Overview
What this part is
Inside the Samsung Galaxy A30 a long flex cable joins the main board at the top to the charging board at the bottom, and a flex also carries the display connection. If one of these is torn during a repair, bent or corroded, the phone can stop charging, lose the screen picture or lose touch, even when the screen and port are fine.
This part supplies the main board flex cable together with the display flex. Compare the connectors and length with your old parts and the photos before fitting.

How to check your model
Open Settings › About phone. The model name should read Galaxy A30 and the model number should start SM-A305, not Galaxy A30s. Samsung model numbers start SM-.
The Galaxy A30 (SM-A305F) and Galaxy A30s (SM-A307F) are different phones with different internal parts.
Professional installation
How a technician fits this part
- Power the phone off and remove the SIM tray.
- Warm the back cover edges gently and lift the back cover off with a thin pick.
- Remove the screws and inner cover, then disconnect the battery before anything else.
- Unplug the old flex cables from both boards and peel them away carefully.
- Fit the new flex cables in the same path, press each connector home and reconnect the battery.
- Test charging, display and touch, then refit the covers and back cover with new adhesive.
Check that the part matches the device before fitting it or removing any adhesive backing. Once a part has been fitted, it cannot be returned for a change of mind. Faulty parts are always covered.
FAQ
Frequently asked questions
Will this fit my Galaxy A30?
Yes, if Settings › About phone shows Galaxy A30 (model SM-A305F). It is not listed for the Galaxy A30s or Galaxy A50.
Does it fit the Galaxy A30s?
No. The Galaxy A30 (SM-A305F) and Galaxy A30s (SM-A307F) are different phones with different internal parts. Check Settings › About phone before you order.
Which flex cables are included?
Two: the main board flex that links the top and bottom boards, and the display flex. Compare them with the photos and your old parts.
Is it made by Samsung?
No. It is a brand new, OEM-quality part made to fit the Samsung Galaxy A30, and it is tested before dispatch.
Should I fit it myself?
We recommend professional installation. The Galaxy A30 has to be opened with heat and a pick, the battery must be disconnected safely, and the flex cables are thin and easy to tear.
