In November 2020, when I bought my Google Pixel 4a 5G, I also bought a Spigen Ultra Hybrid Case (#ad) for it. Sometimes I use it. Last Monday, a time that I didn’t use it, the phone fell out of my back pocket onto concrete, landing on its lower left corner and cracking the screen.
After finding out that I hadn’t purchased device coverage for the phone, I bought a replacement display (#ad) from Amazon for $169.44. From the various choices of Pixel 4a 5G replacement displays on Amazon, I chose the (difficult for me to pronounce) YWLRONG replacement display because it also came with a great set of tools: double side adhesive, an anti-static spudger, precision tweezers, six different screwdrivers, a guitar pick, SIM card ejection tool, suction cup, stainless steel pry tool and B7000 adhesive. I really only had to use the suction cup, stainless steel pry tool and a hairdryer to heat up the adhesive to remove the display. After cleaning the old glue from the case, I used B7000 adhesive to install the new display. It was very straightforward.
I usually turn to iFixit for great instructions on fixing stuff and there was a nice writeup, Google Pixel 4a 5G Screen Replacement, by: Sam Omiotek (and 2 other contributors). This Google Pixel 4A 5G Screen Replacement YouTube video was the most helpful of the several I viewed.
