In 2019, the official Telegram client didn't have chat folders so I was using a Telegram client made by an Iranian dude (Telegram was extremely popular in Iran and Iranian clients were the most feature-rich).
Signal doesn't have a proper backup/migration mechanism yet when adding new devices.... Whatsapp is more complete. Idk, maybe Element too but haven't used it recently
>Not to mention the app is a buggy mess. At least on iphone.
If you think it's buggy on iPhone you have no idea what's going on on Android. The iOS venison is actaully the "polished " one as Signal devs daily drive iPhones.
Have someone call you on Signal. Missed calls galore. Also texts. It just dozez all the time (despite having been configured in Android to not let it sleep) and texts come late and calls get missed.
It doesn't "doze all the time" here, seems like you're blaming Signal when it's your phone's power management software not working as described.
The only people I know that have this kind of issue with Signal are all on Huawei phones, we've configured them and it's worked for a while but Huawei only seem to care about letting Facebook/Whatsapp/Teitter/etc.. run properly.
Like the other poster mentionied, you might have missed, that you missed things. It is sadly unreliable for me, too, which is just unacceptable with a messenger.
Telegram in 2019 was perfect. None of the features added since then have been that great.
