This issue occurs on Telegram's side. Users have reported this before. Unfortunately, the only fix is reinstalling the messenger.
This issue is resolved by removing file manager updates and clearing the cache.
There can be several reasons: · System component updates may not work on custom ROMs. · Your version may be newer! Then the update won't install. · The region of your firmware and app differs from the update region. Except for rare cases, we only publish global versions. · Your system is outdated and may not support current versions. · Make sure the update is intended for your device type (Smartphone/Tablet/Mix Flip) If you think the problem is something else, write to us in the chat.
Carefully read the error text, it explains the cause, or write to us in channel PM.
Write to us in channel PM, and we will try to quickly solve the problem. Our database has more than 350 devices, and we strive to keep it updated, but sometimes inaccuracies are possible.
We are sorry, but not all devices are included in this list. It only affects the availability of information about which Android version your device will receive.
Check the lists and make sure the device has not yet received the latest Android version listed there. If the versions match, it means the app is informing you about the end of new version development and is displaying correctly. If the device has not yet received the latest version, write to us in channel PM to verify the database. We will quickly resolve the issue.
If you have Chinese firmware — disable restrictions for the app and allow it to run in the background. Our app is generally designed to sleep in the background and activate only when it receives a signal about a new version. For notifications to work correctly, the app checks the language and installed version, so we recommend disabling all power restrictions and enabling auto-start. If you have a newer version installed, an incompatible device type, brand, or your device does not meet minimum requirements, the notification will not appear.
This is a common issue; you need to allow Telegram to open its internal links directly in the app in the application settings.
