Fernschreiber is a Telegram client for Salifish OS

Apparently this app is Vibe-coded now.. and the author didn't even bother to write about in the description. I see now there is Yast fork, which seems to be made by a human, guess I will switch to it.

Thanks for the hint, simply forgot to mention it. I added a note in the same way as for Lauscher. And well, it's great to have choice, so if other clients fit better for whatever reasons, simply use them, that's how open source works. :)
Regarding the AI discussion overall: IMHO, these are simply new tools to make devs' lives easier and much more efficient. For me personally, I couldn't have continued this projects for probably a long time without them. In the long run, I'm sure they will become as normal as fancy editors, IDEs, compliler toolchains etc. are today. And to be honest, they already are in the industry. Down the road, I hope, there will be competitve models and tools which are entirely open source. But given the current speed of innovation, this probably won't take long...

I see in Yast description it says that Pull Requests weren't accepted for more than year. But that is even before IA, which should not be needed for just clicking Accept.. And I read online also articles that Claude code is "sloppy" even if checked by human and human-written code is usually better than it... Plus Claude is american which is not great for a European OS like our Sailfish

Well, at least I do much more than just clicking "Accept". Personal taste, the willingness to craft something solid and with high quality and the desire to understand the code which you're merging into the codebase doesn't simply go away so easy if you have more powerful tools. Since a few months, the code that is generated by frontier models is in many case of very high quality - a bit chatty sometimes, but well, who's perfect? And I'm happy to jump on a European model once they become competitive. Until then, we need to make the best of living in an imperfect world, typing this on a device whose components are proabably mainly made in China for instance.

If the number hasn't been registered yet with Telegram, it probably won't work. Needs to be done with an official client first. If already registered, the code reached another client where you are registered.

Hi, for me, the updated app gives error when opening. Xperia 10 II, latest OS.

Weird, this should normally only occur if the database was already upgraded to a later version of TDLib. Please remove ~/.local/shrare/de.ygriega/fernschreiber and restart the app. You need to register again afterwards.

Cool, update finally! But can't start it - no proxy feature support :( Telegram is blocked in some countries :(

Fantastic seeing a new update, thank you! I'd like to contribute some translations, would you be able to set up Hosted Weblate (https://hosted.weblate.org) to let translators contribute more easily (and without a GitHub account)?

Need to check that. My time is severely limited therefore I can't promise it. GitHub would still be the preferred option for now.

Appears to be broken since yesterday - stuck on "updating content" status. Old GitHub issue indicating TDLib incompatibility due to server-side changes. Anyone else experiencing this?

Great app! When reading messeges the readed one get automatic status read ecept it a pull is the last message. Them there is always left one unteadef message.
..... and I'm really missing the audio call function. A lot of Telegram users are using it. Even support is done by this function. And to be honest Yollagram has not such a good usabillity than Fernschreiber.

Thank you, for great app! Please, may be not so hard to enable swipe left-right in user's photo's in account info? Now we need to open photo, then swipe back, then swipe to next preview, tap on it, open and again swipe back etc..

Love the app, and I'm using it on a daily basis - thanks a mil for Fernschreiber!
At the moment, there is only one feature I'm missing: folders! I've only discovered them recently in the desktop client, because I've joined an organisation that uses a lot of Telegram-channels to categorise communication, and being able to sort them into folders was a real improvement. Is this maybe a feature you might consider adding at some point in the future? (I have no idea how difficult that would be - maybe it's not feasible...)

That's one app to showcase for nice design and nice usability on SFOS! Great work!
Unfortunately you cannot get into groups from the browser, need the android app to do that. Can be solved?

I love it. But today I sent an audio notice and the receiving person couldn't hear anything. Sending such a message to myself works great.

That's due to a missing codec in SFOS. Haven't had time yet to build in the missing one in Fernschreiber.

What codec we have to install manually? Can you add it into next version please? :)

Great app. Only thing i'm missing currently is the ability to view all media of a conversation in a gallery form.

Do you think comments will be enabled in next releases. I like this app very much but lacks of comments reading and answering, as all the others based on tdlib
