On the iPhone 7, if the Home Button is damaged it can cause a long boot cycle. In addition, whatever event caused the damage to the Hb may also have caused other logic board issues, particularly to the Audio IC.

The iPhone 7 series of devices have proven to be very unreliable, suffering from flex-based issues similar to the iPhone 6 Plus (Touch Disease). On the iPhone 7, the fault line runs along the top of the SIM card reader and affects the Baseband CPU and Audio IC. Any short copper traces running perpendicular to the fault line while connecting to micro-BGA pads, is subject to failing.

On the Audio IC, this particularly affects the C12 pad/trace although there are 4 pads/traces along the fault line. Of those four, the C12 pad (I2S_AP_TO_CODEC_MCLK) is the most critical as it is a communication protocol line between the CPU and the Audio IC. ''''

Here are the typical symptoms, as collated by the repair community:

  1. Voice Memos app / Loudspeaker on call - greyed out
  2. Siri doesn’t hear you / Caller can’t hear you
  3. Most other Audio related issues that aren’t solved by modular replacements
  4. Long boot times (3-5 minutes)
  5. iTunes detects the phone but stuck on the Apple Logo

Do you mean touch as in touching the screen or the TouchID. If the HB is damaged (TouchID), only Apple can repair/replace it.
