iOS 15.1.1 official version released: fixes major bugs, call drop signal problem completely solved

Apple pushed the ios15.1.1 genuine system update to official version users early this morning. The internal version number is 19B81. This update is mainly for iPhone12 and iPhone13, and solves major bug issues such as dropped calls and call quality.

This time, the official announced that the content of this update is the same as ios15.1, but it is only pushed to iPhone12 series and iPhone13 series users.

Many users have previously reported that the iPhone 12 series and iPhone 13 series have experienced signal problems such as dropped calls during calls, and there are also problems with call quality, including earpiece noise. Some users of iPhone 12 and iPhone 13 series models also said that similar bug problems have not occurred, so this is not a common problem, it may still be a batch problem, but if the above-mentioned bug problems occur, then the official version of ios15.1.1 can be updated this time.

Summary of netizens' experience of upgrading to the official version of ios15.1.1:

1. The delay in sending voice messages via WeChat seems to have been fixed.

2. I got up to go to the bathroom and found that there was actually three bars of signal in the bathroom. It was the first time that I had a three-bar signal when I went to the bathroom after using the iPhone 13 Pro for almost two months. Before, I would lose one bar of signal when I went to the bathroom!

3. I have never encountered a call drop, but when making calls on China Mobile, there is often a long period of no response.

4. It runs much smoother after the update. It seems that these hundreds of megabytes are more than just updating the baseband.

5. The baseband version is 2.11.04, which should be updated.

6. I feel the same way. It is much smoother now. I wonder how it consumes power.

7. The signal feels better and there is no noise during calls.

8. The line was dropped during a previous call, and it didn’t reappear after I made a few calls.

9. I've never experienced call drops before, but this update seems to be smoother.

10. Recently there have been bugs when making phone calls, so I just upgraded it, and after the upgrade it seems that the bugs no longer exist.

11. The baseband has been updated, and there is no call bug problem for the time being. It remains to be seen. The battery life is not yet noticeable, and I need to try it for two days.

12. The signal has been significantly improved, it is smoother, and the heating condition has been improved.

13. The app used to crash, but now it doesn’t. The signal is still good, at least there is no problem with one bar of signal.

14. The heating situation has improved, the signal has improved, and the system fluency has become smoother.

The above is a summary of netizens’ experience of upgrading to the official version of ios15.1.1. Each model has different feelings, but the current major bug is the call drop signal problem of iPhone12 and iPhone13 series. At present, some netizens have reported and confirmed that it has been fixed, so friends who still have these problems can choose to upgrade!
