Yeah I used to have one, I only replaced it when the battery started going. I loved that phone, it was solid yet so light! I have a 6a now which is great but so much heavier than the 4a.

Yeah they’re not doing it for 4a, Google might offer you a voucher to replace your phone.

But this is just for the 9a, the 9 has the superior chip. The “a” models have always been smaller and lower spec, and therefore cheaper.
