A new free jailbreak tweak dubbed RedFailedMessages by iOS developer NeinZedd9 has the goal of making it easier to discern between successful and failed messages by turning the entire chat bubble of a failed message red.
Once you install this tweak, you’ll notice there aren’t any options to configure. Instead, the tweak takes effect immediately.
As shown above, you’ll no longer get just a negligible red exclamation mark badge beside your green or blue chat bubble. Instead, you’ll get a solid red chat bubble along with the stock alert, which is significantly more noticeable than the former.
The tweak doesn’t impact the Messages app in any other way besides colorizing the chat bubble of a failed message, so other Messages app features continue to work how you’d expect. As soon as you send a failed message successfully, the chat bubble then turns the correct color – blue for iMessage or green for SMS.
You can download the tweak for free from Cydia’s BigBoss repository. The tweak works on jailbroken iOS 10 devices and is open source on the developer’s GitHub.
