Meh, if Android 7 has so many bugs, the later versions must have even more bugs. I'm not sure quite what I'm supposed to be at risk of. I don't run any Google Play apps, have mobile data turned off most of the time, don't have much really private info on the phone though I do have some auth credentials there (TOTP app that uses some kind of hardware secret store, plus API key for email app). If I had to replace my phone right away it would probably be with another Android phone, but in the long run maybe I'd prefer a Raspberry Pi tablet or something like that, plus a separate voice-only phone or wifi hotspot. Unfortunately VOIP seems to suck badly, at least with the app I've tried (Linphone). And also unfortunately, 2G is dead so I can't cobble together a DIY dumbphone using an ebay module. I don't think they have those for 4G yet.

If you have any particular suggestions of a phone that is 1) cheap, 2) has a headphone jack, 3) has easy to replace battery (having to open the phone with a screwdriver is acceptable, but having to melt adhesives with a high chance of destroying the phone is not). A built-in e-compass for navigation would be nice to have, and a decent camera (the 5MP one that I have now is ok, but the one in the N900 was awful). I don't need any high end features that I can think of. Lowish res screen is fine but it should be large. Wireless charging would be nice but that seems to conflict with easily replaceable battery. I am thinking of the Moto G Power which has some older versions on sale at Best Buy. But again, I'd rather postpone a new phone as long as I can.
