Overview
What this Xiaomi Redmi 12 flex cable is
If your Xiaomi Redmi 12 has a worn or damaged main mother board LCD flex, swapping in a brand new OEM standard part is usually far cheaper than replacing the whole phone. Swapping the flex cable is a focused repair that tackles connection faults between the main board and the display. Choose this listing if your search was "redmi 12 lcd flex cable", "xiaomi redmi 12 main flex" or "redmi 12 display flex cable". It ships from Manchester by Supreme Phone Parts Ltd, a Top Rated eBay seller, and every part is tested before it goes out, as "redmi 12 lcd flex cable uk" shoppers will want.
This main mother board LCD flex for the Xiaomi Redmi 12 suits faults such as a blank screen with the phone still vibrating or ringing, display lines, flicker and unreliable touch. Check the screen itself first, then fit the flex if the connection is at fault. It is a focused repair that leaves the rest of the phone untouched.
The Xiaomi Redmi 12 flex cable price here is £21.99, with free Royal Mail Tracked delivery on UK orders from £5, for a new part made to OEM standard.

Item arrived promptly which is always the case with this seller. And as usual well packaged. Sadly the postal service mishandled it and may have caused the failur eof the unit. Seller made instant refund. Decent communications too when i am sure they have a ton of orders to juggle. I have no issue recommending them and have now had half a dozen digitisers and all te others worked so far.
