we have published live app with vuforia 2 and cloud recognision. It wokrs pretty well on all of our devices apart from Sony Erricson ST25i
On this device we are constantly getting time sychronization error. This is regular model one week old with very little customizations if any. By default the time was set to be set automatically provided by the network and it was set correctly. We also tried to manualy fiddle with the time settings but nothing helped.
In the log cat there is nothing interesting, just logged AR cloud transaction ID. here is one of them so maybe you can check the request at your side?
01-03 10:45:03.203: I/AR(3163): Completed CloudReco transaction with ID 'f8ae9fc4b37d44178bdc592638afcac0'
