Acer hasn't messed around with Android interface and much of the features are left untouched. There are the usual custom widgets, theres a scrolling list of thumbnails that shows your Web bookmarks, and theres the 3 home screens.
The phone supports all of Android's usual fantastic features, including great Gmail support, the handy Google Maps and access to the Android Market, which is stuffed full of mostly free apps that further boosts the Liquid's prowess.
Acer's subtle additions to Android include the ability to merge your Facebook contacts with your address book. The Facebook integration is a good example of the Liquid as a whole; it does what it needs to, without making a fuss, and doesn't have too many bells and whistles. Acer hasn't meddled with the Android keyboard, so it very much works it was designed. The browser is also intact, so multi-touch zooming gets the boot, but its relatively fast and handles full webpages well.
The handset features motion and proximity sensors, the screen orients itself to landscape or portrait fairly intuitively. The proximity sensor will lock the screen when it is next to your face, and pops up new options when you pull it away, like engage speakerphone, put a call on hold or dial someone else for a conference call. Camera performance is typically good for a 5-megapixel camera phone. It can can also capture video at 640 x 480 pixel resolution maximum. It supports 3GP, MPEG4, H.263, H.264 formats, although you need to get the respective codecs. The Nemo Player comes pre-loaded and handles media well enough. Audio playback, once you plugin your own headphones to the 3.5mm jack is pretty good.
The Acer Liquid offers a slick, easy-to-use access to the Android Market so whenever you need a new application, you are just a click or two away. The handset is preloaded with DataViz Roadsync which enables Microsoft Exchange Server 2003 and 2007 support, as well as Documents To Go that lets you to edit and create Microsoft Word, Excel and PowerPoint files as well as view Adobe PDF files on the go.
It comes with assisted GPS for faster location times and Google Maps complete with Latitude, Street View, Traffic and POI search. The handset features one-touch access to YouTube & Picasa and supports social networking integrated address book, complete with real time notification of status or content updates.The Liquid offers a refreshing gulp of Android goodness, with some average Acer apps sprinkled in the midst. The Snapdragon processor is sufficiently speedy, and offers great connectivity and the big screen makes it an excellent web-surfing phone. The smooth, touch-sensitive buttons make for a great-looking handset that's up for grabs at a very accessible price. Overall the Liquid gets a lot of things right: the high-res and responsive screen, all the connectivity essentials HSDPA, GPS, Wi-Fi & Bluetooth and a speedy web browsing experience.
