official screen replacement source?

Hi @mitchlevine

A quick search online for a OnePlus Nord CE 2 5G (IV2201) Display module front cover + LCD + digitizer found this supplier

It states the price and also says "original".

There were others and their prices also didn't seem as high as the one you were quoted. I assuming you just meant the part itself and not the cost of a full repair done by them? Didn't check any others but noticed some said TFT screen and not Amoled screen which your model has so I assume that they're not OEM but maybe compatible only

There are different options for screens, oled, lcd, with frame, without frame. I agree 250 is very high so I'd suggest trying a different repair shop. It is possible to do it yourself if you buy a screen with the frame attached. You'd need to buy some adhesive too to close the phone afterwards. There are loads of screens on ebay (uk anyway) so loads of choice. Always check the sellers feedback as there are some bad ones on ebay.
