The phone is also impressive when it comes to connectivity. Naturally, it’s quad-band and supports HSDPA at speeds of up to 7.2Mbps. There’s also Bluetooth 2.0 + EDR as well as Wi-Fi and the onboard GPS worked a treat with the Google Maps application, as it was quick to get a lock on our position even from a cold start.
The 5.0-megapixel camera isn’t so hot though. It does have autofocus, but lacks a flash so low-light shots are a bit of a no-no. However, if there’s enough light in a room or it's working outdoors the results aren’t too bad as colours look reasonably accurate and it does capture a decent amount of detail.
Audio quality from the supplied headphone isn’t too bad either, but we’d still advise you to swap them for a better set of cans. That way you’ll get to appreciate the handset's impressive audio performance. However, if you're planning on loading the phone up with lots of tunes it's rather annoying to find that the microSD card is very fiddly to get at. It’s hidden under the battery cover, but worse still you have to actually take the battery out to be able to slide it into the slightly recessed slot.
The Liquid A1 doesn’t have the fancy 'Sense' add-ons that are offered on the Hero, but then unlike Windows Mobile, we’ve never been that convinced that you really need them on Android in the first place. Plus the phone certainly feels a lot more sprightly to use than the Hero as it doesn’t suffer from the slight sluggishness that can creep in to that model. It’s just a shame, then, that Acer hasn’t added multi-touch and improved the build quality a bit. If it had, Acer would have a real corker on its hands. As it is though, this is still a very impressive Android handset.
