Samsung has now made the Galaxy S4 mini smartphone official and it will replace the Galaxy S3 mini.
With the Galaxy S3 mini still firmly on the market and being pushed by many of the UK's networks, you're probably wondering whether to opt for the new or old. We'll highlight the differences for you section by section to help you work out which is the right smartphone.
Samsung Galaxy S3 mini vs Galaxy S4 mini: Price
The Galaxy S3 mini, now it's been on the market a good length of time, sells for around £230 inc VAT on a SIM-free basis. This makes it a pretty cheap phone, ignoring the fact the Nexus 4 is only £9 more.
There's no price for the Galaxy S4 mini as yet so we can't make a proper comparison here. We do expect it to cost more though. After all it's a newer model with a more up-to-date specification.
A price of around £350 is our guess, but we'll update this once we know for sure.
