Hello to all and all, I'll explain how to do a "Screenshot" (screenshot) on your Sony Xperia X Compact. For this, nothing more effective than a small illustration.
Procedure: Press simultaneously the two buttons Volume Down + Power for a second. A message will then appear, confirming the capture.
You can find this capture in your notification bar, and initially it will be automatically saved in your gallery.
If you know other ways to do this, please share :)
