The clear a obvious problem for this device is its terrible wifi. It shows poor signal, and disconnects itself from the network every few minutes.I was about to return it to Amazon, but gave a chance to a solution which actually worked around that problem.Here is what I did: I purchased an Edimax nano "7811UN-EW" USB wifi adapter, plugged it in, and disabled the original Qualcomm adapter.Bad for me to pay more, but better than wasting time on sending it back and ordering another device which probably has its own problems.
