[Sony Xperia ZR] effective:
Bought the ZR on first of august,and let me intreduce you my review for it :highfive: (sorry for my bad english tho :silly: ).

1 - SCREEN - Awesome and vivid colors thanks to the Bravia engine 2 integration(as someone mentioned no big difference between AMOLED screens when i compared them with my friends SGS4.No problems with the viewing angles eather.Max Brightness option do a great job on sunny days.(its more powerfull and bright after the 4.2.2 update - written in changelog).For a month and a half now not a single scratch.(hope i will keep it that way - the stock screen protector is awesome,the screen respons to every little touch i make even with a finger nail (great for girls too :victory: ) When screen is wet a single drop of water count as a touch so..yes its sensitive alot .A minus for me only is the black colour which is kinda greeny and i dont understand why but even my Xperia X8 had a better black colour.

2 - BATTERY - Its great when it comes to battery consumption.It is very low when the phone is idle (like 2-5% in the night) and it lasts me all day with avarage usage.I charge it in the night and when i go to work at 6 AM and return back home at 9 PM i have like 35-40% left.(i listen to music alot when im in the bus and i browse the web often,playing heavy games like 2 hours overall per day. Tested it playing non stop heavy games - yes battery drops pretty fast but..which phone doesn't right? :)Im quite satisfied with it.No disatvantages for me here.

3 - MULTITASKING - I dont have much to say here...2 gigs of ram and the 1.5ghz quad core are doing the job flawlessly. (up to 1300 mb free ram after 4.2.2 update / 1100 mb free on 4.1.2) No problems at all.Everything is smooth as butter ! :victory:

4 - CAMERA - Since i don't use the frontfacing camera i don't care about that its VGA (some ppl will disagree with that but..its a person's choice ^^).About the 13Mpx monster camera on the back..for me its just perfect.Very good and clear pictures with SAM enabled - which needs some tweaking from sony..not perfect but good.Disadvantage for me are the nightshots which are with much noise and are greeny as hell.SONY told us that a fix is coming with the 4.2.2 update,but i didn't noticed any change.Its still the same.Software improvement is needed here so we will wait abit since i saw that the Z1 night shots are not good enough too.We have the hardware but we lack a software.On Normal mod the low light shooting with some options changed are not bad at all tho. (compared with my friend's Xperia L the L is doing autstanding nightshots with 8mpx shooter so i expect some improvement from SONY :) )

5 - WATERPFOOFING - when i saw the IP 58 i told to myself - time for a swiiim and a water tasting baybeee.Im having a shower almost every day with the phone singing like crazy and listening songs from youtube.(im a hard music lover :highfive:) No problems in seawater eather.Just need to clean it with fresh water after the beach parties.And salt wont be a problem at all.When you have the guts to do in once .. you will love your phone even more ! Had a perfect underwater pictures and not a single problem with the touchscreen under the water.Every touch - recognized.Some people reported flaps coming off by themselves and so on.Not a single problem for me - charging the phone every day+using the headphone jack constantly (music lover :eek:) and the flaps are perfectly fine and stable for me.Just clean them well from the dust that is piling from the inside.

6 - LOUDspeaker and CALL volume - For this i saw many many people complaining.I don't know if i am lucky or anything else,but i really don't have any problems hearing the person im talking to when im outside.Using Clear Phase and xLOUD options ON,so again not a single problem.Only thing is when someone call's me just after a swim with the phone - yes the volume is low,but that is normal.After 10 minutes everything is back to normal.The stock headphones provided from sony were not so good for me since im a vocal dubstep lover and i just..need to hear the deep base..with good headphones and a good managed program the sound is superb.

7 - SIZE,WEIGHT - Last phone - XPERIA X8 - soo i was like WTF this is HUGE .. :eek: but after some usage everything is fine.Not heavy and was searching for a device with descent screen and good statistics,so the ZR was the perfect choice.Overall for a device that a person use ofet and relie on it for a lot of things nowadays..this is my little love here.Hope i helped with this review for someone who is willing to buy the device and maked some things sorted out and clear for him.Cheerzz :highfive:
