Another thing to check. As you move around the house, probably more than with any other device, you could be passing through a dead area causing the wi-fi signal to drop out. To check this load an app called Wi-fi Analyzer by fastproc. You can then use it to wander around the house checking for weak signal areas and dead spots. Also, have you checked the advanced settings for your phone's wi-fi connection and set it to auto-connect?
Thanks for reaching out. I suggest sending an error report within 2-3 minutes of the issue occurring for this to be investigated by our research and development team.
