UPDATE: Acer Liquid E3 and Liquid Z4 announced ahead of MWC 2014 with rear mounted AcerRAPID key.
Acer is trying to move up in the smart phone game and recently they have announced their Liquid S2 with specs that could finally hold a candle to mainstream smart phone makers. For the upcoming MWC 2014, they probably have something interesting to show as Acer has posted a teaser of their upcoming Liquid smart phone device.
There’s no further details of the phone except for a back shot of the device shown above. And what’s that thing at the back? Could it be a fingerprint scanner or a trackpad? or simply an action button for customised action. We’ll find out soon enough next week. Mobile World Congress 2014 is happening next Monday at Barcelona and it will be a week filled with smart phone announcements.
