When a Button Stops Responding
You press it — and nothing happens. Or you feel the click, but the phone doesn't respond. Or the button feels mushy, sinking in without the familiar tactile click. This is one of the most common issues customers bring to us: the Home button on older models or the Side button on iPhone X and newer suddenly stops working properly. Sometimes it happens gradually, and sometimes overnight.
Common Causes
Mechanical Wear and Tear
A button is a mechanical component with a limited lifespan. Once it wears out, the contact becomes intermittent: you press it, feel the click, but the phone only responds every other time. We frequently see this on iPhone 6s and 7 after three to five years of active use — completely normal wear and tear.
Dirt and Moisture
This is especially true for the Home button. Over time, dust, grease, and debris accumulate underneath, reducing the mechanism's travel. We once had an iPhone 8 brought in where the Home button could barely be pressed. We opened it up and found a layer of oxidized residue underneath. The owner then remembered the phone had been dropped in water once, but hadn't thought much of it at the time.
Flex Cable Damage
Inside, a thin flex cable connects the button to the logic board. It can fray or tear from drops or if the phone frequently flexes in your pocket. On iPhone 7 and 8, the Home button flex cable is one of the most vulnerable spots during corner impacts.
Touch ID or Firmware Issues
Sometimes the button is mechanically sound, but stops working after an iOS update or after a screen replacement at another repair shop. Apple pairs Touch ID with the logic board, so the system simply rejects third-party hardware.
Side Button on Newer Models
On iPhone X and newer, the Side button also controls Apple Pay, Siri, and powering down. If it stops clicking, the issue is most likely with the internal mechanism or the flex cable. Less commonly, it's the result of an impact or liquid ingress.
What You Can Try Yourself
- Restart your phone. Sometimes a software glitch causes it to hang — a restart fixes it in seconds.
- Remove the case. A tight case or one with built-in button covers might physically obstruct the press. Test the phone without it.
- Turn on AssistiveTouch. This provides an on-screen replacement for the physical button via "Settings → Accessibility → Touch → AssistiveTouch". It's a great temporary fix until you can visit a technician.
- Check for iOS updates. If the button stopped working right after an update, a subsequent patch might resolve it.
We don't recommend trying to clean or disassemble the button yourself. Without experience and specialized tools, it's easy to strip mounting points or tear a flex cable, turning a simple button repair into an expensive screen replacement.
When It's Time to See a Technician
If restarting and removing the case didn't help, the issue is mechanical or related to the flex cable. That requires proper tools and replacement parts.
Replacing the Home button on iPhone 6s, 7, and 8 usually takes us 30–60 minutes and starts from 1,500 rubles. An important detail: on iPhone 7 and 8, the original button with Touch ID is paired to the logic board — we restore that specific button rather than installing an aftermarket replacement, otherwise fingerprint recognition won't work. Side button replacement on iPhone 11–15 is slightly more complex: starting from 2,000 rubles, taking about an hour and a half.
We once had an iPhone 13 Pro brought in where the Side button stopped clicking after a fall at the gym. Cosmetically, there wasn't a single scratch, but inside, the flex cable was pinched by a shifted chassis frame. We realigned the frame, replaced the flex cable, and everything worked like new.
