android - activity with viewpager and fragments does not resume the potrait layout when rotating the device. Only on Huawei smartphones

Introduction

I'am facing a strange problem that is happening only on the new device I am trying: Huawei P8.

I can't put a screenshot of what is happening but I will try to summarize as follow:

• The activity has only one layout in folder "layout"
• Some of the fragments that compose the viewpager have both "layout" and "layout-land" layouts for different views depending on the rotation of the device.

Problem

• Starting the activity in potrait everything works and the fragments have their potrait layout

• Rotating to landscape makes the fragments switch to their landscape layout (if the fragment has its custom landscape layout draws it) correctly

• When rotating back to potrait the problem appears. The fragments that have a specific landscape layout does not switch back to potrait layout keeping the landscape one and the result is:

  With the device in potrait the layout is drawn with landscape layout (took from layout-land) which is very bad to see because every view is compressed/stretched unnaturally.

I have tried many smartphones in the years and this only happens on Huawei P8 (android 5.0)
