How do I prepare my Android for Exchange/sale?

[TallTrees]

I have been looking at the Samsung A50 or A70

I would most appreciate advice on how best to

clean my phone which is  an Android Lumia 640 ready to hand in for exchange to Samsung.

I have removed all photos.

I have removed all contacts

I have removed all my email accounts

Any other advice would be most welcome too.

I think that the sim I have is larger than required for the Samsung phone

Maybe O2 shop could assist there?

There is an O2 Shop and a Samsung Store near to each other in Town.

Thanking you TallTrees

There is a reset option in settings which will wipe your phone of anything and everything and if you need a smaller SIM card, the shop will do that transfer while you wait

Settings/ search "reset"
Select "factory reset"

Most obliged and thank you @Bambino 

will read through that thoroughly.

That sounds perfect ~ I was hoping the shop could get the phone up and running quickly for me.

Thank you very much @MI5

Thank you very much for the reset info. I will do that ~

@viridis kindest thanks 

[TallTrees]

Should I do all these actions with my sim in the phone?

It doesn’t matter if the sim is in or out and obviously you won’t be able to use the phone once reset anyway.

ok ~ so all this work needs to be carried out just before I pop down and exchange it. 

I take out my sim and my sd card (which is extra) and hand it over to Samsung.

Thanks for the info ~ not obvious to me as not done before @MI5
