2x regions with video looping problem - android

Hello!

I have one strange problem with video in region on android.

I have two regions, with the same video. On one device loop work perfect, but on another player loop don’t work. If I set just one region with one video the loop works fine.

Is it maybe possible android settings, or. client bug?

I have the same client version and the same android 5.1.1., but on different devices.

Ok, now I am tryed with one video and one picture instead the second video, and loop stop working, I am checking and if I add .jpg picture on different region, the loop don’t wokr, when I change picture with .jpeg format, loop works. The picture and the video are on different regions. On the second client all combinations works fine.
