Brand new Wiko Lenny 2 since yesterday

[goalsurfer]

Can somebody inform me how to insert the battery?  I inspected the box, browsed through the smaller manual and searched a manual on the Internet.

I find that the topic is skipped everywhere.  It was packed with the battery outside the phone.  There are some things that are maybe locks but I dare not force it.

Nothing unusual, really. Maybe just a bit more difficult than average.
