Galaxy A31 Screen Repair · Same-Day · North Providence RI

About this repair

The A31's 6.4-inch FHD+ Super AMOLED is fused to its cover glass, so a cracked front means replacing the laminated panel rather than swapping glass alone. Its optical fingerprint reader sits directly beneath that OLED, so on this MediaTek Helio P65 model we recalibrate the in-display sensor after every screen replacement to keep unlock working. We also renew the glued 5000mAh battery, which tends to swell with age and bow the rear cover, and rebuild the USB-C port when its 15W charging turns intermittent.

• OEM Super AMOLED Assembly with Frame (Service Pack)

Will my in-display fingerprint still work after a Galaxy A31 screen replacement?

Yes — the A31's optical fingerprint sensor reads through the Super AMOLED, so we recalibrate it after fitting the new panel; lower-grade non-OLED parts can break that reader, which is why we match the original Super AMOLED type.

Can you replace just the glass on my A31, or do I need the whole screen?

Because the A31's Super AMOLED is laminated directly onto the cover glass with no separate touch layer, glass-only repair risks the panel, so we fit the complete display assembly to keep the FHD+ resolution and touch perfect.

The back of my A31 feels puffy and the battery drains fast — can you fix it?

That is the glued 5000mAh cell swelling, a common A31 fault after a couple of years; we safely remove the expanded battery before it cracks the panel, fit a fresh one, and reseal the back so it sits flat again.
