So my Google Nexus 4 that I bought years ago from a deal on here has started randomly dying all the time. It used to shut down occasionally, but now it does it really often. When it does it makes a weird noise almost like when old hard drives used to die. When I turn it on again it optimizes apps before it boots again which takes more than 30 mins. I've noticed that my phone signal disappears along with wifi often before it crashes. Also using Youtube can kill it.
I'd like to keep using it if I can, but it's probably time to let it die.
So if I have to replace it can I have some recommendations on a new phone please, as I know nothing about them.
My requirements is to be an Android phone, have expandable memory, as the Nexus pissed me off not utilising SD cards. Also a good camera would be nice. And also be fast. Extra points if it's waterproof, but that's probably pushing it in this price range.
I look forward to everyone's input!
lg g6 is in that range, and meets all your criteria
