi,

I'm currently trying to develop an android application to manage eSIM profiles including functions to download, enable, disable, delete profile. However at the current stage, I'm unable to even hit the LPA code while attempting to download the profile from a hardcoded LPA string within the code.
My download profile code for reference:
---------------------------------------------------------------------------
euiccManager.downloadSubscription(
downloadableSubscription,
true,
callbackIntent
)

//where downloadableSubscription:

private lateinit var downloadableSubscription: DownloadableSubscription //from.....import android.telephony.euicc.DownloadableSubscription
downloadableSubscription = DownloadableSubscription.forActivationCode("String_value_of_the_activation_code")
---------------------------------------------------------------------------
I'm sure the function is being executed since I've defined 2 toast prints before and after the function and they are showing up fine on the device.

API:33
Phone: Google Pixel 4
APK is a signed release using self-signed certificate (this self signed certificate's hashvalue is also being configured on the metadata of the Profile I'm trying to download, so I'm wondering this shouldn't be a problem during the signature match check)
Also for some context I work in a company that deals in such subscription service management, and I'm testing the possibility of developing an inhouse app to work-around the profiles.

Amazon App Store

There's likely to be a story behind your posting, please elaborate.
Given the default app repository is Google's Play Store service, and that the of number and scope of apps in the Play Store is quite massive compared to the much lessor Amazon Appstore service, there must be some reason(s) as to why you're making such a query.
Don't trust Google? That's a common justifiable topic these days. Using Amazon's Appstore is an alternative, but don't ignore that it is tied to another corporate interest, that for whatever reasons doesn't get the same amount of scorn for its also very extensive data mining on its users.
There are a number of dependable, well established, and verified sources to obtain app APKs if you're adept at side-loading them. APKMirror.com is one. F-Droid.org is a very popular repository that focuses on just Open Source apps.

Oem unlock in build prop

If I have a u.s samsung that doesn't allow
Bootloader unlocking
But I looked inside the build.prop
And it has the line of ro. Oem unlocking =1
The 1 means it's allowed right ? So
In theory if that is already set
All I need is to have the developer options show me the oem unlocking tick right
With that said could I just replace the sec settings.apk with another from another country and put in mine as long as it's android 13 and from samsung
Put it inside the firmware
Flash the firmware through odin
I shouldn't get an error because it's all stock and signed by samsung then I should be able to get it back in developer options
But I also think I read something that stated that developer options ( oem unlocking ) has to be enabled from the bools.xml file inside the decompiled framework-res.apk
Am I crazy or does this sound like it would work ???? Please help

INTERNET

Do you want your credit card details stolen? Or for someone else to get access to your bank accounts?

Do you want your social media accounts taken over and used to scam your friends or family?

Do you want to turn your computer on and find yourself locked out and facing a demand for payment if you want to be able to access any of your stuff again?

Do you want someone to monitor every keystroke you type and collect any sensitive information you enter anywhere?

Do you want your friends' information to be taken by criminals because you thought that you didn't have anything important on your device?

Do I need to go on...?

Help Galaxy Tab A 2019 locked out

Hello,

I have my mother's Galaxy Tab A from 2019. She passed away last summer and I don't know her pattern to unlock the tablet. I have all of her email and Samsung log-in information for those accounts, but because her tablet isn't on my internet, I cannot use the Find My Device to reset the tablet. I had wanted to keep the tablet intact until I was sure there was nothing on it I needed, but at this point I will even take a factory reset if I can just get it functional. I've tried to do the hold down the power and volume down button then switch to the power and volume up combo, the power and volume down to just power combo, etc. and none of them works to allow me to get to the Android menu to do the reset. I am frustrated I can't open this tablet even with her account information. Does anyone have any ideas of something I can do???

TIA for your help.
If you mother samsung account is registered to the tablet, you can try using samsung find my mobile service. Go to findmymobile.samsung.com, login with account credentials and se if you can remotely unlock or reset the tablet from there. Thanks and best wishes

Help Muffled Sound When Live Streaming

Thanks for your advice! I've just order a SmartMike+ external microphone and will see how that works out. I've just been puzzled because the Pixel 2XL mic works so well when recording video but much less effectively when live streaming. Also, friends with iPhones don't have any of the same low volume issues I've experienced with live stream broadcasts.

But in any case I will be sure to check out your links.
My Pixel 6 has the same issue. It worked fine on my Pixel 3, but on the 6 Facebook Livestream sound is muffled. It's clear when recording a regular video though

Australia Z Flip 4 - VOLTE setting missing

My Galaxy A14 5G only has setting for 'wifi calling'. Nothing for HD Voice or switching from 5G to LTE to older networks. I think it's all automatic now. the last smartphone I know that had the setting was my Galaxy S5, where under settings-->connections-->mobile networks it had a toggle for 'Advanced Calling' which was VoLTE compatibility, but that was 2014.

In the U.S., you can still put an active SIM into something that's at least 4G LTE like a Galaxy SII Skyrocket, LG Lucid 3, or LG G2 and you can still do SMS/MMS, data, email, but phone calls fail (they just sit there 'dialing...' until they give up)

Taking Screenshot on Android Smartphones Locally via Python (Without a second smartphone, PC, Wifi or USB Connection)

Hi All,

I want to take screenshots of my Android smartphone screen(not only screenshot of my app but whole screen) locally in background (without a second smartphone, PC , Wifi or USB connection) in my application via Python, but unfortunately I could not find a proper way to do it. I tried following methods but none of them is the right way in my case:

Android Screen Buffer: I guess this is used for screenshot, but I could not achieve to install it. I get following error:
The conflict is caused by: ash 0.3, 0.2 and 0.1 depends on opencv-python==4.1.2.30
but this version does not support any arm base platform. So I cannot install it. Moreover it has also dependencies with ADB tool,
so it looks like wifi or serial connection required.

ADB(Android Debug Bridge Tool): It requires either USB Cable or Wifi connection. The problem is that I do not want that my app users
requires necessary the same Wifi connection(I know internet connection not required but they need to be somewhere around a modem) to be able to use my app.

LADB: This requires also USB Cable or Wifi connection

scrcpy: It has also ADB dependencies. I get no devices/emulators found if I do not start any server from a PC.

Note: I want to implement it necessarily via Python with the reason that the implementation is already done for Windows and MacOS via Cross Platform Python. But if it is impossible with Python is there any other way? if it is so, then which language and library would you recommend? I found some examples via Java but all of them were screen capturing the window within the application not whole smartphone screen.

Thanks a lot in advance.

Environment: Android 11
Prog Language: Python 3.7
