Our tester failed to upload video file(.mp4) on specific android mobile phone, but he could upload same file on iPhone and another android mobile phone.

Then I tried to test with him by connecting the android mobile phone to PC by USB to debug on chrome developer tools. But I couldn’t find any errors so far.

And I tried this changing php.ini like below URL:
xmlhttprequest file upload not working on mobile
It was not work for me.

Does anyone have some idea to solve this situation?

Thanks in advance.
