Cracked glass, unresponsive touch, and a dead or discoloured display all look like different problems, but on a Moto G they're almost always fixed by the same part — the screen assembly, which combines the glass, digitiser (touch layer) and LCD/AMOLED panel into one unit. Knowing which symptom you have still matters, because it confirms you're diagnosing the right fault before you spend money, and it helps you rule out the rarer cases where the screen genuinely isn't the problem. Here's how to tell them apart with confidence.
Match your symptom
| What you see | What's actually damaged | Fix |
|---|---|---|
| Visible cracks in the glass, but the display and touch both still work | Outer glass only — cosmetic for now, but will worsen and risks cutting fingers | Screen assembly replacement (glass isn't typically sold separately from the digitiser on Moto G) |
| Glass intact, but taps register in the wrong place or don't register at all | Digitiser (touch layer) failure, often from impact even without visible cracking | Screen assembly replacement |
| Coloured lines, dark patches, or a partially blank display | Damaged LCD/AMOLED panel | Screen assembly replacement |
| Display works but touch is unresponsive only in one specific area | Localised digitiser damage, often near a drop-impact point | Screen assembly replacement |
| Screen completely black with no image at all, but the phone otherwise responds (vibration, sound) | Full display failure — see our dedicated black screen diagnosis guide | Screen assembly replacement |
| Screen shows a stretched or distorted image after a drop | Panel damage, likely from the same impact that may have also affected the frame | Screen assembly replacement; check the frame for visible bending too |
Why it's (almost always) one part, not separate glass/touch/LCD parts
Direct answer: on the vast majority of Moto G models, the glass, digitiser and display panel are bonded together as a single assembly rather than sold as separate replaceable layers — so whichever of the three has failed, the fix is the same replacement part. This is actually useful news rather than a limitation: you don't need to pinpoint the exact failure mode with lab-grade precision, just confirm it's the screen and not the battery or motherboard, which the checks below cover. Some independent repair specialists do offer glass-only re-lamination services that separate a cracked outer layer from a working digitiser and panel underneath, but this is a specialist process, not something available as a standard consumer part, and isn't something we offer or can recommend a specific provider for.
Ruling out battery or motherboard faults first
Before ordering a screen, quickly confirm the phone is actually receiving power and responding to input elsewhere in the system: check for a charging light or vibration when you plug it in or call it from another phone. If there's genuinely no response at all — no light, no sound, no vibration — the fault is more likely the battery or motherboard, and a new screen won't resolve it. Our black screen diagnostic guide covers this specific check in more depth, including the torch test for identifying a failed backlight versus a fully dead panel.
A note on cracked glass specifically
If your only symptom is a visible crack with display and touch both still working normally, you have some flexibility on timing — it's not an emergency repair in the same way a fully dead screen is. However, cracks reliably worsen over time as glass continues to spread under everyday flexing and temperature change, and moisture or dust can work through a crack to reach the digitiser or panel underneath, eventually causing the touch or display faults covered elsewhere in this table. A tempered-glass screen protector applied over an existing crack slows this process and reduces injury risk from sharp edges while you decide when to repair, but it doesn't stop the underlying damage from progressing.
Once you've confirmed it's the screen
Find your exact model and current pricing in our Moto G screen replacement guide, or go straight to the Moto Screen Replacement collection. Not sure of your exact model? Use our model identification guide first — Motorola's screens are not interchangeable between the Power, Play and Plus editions of the same generation, so this step matters before you order regardless of which symptom brought you here.
Why digitiser faults are so often mistaken for "the phone is broken"
Of the three failure types in the table above, digitiser damage without visible cracking is the one most likely to be misdiagnosed by someone unfamiliar with phone repair, because there's nothing to see. A phone with unresponsive touch and an intact-looking screen understandably reads as "something deeper is wrong" — a software fault, a dying phone generally — when in most cases it's a straightforward, single-part hardware fix. If your Moto G's touch has stopped working (fully or in specific areas) following any drop or impact, even a minor one that didn't crack the glass, the screen assembly is the first and most likely place to look before assuming a more serious or expensive fault.
What buying the wrong diagnosis costs you
Getting this diagnosis right before ordering matters because Moto G screens generally aren't returnable once fitted, and the phone won't work any differently after a screen replacement if the actual fault was elsewhere. Running through the checks in this guide — confirming signs of life, matching your specific symptom against the table above — takes a few minutes and directly protects you from an unnecessary purchase. If after these checks you're still uncertain which category your symptom falls into, it's reasonable to get a second opinion from a technician before committing to a part, particularly for the boot-loop and no-response edge cases that genuinely can't be diagnosed from the outside with full certainty.

Frequently asked questions
Can I just replace the glass without replacing the whole screen?
On most Moto G models, no — the glass, digitiser and display are bonded as one assembly, so a cracked-glass repair means replacing the full screen unit. Specialist glass-only re-lamination exists as a separate professional service in some markets, but isn't a standard consumer part.
My touch doesn't work but there's no visible crack — is it still the screen?
Yes, most likely. Digitiser damage from an impact doesn't always show as visible cracking on the surface, particularly if the impact was concentrated on one edge or corner.
How do I know if it's the screen and not the battery?
Check for any sign of life — a charging light, vibration, or sound when called from another phone. If there's genuinely none, the fault is more likely the battery or motherboard rather than the screen.
Is it safe to use a Moto G with a cracked screen in the meantime?
Generally yes if touch and display both still work fully and there are no sharp edges, but fit a screen protector and don't delay indefinitely — moisture and dust ingress through the crack can turn a cosmetic issue into a functional one.
What causes touch to fail in only one specific area of the screen?
Localised digitiser damage, usually from an impact concentrated at that point — the touch-sensing layer is grid-based, so damage in one section can affect input there while the rest continues working normally.
Could a software update fix any of these symptoms instead of a screen replacement?
No — cracked glass, physical digitiser damage and panel faults are hardware issues that software cannot resolve. If you're unsure whether your issue is hardware or software (for example, a boot-loop with no visible damage), a force restart is worth trying first before assuming it's the screen.
