Some people are faced with problems probably caused by baseband.
Problems reveal as:
- poor coverage
- unstable mobile data transmission
- poor GPS performance (slow fix)
Occurrence of mentioned problems also depends on the network. If everything works fine, there's no need to change your baseband.
Updating your baseband to the latest version can be a solution but sometimes the older version works better in specific network. You have to check it yourself.
