Mine was part of a batch with Qualcomm modems that had actually failed QA. The modem used to freeze randomly. Various devs (not Pinephone staff) came up with a series of increasingly effective workarounds. But the thermal issues are the real killer.

Pinephone does hilarious things to shave a few cents per unit, and the rusted-on fans gaslight complainers by asking if we really want an open hardware phone or not? I do, but it needs to do what the advertising says it does...
