Player doesn't change quality of picture when it changes stream on SDMC device

Hi, I faced with very strange issues with adaptive stream on one of my device(And I want to call your attention that I can reproduce it only on one device(maybe it can happen on other devices but I don't have another device where I can reproduce this issue)).(link to devices, I don't remember exactly device name, will update it in monday) So, my app plays HLS streams and it change stream according to my current bandwidth, but I notice that on sdmc device quality doesn't change and it always plays stream with lowest bit-rate. So I logged HlsChunkSource to understand what happens.
When player start to play it start from the lowest bit-rate (here return index of a lowest stream). And I was very surprised when on next iteration getNextVariantIndex method calculate my bandwidth and return stream with one of the biggest bit-rate and player started working with this stream. But problem that I didn't see any change on screen, it still was picture with bad quality, but player worked with one of the best stream. So I decided to change this place to return here the best url index instead of one with lowest bit-rate, and I was very surprised when my player started working correct and now when it changes quality it changes picture quality too.

Same as #953. Please report the issue to the device manufacturer, since I do not believe this is an ExoPlayer issue.
