I was looking for a cheap phone with Andoid 4.xx and since the technical specifications of the Liquid Z3 (or Z130) sounded good (dual SIM Kannes also, for me was not important), my choice fell on this smartphone , In many reviews the display resolution is criticized what did not bother me in the size of the display, but the Acer's own interpretation of the operating system, or the Android interface verschlimmbessert lot and can not top manufacturers such as Samsung or Sony, the water rich. Particularly disturbing is the poor recognition of finger position - often I could not move to where I wanted them, sometimes they were not at all move the icons. After about 2 hours agonizing configuration tests the Z3 therefore went back. As a substitute, I have now decided for the Samsung S3 Galaxy Mini - ok - that's twice as expensive, but what a blessing in setting up and operation - Affordable alone also makes just not happy.
