If you want to stick with Google, then 5a or 6 / 6XL will be logical options.
But based on rumors, these phones will most likely not be sold in SG officially.
No big deal if you don't about local warranty.
Been using the Pixel 4a raw, pretty good.
Plastic back, wont smudge with finger prints.
Pixel 6 definately is a S$1K++ phone, will only have enough for a Pixel 5a most probably.
As long as Pixel 5a is not anyway bigger then Pixel 4a i might give it a try.
Else i might need to find ways to repair my Pixel 4a screen :/
