Literally typing this on my just arrived A2 lite.
It's replacing a nexus 6p with the much maligned "software update buggers battery" fault followed by battery replacement eventually causing a unrecoverable bootloop.
First impressions: slightly smaller, but better to hold. shame about the notch. Feels nippier.
Cost me £121 compared to the nexus 6p's £350 when new. I don't see anything in the mid to high end market that's worth paying several hundred pounds more for.
NFC? Can count on one hand the number of times I used it on the 6P. It's got a finger print sensor and an SD card slot. IP68? Nice to have but not worth the cost.
