Cheap phone with longest update support

I am being forced to change my phone since my organization's BYOD policy has stoped support for OS less than Android 11.

I am using a Vivo from 2019 with SD675 4GB ram and it has worked flawlessly.

I need a cheap phone which will provide the longest updates atleast till 2027 end

I have shortlisted the Samsung Galaxy M35 since it has Exynos 1380 which has 4 big and 4 small cores enough for daily performance and also heard they provide long updates.

Please pour your suggestions. Country: India
