My SiteHawk SK-4500 shows "connecting" and will not get past this screen.

Sometimes there is a file that gets corrupted so one thing to try is to Uninstall the SiteHawk app, delete the SiteHawk folder and all of its contents, then re-install the SiteHawk app.  If you have saved files or screenshots you don't want to lose, then it is recommended to offload them to a memory stick for later use. 

If the .apk file is not on your SiteHawk, it will be on the memory stick that came with the unit.

See attachment for step by step instructions to follow.
