I've used a xiaomi redmi note 4 (mediakek) for many years before i got it stolen. I've purchased a xiaomi redmi note 10 after that (i am supposing there were six years in between). I was still using it but then I needed one of these big folding phones and bought a samsung z fold 5. It broke down in 2 years, i am back to my redmi note 10. Still going strong. I will never buy an expensive phone again it was a dumb move. Just the cheapest android on aliexpress.

My Huawei was still absolutely fine for me speed-wise. I moved to a Xiaomi 14 for a little while which was obviously faster but not in a "holy shit it's fast" sort of way.

The Pixel is slower than the Xiaomi in benchmarks but I can barely tell any difference in day to day usage.

Maybe if I went back to the Huawei it would feel slow but honestly I would still be using it if it had been updated. Unless the new OS slowed it down.

unlock the bootloader and flash Lineage OS.
