💡FAQ:
Question 1: Can I use a hair dryer instead of a heat gun for this repair?
Answer 1: Yes. A hair dryer on high heat works, but be sure to warm the surface enough to soften the adhesive without damaging the phone.

Question 2: Do I need to replace the adhesive tape after opening the iPhone 16 Pro Max?
Answer 2: Once the original seal is broken, replacing the old adhesive tape is recommended to restore water resistance.

Question 3: How do I keep track of all the screws during disassembly?
Answer 3: A magnetic mat is highly recommended. It holds screws in place and helps you remember where each screw goes.

Question 4: Should I disconnect the battery before removing other components?
Answer 4: Yes. Always disconnect the battery first to avoid short circuits or accidental damage to internal parts.

Question 5: Is it safe to reuse the old button cable?
Answer 5: If your volume and action buttons are completely unresponsive, a new cable is usually required to fix the issue.
