Con Android permission location
Today, most browser developers put 2 location permissions: 1) Precise & 2) Approximate, most people search goods & services "by typing name of specific region or place".
i.e: books library in "name of city"
So, is there any need to such permissions which is a privacy concern ?

In extreme data saving mode, it sometimes won't load page correctly.
