iPhone Screen repair and How to Fix Them Safely
It usually starts with a single drop — that slow-motion tumble from your hand to the floor. You pick it up, praying the screen is still intact, only to find a spider-web crack staring back at you. Sound familiar?
iPhones are known for their premium build, but they’re still delicate machines packed with sensitive components. From cracked screens to battery issues and water exposure, iPhone damage is among the most common repair requests at stores like Blackapple Cellular, where technicians see hundreds of cases each month.
In this guide, we’ll walk through the most frequent iPhone problems, their causes, quick at-home checks, and the safest repair options — so you know exactly what to do when trouble strikes.
1. Cracked or Broken Screen
Why It Happens
Drops and impact are the obvious culprits. Even with Apple’s Ceramic Shield, one bad fall on concrete can crack the display or damage touch sensors underneath.
How to Fix
- Do Not Press Hard: If touch still works, avoid applying pressure — this can worsen internal damage.
- Use a Tempered Glass Temporarily: It prevents shards from falling and protects your fingers.
- Professional Repair: Screen replacements should always be handled by certified technicians who use genuine displays with proper calibration.
- At Blackapple Cellular: Every screen is tested for brightness, touch accuracy, and colour fidelity before installation.
Prevention
Invest in a shock-proof case and tempered glass from day one. It’s far cheaper than a ₹15,000 screen replacement.
2. Battery Draining Fast or Swelling
Signs of Trouble
- Battery health below 80 %
- Phone heats up while charging
- Sudden percentage drops
- Slight bulge on the back or screen lift
Why It Happens
Constant over-charging, cheap cables, or exposure to high temperatures degrade lithium-ion cells.
Safe Fix
- Check Settings → Battery → Battery Health & Charging.
- Disable “Background App Refresh” for unused apps.
- If the issue persists, get a battery replacement using OEM-grade parts.
- Avoid online “DIY battery kits” — improper fitting can short-circuit the motherboard.
At Blackapple Cellular, replacements are done under controlled static-free conditions, ensuring full safety and warranty retention.
3. Water or Liquid Damage
Common Scenarios
A spilt coffee, a rainy commute, or dropping your phone in a sink — water finds its way into speakers, charging ports, and logic boards.
Immediate Steps
- Turn off the phone immediately — don’t press any buttons.
Â
- Do not use a hair dryer. Heat can warp components.
Â
- Gently wipe the exterior and keep the device upright.
Â
- Bring it to a professional repair shop within 6–12 hours.
Â
What Professionals Do
Technicians open the device, remove the battery, clean corrosion using isopropyl solution, and dry it in a controlled heat chamber.
At Blackapple Cellular, specialised ultrasonic cleaning restores water-damaged boards in 70 % of cases.
4. Charging Port or Cable Issues
Symptoms
- Charging cuts in and out
Â
- iPhone doesn’t recognise cables
Â
- “Accessory not supported” warning
Â
Possible Causes
Lint or dust clogging the Lightning port, or damaged internal pins from rough cable use.
Fix
- Use a soft brush or compressed air to clean (never metal pins).
Â
- If corrosion is visible, professional microsoldering may be required.
Â
- Certified shops like Blackapple Cellular offer port cleaning and replacement within an hour.
5. Camera Malfunctions
Common Problems
- Blurry images or a foggy lens
- Shaking viewfinder (stabiliser failure)
- “Camera not available” error
Why It Happens
Physical drops, moisture, or magnetic interference from third-party cases can misalign camera sensors.
Fix
- Restart and test in Safe Mode (if on Beta iOS).
- Avoid third-party camera apps if lagging occurs.
- For hardware issues, get a camera module replacement using genuine parts — Apple’s camera calibration requires precision equipment.
At Blackapple Cellular, technicians realign sensors and run post-repair calibration using Apple-grade diagnostics.
6. Speaker or Microphone Problems
Indicators
Calls sound muffled, or the mic doesn’t pick up your voice during recordings.
Solutions
- Clean the grill gently with a soft brush.
- Update to the latest iOS (software glitches can affect audio).
- If hardware-related, speaker mesh or mic flex cable replacement solves the issue.
Pro Tip: Avoid poking pins or needles into speaker holes — it tears the mesh and ruins sound quality.
7. Face ID and Home Button Failures
Why It Happens
Drops, liquid ingress, or unauthorised screen replacements can disable Face ID modules or the Touch ID sensor.
Fix
- Run diagnostics in Settings → Face ID & Passcode.
Â
- For hardware faults, the TrueDepth camera or Touch ID flex must be replaced and paired.
Â
- Only professional technicians with pairing tools can restore full functionality.
Â
At Blackapple Cellular, every biometric repair is followed by security verification to ensure safe authentication.
8. Software Glitches and Boot Loop
Symptoms
- Apple logo stuck on boot
- Apps crashing repeatedly
- Sudden restarts
Quick Fixes
- Force restart your iPhone.
- Update via iTunes or Finder.
- If the issue persists, reinstall iOS (DFU mode).
When to Seek Help
If the phone remains stuck even after restoration, it’s likely a logic board issue. Professional micro-soldering or chip re-balling may be required, something only a certified lab should perform.

FAQs
Q1: My iPhone has minor cracks, but it works fine. Should I replace the screen?
Yes. Even hairline cracks can worsen or affect touch sensitivity over time.
Q2: Is it safe to charge a swollen battery?
No. Unplug immediately and visit a service centre — swollen batteries may burst.
Q3: Can I use rice to dry a water-damaged iPhone?
No. Rice absorbs surface moisture only and leaves dust residues inside. Get it professionally dried.

Only if OEM-grade. Cheap copies reduce brightness, touch response, and resale value.

Yes. All repairs include a limited warranty on parts and labour.
