Cheapest way to film yourself (uk)


What is the cheapest way of filming yourself? I do have a mobile phone, but it’s a very old Samsung Galaxy S7 and not suitable for recording.

I searched for cameras earlier on in the year and lots were out of stock due to chip shortages and whatnot.

Does anyone have any suggestions? Ideally I would not want to spend more than £200, and I know January sales are coming up :)
