What\u2019s more, iPhone touch ID of iPhone 6 and later versions are bonded with CPU (iPhone 6s home button not working), and Home Button replacing by users has a destructive effect on touch ID fingerprint sensor function. The fact is that about 80% of iPhone Touch ID failures are caused by damaged home button flex.\u00a0Well, this time REWA come up with a new solution regarding the damaged home button flex. Check it out by yourself now.<\/p>\n<p style=\"line-height: 1.7;\"><img decoding=\"async\" src=\"https:\/\/s.rewa.tech\/image\/cbb4e83a-1f9d-4920-8ab9-2077e202e609-1-6.jpg\" alt=\"How to Restore iPhone Touch ID With Home Button Flex Repairing\" title=\"\"><\/p>\n<p style=\"line-height: 1.7;\">Restore iPhone Touch ID With Home Button Flex RepairingPower on and test. &#8220;Unable to activate Touch ID on this iPhone&#8221;.
