Should you happen to bust your brand new Pixel 4a (review here), note that Google recommends you take it to a uBreakiFix location. This announcement follows a history of the company recommending buyers take their Pixel devices to this repairer.
As uBreakiFix notes, “Each uBreakiFix store is equipped with Google-trained technicians to provide authorized repair service for cracked screens and other technical issues using genuine OEM parts.”
It should also be noted that uBreakiFix offers authorized in- and out-of-warranty repairs for the Pixel 3a lineup, as well as out-of-warranty repairs for Pixel, Pixel 2 and Pixel 3 series devices. Basically, if you have a busted Pixel phone, this is the spot to go.
Peeking at pricing, a screen replacement for the Pixel 4a will run you an estimated $140. My suggestion is, try not to break your brand new phone.
