Apple has already started testing iOS 15.3 firmware, with some developers saying that the new firmware appeared faster than expected.
According to the official description, the iOS 15.3 beta mainly fixes some bugs as well as some security vulnerabilities such as Safari history vulnerabilities.
Sources say that Apple promptly released iOS 15.3 beta in response to pink screen situation reported by iPhone 13 users. Apple has previously stated that this is definitely not a hardware issue and should be fixed with a software update.
On the Chinese platform Black Cat alone, according to the source, there are already more than 36,000 complaints from iPhone 13 users. At the moment, resetting the phone to factory settings and updating to the current version of iOS cannot solve the problem.
Users confirm that in addition to the pink screen, there are clearly noticeable stutters and afterimages on the smartphone. Some phones will reboot on their own.
