So when Google issues a kernel patch for an actively exploited zero day you aren't vulnerable?
Don't be ridiculous.
Software zero days can be patched and on Android even the vendors with the best support policies only cover half as many years.
Cheap Android phones don't even get that.
The OG iPhone SE is on it's sixth year of OS updates.
The iPhone 5s just got it's eighth year of security updates.
Even if it's a software flaw that can easily be patched, but the vendor prefers to force you to buy another device and toss the first into a landfill.
$250 is about the max I would consider spending on a smartphone.
It’s not as flexible but my end cost for the phones is usually $5 more a month in plan cost and being stuck to a big 3 carrier, I haven’t paid much for a phone since I started doing this after Att paid T-Mobile equivalent of $4B in break up fees a decade ago and that pushed for more competition. Though back then I was rocking webOS then Windows Phone before sadly going from iPhone to iPhone. I believe it was iPhone 6 to 8 to 13 Pro. So 3 year and 4 year gaps waiting for deals where I wouldn’t pay anything except a trade in and being tied to the carrier.
I also use a ton of data. Except during the first 1.5 years of the pandemic. During that time period I for sure was wasting money.
I would rather have a 10/month phone bill than a 40-50 one.
