Since I had some time looking for a dual SIM mobile phone with Android, which is here as one of the first mobile phones a well-known manufacturer. First of all I have to say that the battery is really neat. In normal use, incl. GPS navigation I had a good 42 hours service time to it "finally" ran out. Now the phone itself - it is going really well. All Apps launch liquid and also the configuration is not a problem. BUT: You should use the app at instalierte SMS and install any extra for example. The software not figured that they should send the SMS with the second card and sends so cheerfully always from the primary SIM. Other pitfalls I have not found. So far I am satisfied and would recommend if someone is looking for a dual sim.
