My personal security metric is "how many bitcoins would I leave in a wallet app on this phone". Currently that number is about 1 ($30k) on an up to date android. I believe that if I had more bitcoins on a phone, and told people about it, there's a good chance a targeted exploit would steal those keys. Even if I had them encrypted, at some point I have to type a password in to decrypt, and that would be the point they…
Well yes, I would consider any Android device family other than the Pixel / Nokia line a security hazard, with or without any bitcoins on it. Comparing a rushed Q4 market Samsung phone to an iPhone is simply comparing a brick and an orange. There are many problems with Android, but that the price for a zero day exploit on Android has become more valuable than one for iOS as far as 2019 [0] should tell you something a…
As someone who uses a HMD (Nokia) phone, please do not buy the models with Mediatek SoC in it when you are absolutely concerned with security. Apparently Mediatek is the one building the kernel of the device and not even HMD has knowledge on what modifications have been made (for example is DuraSpeed, which was an aggressive battery saver that ruined some apps, was enabled without permission and even HMD cannot disable it permanently). Qualcomm SoC devices are okay, but expect a slight delay (around a week or two especially if it was a device from a carrier) for updates.
