I upgraded from gingerbread to ice cream sandwich on my Galaxy S2 and since then I have had problems pin pointing my location which impacts on the navigation systems. Some.times a location can be identified but most of the time the app searches for a GPS location and will remain like this until the app is stopped. I have downloaded other navigation software but they all struggle to find a GPS location. Before the upgrade the app worked fine. The phone is standard from the network and is not rooted. I have installed a GPS fix software that does work and a GPS location is found but, when I press the home button the GPS fix software is shut down and GPS reverts to struggling to find a location. I have reinstalled ICS and the problem remains the same. Deleted the apps and no change and also deleted the app updates and nothing improves. I do not mind reverting back to gingerbread but would rather find a fix to the problem. Any ideas?
