The only advantages that IMHO the S3 mini has over the Nexus are:
- smaller size (if that's important)
- microSD slot
- smaller size (sizewize, 4.5-5 inch is slowly becoming my sweet spot)
- poor community (I don't want to ofend anybody)
- poor support from Samsung (Nexus might even see official Android 5)
My advice for you is:
Make a list of things that matter for you: screen size, processing power, microSD slot, software updates (official or not), etc). Compare the two phones over at gsmarena.com or somewhere else and check which phone better suits you. Now check for reported problems. Sleep a night or two on all this info and in the morning place the order.
Personally I have two things against the Nexus: no microSD card slot and problems with the flash memory (search for problems with trimming
). But, giving that I still have it, I can live with those.
Have a nice day!
