Second purchase of a refurbished smartphone, and it's the same satisfaction: on the one hand you can afford a higher range than a new product, but on top of that you're doing the planet a favour by avoiding the pollution of new production. However, I'd recommend doing your homework on the test sites beforehand, so that you can match the offer on BackMarket with the capacities you want on the test sites.
In this respect, the Edge 20 lite is a very good choice: the photo function is superior to the norm, the battery lasts even on occasion (provided you adjust the screen settings properly, in particular), it has an SD card slot and a jack, and above all it runs up to Android 13 (which means it's Android Auto compatible - my old Galaxy A5-2016 was in 6.0 and so didn't work with it!) The screen is also very good. There are a few minor criticisms, however, including the lack of any option to deactivate fast charging (which puts more strain on the battery than slow charging), the phone's size, which is starting to get large, and the aggressiveness of the pre-installed apps. What's more, the phone's previous owner had clearly never heard of screen protectors. XD
But honestly, a refurbished Edge 20 lite is excellent value for money right now (2025). =)
