Phone recommendations around £150

Hi everyone 👋 I'm looking for phone recommendations for my son, he would be grateful enough for a cheap and cheerful but I'm wanting to spend a bit more and get him something to hopefully last. He loved his P20 Pro which makes things more difficult because there is nothing around the same spec and price that I know off. Camera quality isn't massively important however if storage is low it must have the option to add a memory card. Hoping for something that will have updates for a while too. I currently have Samsung A53 and love it, would have expected the price to have dropped enough to get him one too but it's actually more than I paid 6 months ago haha. Thank you in advance for any advice
