Will a firmware update erase my personal data? A friend of mine has a Samsung Galaxy S5.
It is actually prompting to update the firmware. But the updatetext (its actually in german) reads ambiguous. Translated it says something along the lines

Initalize the latest Version.
All configurations will be initialized and saved data will be erased.

The problem with the german text is it isn't distingtive this means just the Configurations data or ALL data. I wasn't able to find someone having this problem by googling (I'll just get spammed how to delete/erase the updateprompting...)
SO I'm asking here:
What kind of data is meant to be erased for a Samsung Galaxy S5 when performing the latest firmware update? (If it matters, current version: PDA:OJ1 / CSC:OJ1 / PHONE:OJ3(XEF))
Do a backup of your phone's important files, don't risk it, if the phone reinitialises it isually resets it to its factory version, erasing all the data. Also your apps are very likely saved in a list so that you can reinstall them after the reset, so don't worry about them. Use google drlive or some other service, take the SD card out, and do the firmware update, if you want. Just don't risk it.
