Expert Advice & Tips
1. Common causes of this issue:

- Charging port debris, corrosion, or physical damage preventing safe charging.
- Software glitches causing unresponsiveness or random reboots.
- Display faults such as dimness, colour distortion, or touch failures.
- Water exposure or high humidity triggering sensor or circuit faults.
2. Prevention tips:

- Use official or certified charging accessories only.
- Protect from moisture with a rugged case and splash protection.
- Avoid exposing the device to extreme temperatures or rapid temperature changes.
- Regularly back up data to reduce risk during repairs.
3. When to repair vs replace:

- Keep software up to date and run periodic diagnostics.
- Schedule a follow-up check if performance seems slow or erratic.
What Our Customers Say
Alex from Marsh, Huddersfield: I dropped my Galaxy J4 Core and the screen cracked badly. iRepair Guys Marsh diagnosed it in minutes and replaced the screen in under an hour. The build quality is superb and the price was fair—the Apple Store would have charged twice as much. Fast, friendly, and spot on with what they promised.
Ravi from Almondbury, Huddersfield—business owner: Our team relies on mobile phones daily. iRepair Guys came to our Town Centre office, fixed two devices on the same day, and kept downtime to a minimum. Reliable service, clean work, and a substantial business discount compared with retail options.
Mia from Lindley, Huddersfield: As a student, price matters. They swapped out my Galaxy J4 Core battery quickly, cheaper than Apple, and with a student discount. No hidden costs, and the phone works like new. Great for exam season when budgets are tight.
Priya from Dalton, near Huddersfield: I used their mail-in service; I sent my phone and it came back working within two days. Communication was clear, updates kept coming, and the repair quality is excellent.
James from Moldgreen: I run a small design studio and needed a same-day repair on a client device. iRepair Guys sent a technician to our office and fixed the screen the same day. Excellent for businesses, transparent pricing, and the repair held up under daily wear.
The Patel family: We had multiple devices repaired across Marsh and Almondbury and saved with loyalty discounts. They fixed phones and tablets quickly, kept to appointment times, and the whole family is now loyal customers.
