In India that is the story with Motorola phones. They have started making decent hardware, as in competing with others, but they sometimes don't even respect updates for their flagship phones. And then, they are not alone in this.
I took an Android detour late last year, early this year, just to see what the other side looks like. From the major vendors, only Google releases security updates like clockwork across all devices (similar to Apple).
Many Samsung flagships have monthly updates (good), but rolling out the updates is a shit show. Like the S23 could get the update on the 11th of a month (~10 days after Google opened the monthly security bulletin), while the S22 would only get updated on something like the 28th. Also they usually missed Google's 5th of the month platform updates, causing some flagships to be vulnerable for a Bluetooth RCE for almost two months.
Then some security updates are rolled out through the Google Play System updates (not Google Play or Google Play Services), however, the rollout regularly gets stuck on non-Google devices until someone at Google (?) fixes it. For instance when the Samsung S24 got out early this year, phones were stuck on the (I believe) July 2023 Play System.
If you want regular updates on Android, your best bet is getting a Google Pixel. Unfortunately, Pixel has a long history of issues (like not being able to call emergency services).
