Recently Apple updated iOS 15.4 Beta4, version number 19E5235a. Although it is a beta version, the online review reputation of the version is still good, and even some netizens say that the fluency is comparable to the official version. To this end, I specifically found a few users of different models to see how they felt after the upgrade.
a: 12PM, from iOS15.4 Beta1 all the way to Beta4, the most obvious change is to wear a mask to unlock more silky, unlock speed is similar to not wearing a mask, but the fluency is slightly worse than Beta3, especially in quick browsing.
B: I have to say that several beta versions of ios15.4 are very good, upgraded B3 and B4, it is really very practical to unlock without taking off the mask, that is, my 12Pro endurance has declined, and then use a few days to see.
c: 13 upgrades the fluency and battery life feel no change, wearing a mask can also unlock this is very good, but I want to know how to turn off the lock screen play frame, is it difficult to shut down every day to restart?
D: iPhone11 has been updated, ios15.4b4 is very smooth is true, but the altitude in the compass is missing after the update, have you encountered the same situation?
e: After updating 15.4 Beta4, the play box of the lock screen interface cannot be closed, and it needs to be restarted to unlock, but the fluency is really good, iPhoneX.
It can be seen that the fluency of iOS15.4 Beta4 is indeed very smooth as stated on the Internet, but a small number of users cannot turn off the play box of the lock screen after the update, which can be solved by backing out of the background. So iOS 15.4 Beta4 is indeed a version worth upgrading.
