Twitter recently launched Twitter Blue for Android users, allowing them to change the app icon and undo tweets at any time. Twitter Android’s version number is 9.76.0-release.0 has implemented some deeplinks for Twitter subscription to perform direct action, and some of those deeplinks are not being validated or don’t have custom permissions set if the user has a subscription or not, so it is possible to use the change icon, custom navigation, and early access features without a subscription using the below deeplinks:
twitter://subscriptions/settings/extras
twitter://subscriptions/settings/early_access
extras deeplink gives access to change icon and change custom navigation and early_access deeplink gives access to features like undo tweets with custom timing.
Steps To Reproduce:
Launch below deeplink using adb to access app change flow :
adb shell am start -d "twitter://subscriptions/settings/extras"
Launch below deeplink using adb to access undo tweet feature:
adb shell am start -d "twitter://subscriptions/settings/early_access"
