Cracked the back of your Samsung Galaxy? While not as critical as screen damage, broken back glass creates risks you shouldn't ignore. Here's what back glass repair costs, why you should fix it, and what happens to wireless charging.
Book Back Glass Repair · From £69Book nowWhy Samsung Uses Glass Backs
Samsung switched from metal to glass backs for three practical reasons:
- Wireless charging: Metal blocks wireless charging coils - glass doesn't
- 5G signals: Glass allows better antenna reception for 5G frequencies
- Premium feel: Frosted or glossy glass looks and feels premium
The trade-off is fragility. Glass cracks when dropped, especially on hard surfaces. Samsung uses Gorilla Glass Victus 2, which is tough but not indestructible.
Risks of Ignoring Cracked Back Glass
Immediate Risks
- Cuts and irritation: Sharp edges can cut fingers
- Further cracking: Damage spreads with use and temperature changes
- Glass fragments: Pieces can fall out over time
Long-Term Risks
- Water ingress: Broken glass compromises IP68 water resistance
- Dust and debris: Internal components exposed to contamination
- Resale value: Significantly reduced if selling or trading in
Case As Temporary Solution
A case covers the damage and prevents cuts, but doesn't solve the underlying problems. Water resistance is still compromised. For temporary protection, a case is fine - but repair is the proper fix.
Back Glass Repair Options
Full Back Glass Replacement
The proper repair - completely removes cracked glass and installs new genuine Samsung back panel. Restores original appearance and sealing.
Back Housing Replacement
For some models, replacing the entire back housing (glass + frame) is more efficient. This is often done for older models where separating glass from frame is difficult.
UK Repair Costs
| Model | Back Glass Repair |
|---|---|
| Galaxy S24 Ultra | £99 |
| Galaxy S24/S24+ | £89 |
| Galaxy S23 series | £79-89 |
| Galaxy S22/S21 | £69-79 |
| Galaxy A series | £59-69 |
Wireless Charging After Repair
Proper back glass repair fully restores wireless charging. The wireless charging coil sits just beneath the back glass - as long as:
- Genuine Samsung glass is used (correct thickness)
- Coil isn't damaged during removal
- Proper adhesive spacing is maintained
Cheap plastic backs or incorrect glass thickness can interfere with wireless charging efficiency.
Water Resistance Impact
Cracked back glass immediately voids your phone's water resistance. After proper repair:
- New waterproof adhesive is applied
- Seals are tested where possible
- IP68 rating is functionally restored
IP Rating Reality
Even with perfect repair, we don't guarantee the same IP68 rating as factory. IP ratings degrade over time even on undamaged phones. Treat repaired phones as water-resistant, not waterproof.
Frequently Asked Questions
Frequently Asked Questions
A case covers the damage but doesn't fix it. Cracked back glass can worsen over time, allow moisture in, cut your fingers, and continues to look damaged when you remove the case. For phones worth keeping, repair is the better solution.
Yes. We use proper glass replacement with correct thickness and materials. Wireless charging works exactly as before. Cheap plastic covers or incorrect glass can interfere with wireless charging coils.
Three reasons: wireless charging (metal blocks it), 5G antenna performance (glass allows better signal penetration), and premium aesthetics. The trade-off is fragility - glass backs crack when dropped.
Generally yes. The back glass is separate from critical components and uses adhesive that can be heated and removed. Screen repairs involve more sensitive display connections. Back glass repair takes 60-90 minutes.
