I bought the Acer Iconia B1 because of the performance (dual-core), the brand name and the reasonable price. The known weak screen and the toys housing I took into account. Great performance, dimensions and weight are fine. Super bargain! However, the front camera is a joke, there is no rear. The real disappointment came at the first use in the car: GPS without reception. After a 1/4 hour but then a signal, but with a deviation 40-80 meters! Even a larger tree led to the termination signal. Useless! Disillusionment number 2: Micro USB available, but neither connect a USB internet modems have an external keyboard possible. USB HOST function without! Disillusionment number 3: MicroSD slot available, but not suitable for swapping the apps (but seems to be an Android 4.1 issue, as well as the constant Werbeeinblendung "Recommended apps"). Disillusionment number 4: Then I wanted to test a game for my daughter just once: but "The Settlers HD" Seeing I only got white and gray blocks of pixels. Remedy would probably bring the APP Chainfire3D (as with my smartphone), it would have to but rooting the tablet. And that does not work with this device (yet). As already sobering number 5 offing (WLAN weaker reception than my phone), I gave it to an experience rich in good time on the 7th day (österr. Law) back. Things that should be understood in a new brand device, there are in fact not.
