GPS optimization, is actually essential?
Some android customers are experiencing GPS troubles ; are applications similar to this actually valuable and also secure for all tools?
What do you advise for a 2.2 tool?
It would certainly rely on the tool. Some tools have/had some actual significant concerns with their GPS. The Galaxy S is just one of them. It can take 10 secs for it to get a GPS lock or it can take a min (or perhaps extra).
If you never ever have any kind of concerns with your tool, after that I would not advise running an application similar to this. If you can get a GPS lock within a couple of secs approximately and also it is exact, after that I would certainly claim simply leave it alone.
