I have a Pixel 3 that has been fine, but its 64 GB internal storage frequently gets full, and I don't like needing to connect the device to my computer with a physical cable (it blows my mind that it's 2022 and I'm still using cables for file transfer) and move files to my PC just to free up space on my phone to keep is usable.
I see that there were versions of the phone that featured 128 GB of storage.
How could I buy a >=128 GB internal card (or whatever it's called) and install it in my device, replacing the 64 GB one?
