My phone came with a11 and is now on 13. I would have loved to stay on 11. Every update seems to take more things away than add any features I would actually use. An example is a12 making it so certain links can only be opened by default by “trusted” apps, Youtube for one. I’ve found workarounds but it’s still annoying.

I bought headphones with aptxLL, only to find out that newer Qualcomm chipsets have depricared it in favor of aptx adaptive. It’s not backward compatible and at the time there wasn’t a single adaptive set of headphones on the market. I would either have to buy a >4 year old phone or get a new pair of overpriced headphones to use it now.
