Galaxy A40 Screen Repair — Same-Day, North Providence RI

About this repair

The Galaxy A40 packs a compact 5.9-inch FHD+ Super AMOLED fused to its front glass, so we replace the whole assembly to restore touch and the Infinity-U notch display cleanly. Its small 3100 mAh battery is glued in and a frequent wear point on this 2019 model, so we re-cell with fresh adhesive while checking the USB-C port. The A40's fingerprint scanner is rear-mounted on the back housing, and we verify it still reads after any back-cover work.

• Aftermarket Soft OLED with Frame
• Premium OLED Assembly

Is the Galaxy A40's fingerprint sensor on the screen?

No — the A40 uses a rear-mounted capacitive fingerprint scanner on the back housing, so a front screen replacement doesn't disturb it; we only re-test it if the back panel is opened.

My A40 battery drains fast — can you replace it?

Yes, the A40's small 3100 mAh battery is a common wear point given the phone's age, and we swap it with fresh adhesive and confirm healthy charging through the USB-C port.

Do you replace the whole screen or just the glass on an A40?

Because the A40's 5.9-inch Super AMOLED is fused to the glass, we replace the complete display assembly rather than only the outer glass, keeping touch and Infinity-U alignment correct.
