TelegramApp-specific values come first
An Android version, APK size or package is an app fact only when an exact operator/app source supports it. Do not treat a generic baseline as a verified specification.
iOS is a separate platform
An Android APK does not install on an iPhone or iPad. An iOS link is valid only when the same operator’s separate App Store identity matches.
Keep protection enabled
Keep Android and Google Play Protect updated. Do not leave unknown-source installation enabled; stop at a suspicious prompt.
