FivePlayer is a free Android app developed by Yozii Co. Ltd. that allows users to stream videos directly through their browser. Upon launching the app, users can easily play sample videos. However, it is recommended to use Wi-Fi instead of mobile data as streaming videos over LTE or mobile networks may incur charges (with the option to exclude charges in settings).

When connecting to other devices via USB, note that there may be limitations, so it is best to use an AC adapter when charging is necessary. By default, the app is set to use H/W decoder. If the screen is black or there is no sound, try turning off the H/W decoder in settings.

For users who want to continue listening to audio even when switching to other apps, the app offers a "background audio playback" option in settings.

Overall, FivePlayer is a useful app for those who want to stream videos on their Android device. With its simple interface and customizable settings, it's a great choice for anyone looking for a free video playback app.
