Pixel 4a here. Been running fine for the most part. I do want to upgrade eventually because I like newer shiny tech but what's holding me back is losing the fingerprint reader on the back. My wife has a 6a and loves it (I do too) but the hassle of the fingerprint reader is just so off-putting. I've seen the same concerns with a couple other devices with the in screen reader, so we'll see. Might upgrade to the 7a in the future when it's on sale or something.
Yeah, 7a on sale is worth it. Got the 7, was €30 cheaper with Cashback when the 7a launched. So was easy choice for the 7. Loving it so far. Came from Xiaomi. Also good, if you block their data hoarding.
