Did you already read and understand https://wiki.pine64.org/wiki/PinePhone#Introduction ?
Are you really aware what to actually expect when purchasing a Pinephone?
You can't have a device featuring a deceptively false sense of security that can't be "tampered with" and at the same time be able to do what you please with it.
The whole point for the existence of the Pinephone and related offerings is the possibility to "tamper with" the firmware.
This is a device destined for modifying its firmware as you wish (and are capable to), aimed in first place at *developers*.
This is not a consumer device and not suitable to deliver some kind of "smartphone experience" for end users.
So, unless the seller hasn't bothered trying out firmware installations, this will definitely have been played around with.
If you are worrying about malware and security, then this is the wrong phone and you are not a member of its target group.
If you don't trust the buyer and don't know what the Pinephone stands for then better abstain from purchasing it.
