I'm having problems with my S5 since upgrading to firmware to 3.5.7_002008. It has not completed a clean since the upgrade. It gets lost. it gets parts of the maps rotated. Before the upgrade it would complete a whole house clean 90% of the time. It is a big house and needs to return to the dock for a recharge to do a full clean.
Is there any way to roll back to the previous version of firmware? The new has lots of nice features but they are useless if the basic navigation does not work.
