Hi Zsolt, thank you for your input, Yes I'm very well aware of that issue thus I already set a time comparison module between server time and first boot timestamp on the server end. The registration process will take whichever time is lesser. Therefore, assuming no body bypassing the system, the warranty will be started with the timestamp of the first time boot up (which is actually lesser than the time of synchronization with server). In addition on the device end I put some security measure on the timestamp record. This issue is already agreed upon consensus of our team.
However my question is how to deploy an app that will run exactly after the setting up account process and will not run again if the system is rebooted?
