You can use this cool trick to watch movies on TV directly from your Android smartphone wirelessly.
This is a very easy and straightforward process, just follow the steps below:

1. Go to settings or swipe down the notifications tab.

2. Search for “Cast” or “Screen mirror”. It’s called cast in some devices while in others it’s called screen mirror (keep this in mind). Whichever
name yours is called, just select it and wait for it to search for your TV or streaming device.

3. When you see the name of your smart TV/streaming device among the search options, select it. Wait for it to connect. If the search is not
bringing up any results and you’re sure that your smart TV/streaming device is turned on, check the cast/screen mirror settings. Enable wireless connection if it wasn’t enabled before. You should see your smart TV/streaming device after this step. Select it and wait till it connects.
