Some users have reported "time travel" or general instability issues when the DRAM inside the PinePhone is configured to run at a higher frequency. I would suggest that you try lowering the DRAM frequency and see if the issues go away.
Manjaro ARM builds and packages a few variants of U-Boot for the PinePhone, which allow different DRAM frequencies (492, 528, 552, 592 and 624 MHz) to be easily tried out. Just write the desired variant of the U-Boot to your boot device, reboot and test.
