[Sony Xperia ZL] Rumman Shaikh:
Having updated the phone for a few days for now,it's time to review this latest update from Sony,so let's get going;)

First of all,

THE GOOD

- update came sooner than we all

expected

- transparent navbar/notification bar and improvised quick settings look beautiful

- Lockscreen now has customizable screens(pre configured)

- Task manager now looks more like the stock jellybean, but now small apps can be customized as per one's need also uninstalled from task manager itself,also widgets can now be converted into small apps

- Display now changes brightness more quickly resulting in better contrast in all lighting conditions (Sony changed the algorithms)

- Camera now gives better performance,that is it focuses more easily and quickly at the subjects,also the camera app now launches in less than a couple of seconds rather than 3-4 secs taken by previous firmwares (no mention of quality here)

- Messaging UI is tweaked a lil bit

- My Xperia, is added incase the handset gets lost,support for dualshock3

- 64gb SD card is now supported

- Stamina mode now works brilliantly and can save some serious juice for the device, overall the battery now lasts a little longer.

New feature,named magnification gestures is added for magnifying anything on the screen by tripple-tapping the screen,daydream is added

- UI for Movies is tweaked

- Wi-Fi connectivity issue is now fixed and does not loose signal at its will

- More options are added in smart connect app

And now,,,ofcourse

THE BAD(includes known bugs)

- Update came with more bugs then we expected

- Though the lockscreen is meant to be customizable,,it has a limited number of screens to choose from and we can't have screen of our choice(customizable,huh?)

- The keypad tones are still inaudible,& hands-free volume can still be annoying

- The swipe up/down to unlock message does not disappear on touching the screen and is annoying as it spoils the beautiful lockscreen

- Camera quality is not improved overall( I mentioned about performance earlier not quality,remember?),,though the camera now takes some decent shots(better than burst mode,now),,it still does not do justice to the hardware provided.. The photos look good in the mobile because of the Bravia engine but once viewed on other devices or computers,the shortcomings are clearly evident...noise is less here but photos come with too much softness for everyone's liking,,in low light and indoors this becomes worse..HDR needs some serious improvement,also photos are over-compressed resulting in a mere 2-2.5 mb/photo which is ridiculous for a 13mp camera.same can be said for capturing videos, which still allows us to take a 1mp photo while recording :P

- My Xperia can find your handset if it's lost.but it requires both GPS and mobile network to work simultaneously,, and there's no provision for doing it remotely,,meaning it's pretty much useless at this point.

- Though stamina mode now works more effectively,,there is a serious bug which makes the battery die almost suddenly making it reboot the device, and once it's rebooted it gains 15-20% battery,,which can make any layman laugh at your ZL :-S

- Also once a photo is taken from the camera app,,and you preview it from the thumbnail provided there,,doing a pinch to zoom will result in a bad lag(last for 10-12 seconds)

- And talking about lag,,the device now laggs in homescreen swipes(though mere,it's quite evident) and also in applications,and while browsing webpages.The device now scores less than the previous firmwares in almost every benchmark(some suggest benchmarks don't tell anything,but they can surely tell the difference due to the firmwares on the same device)

- Through systemcontrol app I found out that the first core now works more harder in standby mode(12-15% now,from the previous 2-5%) this suggests that the New firmware is more heavier on the hardware then the previous one's,transparent navbar and other visual tweaks can be the culprit here..this overall gives us an idea of the lag faced during homescreen swipes.

-More bugs to be found out soon:P

In all we can say that Sony did do a great job getting this firmware ready early as promised,but they could've done a better job, if they released it a little late(- the bugs)..

But we can be sure about one thing that there are a hell lot of firmware updates coming soon for us,,hope that'll get us rid of these serious bugs.;)
