Are newer android versions more resistant to 0-days than the previous

Are newer android versions more resistant to 0-days than the previous versions or it is the opposite because the version has not been tested long enough? I see that every new android version (eg. 15) introduces more security hardenings under the hood.

My phone still receives monthly security updates but it is still on android 13 and will not receive android 15. I wonder if it is worth it for security to spend some money on a newer device that will have android 15?

If your phone is still on Android 13 then you have some bigger problems like not even receiving firmware and driver updates.

I also bet that your phone doesn’t receive full security updates.

Wait what? My phone is still supported by the OEM. It is stock Motorola. It receives security updates every month. That should include firmware and driver updates. Why wouldn’t it receive full security updates?

Should i spend money to get an android 15 phone or to wait until support for my phone ends and save some cash?

Save up on a Pixel, ideally Pixel 8a or the upcoming Pixel 9a.

Thank you for the advice but that was not my question.

Wait until support for your phone ends so you can save up on a secure device like Google Pixel or an iPhone.

In general, yes. Do you know what the support period for security updates is for your phone?

I have about 1 year left after that i will switch anyway. It is though for phones in my area because degoogled phones like Grapheneos do not have very good support from the carrier and iPhones from what i see get more and more AI every year.

Pixel 8 or newer is generally a solid purchase. OS & Security updates promised for at least 7 years.

What’s the problem with that?

0-day has to do with either software or hardware, so quite unsure how can one definitely answer this question. Hardened security for android in newer versions do not necessarily mitigate 0-day vulnerabilities, well because it’s called 0-day vulnerabilities.

It’s always a better idea to keep your phone updated and patched as much as possible, so if you are looking for longer support, you’ll have to go to either iPhones or Pixels.

Because that is not good for privacy. AI analises my actions and builds a profile on me.

Source or FUD.

It depends on specific implementations. If it’s all local then it’s not all that bad.

What source do you want me to give you? This is well known already. I am not an expert i am not well knowledged but this is my understanding.

AI features on Android or iOS devices aren’t the same as ChatGPT and stuff.

That’s quite literally false, and seems like a fear-induced reasoning than informed reasoning. On-device processing of data has nothing to do with it building your profile. If you can point me to an article from Apple which says your interaction will be used to build a profile for you, I’ll believe your fear.

No, it’s not. Quite literally Apple’s “promotion” all these years has been that what you do on your iPhone is none of Apple’s business, including your interaction with Siri, or upcoming Apple Intelligence (I get a physical cringe saying this name).

What do you mean by this? If you get an unlocked phone all you really need to make sure is that it supports the bands your carrier uses.

I used Grapheneos in the past actually but my carrier did not support VOLTE and after numerous conversations with them and switching also to another carrier still the VOLTE function did not work. I also had some issues with missed calls, calls not coming through, mms not working, reception was worse than stock android. The carrier just said that Pixels were not intended for the market of my country and there is nothing they can do.
