With lineage os getting updates, it’s the hardware device drivers that are at risk… I can’t tell you how unsecure they are, I can just tell you no product ever created is perfectly secure, and with more time exploits are found. This applies to phones as well. Not to mention the chip manufacturers tend to use the same cores on multiple devices. So there’s many researchers looking at those different cores to find exploit

I can’t use Lineage on my V20 since it doesn’t work with the proprietary drivers for the only antenna on the thing that Verizon still supports.
