After I recently updated my phone about a day ago, this strange sign showed up on the top left that I have never seen before. Does anyone know what it means? Or how to get rid of it?
If this is the icon you are looking for then it's the Data Saver icon in Mobile /Network Data option:

Status bar icon is to show that
Data Saver is ON. Data Saver controls data usage of device .
To turnoff Data saver, go to Settings-> Data usage -> Data Saver and turnoff. There you can see an option named
unrestricted data access, which you can set application that can use data, even if data saver is ON (Eg. Google Play Services ).
Ok, I found out. It's the "reached the data cap limit" icon. Note that it's not found anywhere.
The icon is visible here, near "Data usage". The same icon will appear in the top notification bar:

The icon disappears
