How is the signal of iPhone 12 after updating to iOS 17.3?

After many iOS 17.2.1 users updated to the latest iOS 17.3 version, users generally reported that the signal quality has been significantly improved.

It seems that this update has also optimized and improved the signal reception and processing system to provide a more stable and faster data connection experience.

But this does not mean that iPhone12 is suitable for this system. It is recommended that iPhone12 users not update iOS 17.3, because iOS 17.3 will have other burdens on iPhone12, such as power consumption and card changes.

Therefore, it is recommended that everyone keep their original system.
