[Q] Reliability of unbranded Android phones vs 'original' Samsungs
After my Samsung S2 suffered water damage, I now need to buy a new smartphone, and I had almost decided for the S3, which now costs only GBP40 less than the S2. Until I stumbled upon this: http://www.amazon.co.uk/S7189-MTK658.../dp/B00BG8F9G0
I have no problem with the idea of owning an "unbranded" phone, but I'm just worried that it might later turn out to be of substantially lower quality than the original. A colleague of mine owns a previous model of this Star phone (N7100), and he's been happy with it for the past year or so. After playing around with his phone a bit, it seemed fine to me, however I didn't get to test it in more detail (e.g. compare image quality of camera output with that from the S2, or see how stable the GPS fix is).
I'd have really liked to read a proper review for it (with benchmarks etc), or at least see a believable amount of user ratings. The Amazon product page has some good user reviews, but only 22 of them, and you can't really find much information about this model (or about the Star make in general) on the Internet.
What do you guys think? Is there reason to believe this phone would perform (visibly/audibly) worse than its closest Samsung equivalent, or that its life expectency would be shorter? Many thanks in advance for any help, I really appreciate it!
