Replacement screen not working

I replaced my Pixel 3a screen and the new screen is glitchy:

The ambient display shows at full brightness and when transitioning from ambient display to lock screen, the screen flashes white at full brightness.
The keyboard requires significantly more pressure than on previous screen. Therefore, when typing quickly, many keys are wrong or missed.

When I disable the ambient display, the flashing goes away — I can press the lock button and the lock screen appears without issue.

How can I diagnose the cause? The previous screen was cracked, but otherwise fine, so I assume it is the new screen. But, is it possible that something else is causing the problem? I followed the directions on iFixit and encountered no problems.

Sounds like a defective screen or it’s not seated properly. If you cheaped out and bought one from eBay, Amazon, Craigslist, Wish, or AliExpress, that’s why. They don’t specialize in screens and anyone can sell junk parts for dirt cheap.

Thanks. Understood — I bought it from iFixit (and paid the premium) exactly because I was afraid of a bad part. Any thoughts on how to distinguish a bad screen from a bad seating? Do these specific symptoms make sense for a bad seating? It’s not flaky — it’s very reliable in its problematic behavior.

@ymandelb good I'm glad you bought from a reputable source. The only way to distinguish between a bad display and improper seating is to disconnect and reconnect the display. Inspect the connectors and cables while you're at it. If it's still acting up, it's most likely a defective display.

I reseated it and checked the cable and connector. Everything looked in order, yet the reseating had no effect. I'll try to get a replacement from iFixit and see if that does the trick.

Here's ifixit's returns policy (there's a contact us link towards the bottom of the page).

Perhaps you should temporarily reconnect the old screen (presumably still working just cracked) to verify that the new screen is the problem just in case something else happened during the repair
