I am a SGS2 user and thinking of my next smartphone update. Being using SGS2 since launch about May 2011.

Things I care about the next upgrade are removable battery, great camera, great screen. I prefer dedicated shutter button, though it does not matter. My SE C510 can take better images vs sgs2 at 3.2mp setting which says something about the C510.

Based on the phone comparison, I can see ZR quite a good value compared to SGS4.

However I don't know how good is the picture quality compared to the S2. I actually wanted a Z1, but they don't make it with a removable big battery. I don't mind water resistant or not. I need the removable battery as I use the phone a lot, especially on business trips as a theter device. Currently I change the SGS2 battery about slightly more than a year. Now on my third battery (since launch). With light usage I get about 14 hours per day on the SGS2 on new battery. Which covers most of my normal daily use when not outstation. By the time I go to sleep at 11, the phone has <5% battery left. When I go outstation, I'd get about 5 hours of battery (if lucky) which results me in killing the battery off even more with charge while using it-car charger/power bank/laptop usb/wall mounted theter etc. Battery goes down very fast in areas with poor connection. I assume the S2 is using a lot of battery power trying to get a strong connection.

Since SGS5 should be launched in the next 2 months, and the ZR was first available May 2013. I assume a normal phone cycle would be a May 2014 for the ZR successor to come.
My questions are:
1. How good is the ZR's camera vs the SGS2 or even the SGS4's camera?
2. How long can the battery last last?
3. Should I hold out for the ZR's successor, since it is already Jan and May is not far off.
4. The ZR phone release is May 2013, but when practically can purchase the phone earliest?

Thanks for the reply. Last question I meant was, the phone released date was May 2013. But released date does not equal to date which you can actually purchase the phone. I was wondering when did this phone became available for purchase in Malaysia

Does this phone have problems? Sent back for warranty?

I see. Well, if they give you free new phone, that would not be bad. But the inconvenience is something else. I don't like the SGS4/3 shape, and I like the shutter button. So I will pass this one for now, until I find a better reason to upgrade
