Check the model number in your device settings, or bring it in and we will confirm the exact LG G4 before any work begins. If you are unsure which repair you need, our team will advise.
Before you book
- If there is any sign of liquid inside, a screen alone may not fix everything, and we confirm first.

- If touch was already patchy before the glass cracked, that can be a separate fault we will test for.

Frequently Asked Questions
How long does a LG G4 Screen (Glass and LCD) screen replacement take?
Most LG G4 Screen (Glass and LCD) screen replacements are completed the same day when the part is in stock, often within a couple of hours of dropping in at our Liverpool Street workshop in London. We inspect the device first, and if a part needs to be ordered in or we find wider damage, we confirm a realistic timeframe with you before starting. Mail-in repairs are turned around as quickly as the post allows once your device arrives.
Check current turnaround and reserve a slot on our booking page.
How do I know it is the screen and not another fault?
Cracked glass, lines, flicker, dead patches, discolouration or unresponsive touch while the device still powers on almost always points to the display assembly. On most modern devices the panel and the touch layer are part of one assembly, so cracked glass and touch faults are usually solved by the same replacement. If the device will not power on, has been exposed to liquid, or shows more than one symptom, a short diagnosis confirms the fault before you commit.
If you are not certain, it is worth booking a quick diagnosis first.
What quality of screen do you use for the LG G4 Screen (Glass and LCD)?
We fit a high-quality replacement display chosen specifically for the LG G4 Screen (Glass and LCD), then calibrate and test it before return. The replacement restores full touch response, brightness and colour, and it carries our 12-month warranty. If more than one option becomes available for your model, we will explain the choice clearly before any work begins.
See how we fit and test each repair on our how we work page.
Does the fingerprint reader still work afterwards?
In most cases, yes. We test the fingerprint sensor along with touch, brightness and colour before your LG G4 Screen (Glass and LCD) is returned. Where the fingerprint reader sits under the display, it can occasionally need recalibration after a screen change, and we will tell you if a separate part is involved. Any sensor behaviour is checked as part of our standard post-repair testing.

Do I lose my data during a screen repair?
No. A LG G4 Screen (Glass and LCD) screen replacement is a hardware-only repair and does not require us to wipe or factory reset your device, so your files and settings stay as they are. We still recommend keeping a recent backup before any repair, simply as good practice in case the device has damage beyond the screen. Nothing about the screen procedure itself touches your storage.
Bring the device in and we will confirm everything before starting.
What warranty is included?
Every LG G4 Screen (Glass and LCD) screen replacement includes a 12-month warranty covering both the fitted display and our workmanship. If a fault develops with the part or the fitting within that period, we put it right at no extra cost. The warranty does not cover fresh impact damage, liquid exposure or an unrelated fault that appears later, which we always explain clearly before you book.
Our team is happy to help before you book.
