Hi. Ive used this phone for the last 2.5 years. Is a great phone if you have small/thin fingers. The battery lasts 1 day as I use it. you can pay with the phone at the store, the case is really slippery so you need to buy a cover ( once it falled down from my pocket when I was sitting on a bench and damaged one corner of the phone) . Compared to my S advance, when I turn on the data, the s advance freezes for about a min until it gets his updates, but the s3 neo keeps rollling. When I plug in the charget. the s advance responds very slow and freezes.but the s3 neo works ok.the s3 neo works on android 4.4.4 kitkat.thanks for reading
