This seems to confirm that the software is almost entirely the same, and that the very first iPhone 16 series phones which had been loaded with software in readiness to be shipped out for sale on September 20, had the earlier build which was superseded by the Sept. 16 build.

The reason for this touchscreen issue? Because of the much thinner bezels of the iPhone 16 Pro and iPhone 16 Pro Max display, the accidental touch rejection algorithm seems to be more sensitive than before.

The latest iPhones are out and some users are reporting a problem with the touchscreen. It looks like it might not be restricted to the newest models.

Apple's newest iPhone lineup, the iPhone 16 series, has only been available for a short time, yet some early users are reporting touchscreen problems. According to several posts on Reddit, the issue seems to occur when users rest their thumb or finger near the Camera Control area on the display.
