Since 18 Feb 2023, Telegram no longer send verification code by SMS when trying to connect with 3rd-party libraries.

Telegram gives on the official pair which is used in android telegram API_PUBLISHED_FLOOD

I'm looking for a way to fix this story because I know there is a 100% solution.

What did I do?

I added a bunch of different parameters to init connection.

For example, I will take pyrogram code, but telethon has the same results, only there inside the library I had to add params and uncomment lang_pack

init_params = JsonObject(value=[
        JsonObjectValue(
            key="installer",
            value=JsonString(value="com.android.shell")
        ),
        JsonObjectValue(
            key="package_id",
            value=JsonString(value=".telegram.messenger")
        ),
        JsonObjectValue(
            key="tz_offset",
            value=JsonNumber(value=-25200)
        ),
        JsonObjectValue(
            key="perf_cat",
            value=JsonNumber(value=params['PERF_CAT']) # for example 2
        )
    ])

    try:
        app = Client(number,
                     phone_number=number,
                     workdir="soft/sessions",
                     api_id=params['APP_ID'],
                     api_hash=params['APP_HASH'],
                     device_model=params['DEVICE'], // "Huaweinova Y90"
                     system_version=params['SDK'], // "SDK 30"
                     app_version="11.8.2 (57842)",
                     lang_pack=params['LANG_PACK'], // "android"
                     lang_code=params['LANG_CODE'], // "es"
                     system_lang_code=params['SYSTEM_LANG_CODE'], // "es-la"
                     proxy=proxy,
                     client_platform=ClientPlatform.ANDROID,
                     init_connection_params=init_params
                     )

        await app.connect()
        sent = await app.send_code(
            phone_number=number,
            allow_app_hash=True,
            allow_flashcall=True,
            allow_firebase=True,
            current_number=True,
            allow_missed_call=True,
        )

This did not produce any results.

Then I went to look at telegram android source .

Build in 2 modes, release and debug.

Both applications write API_PUBLISHED_FLOOD in the logs.

I got the feeling that Telegram does not document all the parts and something is missing in this puzzle.
