I visited 3 stores looking for the pixels 7a. One of these stores (best buy) sells it at a 20% discount for only 2 weeks, brand new, 128 GB, so I may go for it to buy and nuke to install graphene OS, then relock it.
A poster suggested me to avoid verizon, because they lock the bootloader to prevent you installing anything else.
This one seems to be a pixels directly from google: on a table displaying other google devices and earbuds, but I wouldn’t want to buy something I cannot relock on non-stock software.
ETA: what port does it use for charging?
More secure: any bootloader tampering happening via physical access to the device will trip the warning.
More compatible: some apps (banks usually) flag an unlocked bootloader as a security threat.
Thanks for answering!
