!!! DON’T DO THIS !!!
If your battery is that bloated, that you cannot close the cover: Immediately STOP to use your Fairphone and remove battery and store it at a safe place!!
Don’t foget this for writing to the support:
Contact our Support Team with the subject line “Bloated battery” and we will make your issue a priority.
I am sure, that they have battery for warranty reasons and sending to you for free!
In which country your are currently?
Best wishes although you have to give your FP a pause!
Cheers, Robert
