In 2016, people who experienced touch problems encountered anotheriPhone6 "Cycle Restart" failure. The explanation given at the time of the survey was that due to the bending of the mobile phone, the solder joints of the touch originals were loosened.

Although this structural problem was resolved after the iPhone 6s, the recent emergence of a large number of loop restart failures seems to be due to the same reason.

Federico Cerva from London pointed out that poor audio chip contact is likely to be caused by small crystal grains.

However, Jessa Jones from New York believes that during normal use, the phone will cause this failure due to multiple bending pressures.

However, for whatever reason, the end result is the same:

First of all, connecting the pads of the audio chip can cause problems, such as voice memos or speaker failure (the icons are grayed out).

Then, when the user tries to restart the phone, he will find that the system card is stuck in the startup interface (only look at the Apple Logo in a daze).

In this example, we found that only the re-welding of the soldered components can solve the problem of the stuck interface.

However, the problem also came - who should be responsible for this maintenance?Given that most of the affected models have been insured, unlucky consumers can only seek unofficial third party repair shops.

As for Apple, one representative claimed that the company is investigating "very few reports."To think about the benefits, this part of the consumer still hopes to receive extended warranty support.
