Android phone will not turn on
Samsung's own warning matters here: on a fully drained battery the charging icon may not appear on screen at all, so a black screen while plugged in does not mean it is not charging. Do the Power and Volume Down hold for at least 7 seconds, then give it a proper hour.
Do these checks, in this order
Each one rules something out. Work down the list and stop when something changes, because that is your answer.
Do the force restart properly
Press and hold the Power or Side button and Volume Down at the same time for at least 7 seconds. Let go when the logo appears and the phone vibrates. A force restart does not erase anything. On a phone that looks completely dead this is the first thing to try, and it costs nothing.

Charge it for an hour on a charger you trust
Samsung warns that on a fully drained battery the charging icon may not appear on screen at all. A black screen while plugged in does not mean it is not charging. Leave it on a known good charger for an hour before you judge it. Use a different cable, a different plug and a different wall socket, because any of the three can be the fault.

Look in the charging port
Compacted pocket lint in the USB-C port is the most common cause of a phone that will not charge. Shine a torch into it. Grey fluff packed at the bottom is very often the entire fault.

Check for silent signs of life
Feel for a vibration when you force restart, and try ringing it from another phone. Plug it into a computer with a cable you know carries data. If the computer sees the phone at all, the board and your storage are alive and you are looking at a screen or battery fault.

Will not turn on on Android phone: questions
How do I force restart my Android phone?
Press and hold the Power or Side button and Volume Down at the same time for at least 7 seconds. Let go when the logo appears and the phone vibrates.
How long should I charge it before deciding it is dead?
Samsung warns that on a fully drained battery the charging icon may not appear on screen at all. A black screen while plugged in does not mean it is not charging. Leave it on a known good charger for an hour before you judge it.
Does a force restart delete anything?
No. A force restart is the equivalent of pulling the power and putting it back. It does not touch your photos, messages or files. That is exactly why it is the first thing to try and why it is safe to try.
Same fault, different device
The checks change with the device. If you are here for something else, start from the fault diagnoser or the Android phone guide.
