Factory reset and if the hardware is good it will return to its prior speed.

My phone is starting to get very slow and sometimes just gives blank page while I am searching.
It loses GPS signal all th time while on road trips now, in a large city, not just rural.
Can the phone just be to old to work perfectly anymore?
Phone calls are not being dropped, that portion is ok it is more the smartphone apps that are just dragging.
Any thoughts?
