The Acer Liquid Z630 is a smartphone running Android 5.1 Lollipop out of the box. Even though it’s listed as a smartphone, it’s the size of a phablet, with a 5.5-inch display. The Z630 was announced and released during September of 2015. Smartphones are getting larger as time goes by, but many are finding anything above the early 5.0 inch mark is too large for a phone. The Liquid Z630 is a great buy if you don’t mind the size.
