After some time of playing around on my ZL 4.3 build, here is what i want to conclude here:

1. Advantages/Improvement
-Option to add One-hand typing
- Camera features like Z1 in 4.2.2, which got AR effects, MotionShot, Social Live and others.
- Camera burst shot increase the resolution in high speed. Previous is around 1MP now is on 9MP. which is great.
- Small apps can be open several apps at the same time.
- Theme can be additional download in playstore.
- Brightness toggle now is appear in bar mode. Can increase/decrease by own preference. Previous if press it, will only get 100% or 25% brightness. If need set 50% need enter settings and adjust
- Manual mode seems improve quality of photo. Not so significant photo processing in my attempts.. Superior auto and scene mode was still processing the photo and make it grainier..
- Self timer in camera settings will present the options once u choose. E.g. Set 10 seconds for self capture, after capture was still 10 seconds on next capture.. no need always reset again..
- Performance in overall seems smooth.. not much complaints.. I won't do benchmarks, coz i doesn't believe it in real practices.. just wont lag.. Temporary all function are works nicely..
- Photo widgets changed newer.

2. Disadvantages:
- Capture image while in video recording was still in 1MP only. which not so good for me. Superior auto was fixed on 9MP which cant be adjust by users.
- Burst mode only can be actived in superior auto mode
- Backup data in 4.2.2 was cannot be used in 4.3.. Beware of it.
- No screenshot option in power menu

1. The backup like msg, call log, bookmarks in browser and others by the sony stock backup & restore apps wont works. not about the google backup..

2. yes.. brightness toggles drag left-right.. please check my screenshot on above..

im using stock msg apps. hmm, these im not sure.. haha.. maybe u can try it out in future..

LOL.. that is the official sony tester build 4.3 ROM. so its not 3rd party.. consumers build are 99% same i believe, the only 1% will be bug fixes if there are any. Wont lost the BE since we no need to unlock our phone bootloader.. it just download the FTF and flash like normal..

I repeated, its Tester build. So in future, we can flash back to android 4.2.2 fw.67 MY, and update to official consumer build when its rolled out.. soon i think will get the update from Sony in coming weeks.

**temporary didnt found any problematic bug. just 1 small things but didnt affect our daily usage at all.. should say 99% is work right now.. i love this 4.3 update.. wondering the 4.4 update in future..

hmm.. actually i just wish sony can fully utilised the current sony things.. small apps, additional theme, PSM, can be expanded more.. hopefully AR effect in camera can be expand more as well..
Social live feel lag in picture..

enjoice gais 
4.3 rooted by [NUT]

Does 4.3 improve the performance of Album? Scrolling pictures, opening etc.

My wife's Galaxy nexus gallery performs faster than my ZL

oo.. when i try install apk like LINE AR effects, the words was located a little bit upper than usual..

Camera photo size 13MP around 3mb each now..

not recommend to flash android 4.3 tester build right now.. hope u all stay back in android 4.2.2 first..

Found something bad.. dont ask why.. just dont flash it.. wait officially 1..

Regards,

its hard brick my phone now.. LOL

i have no idea whats happen.. but i think not good to try it.. i need find sony service centre if i still cant fix it by tonight..

Guys.. Normaly if vharging phone on 11% - 20%,

Its take how many hours to full??

Sounds about normal .. USB output about 500mA right? Z battery about 2xxx mA ?2xxx/500 = min 4hours. In fact, if you are actively using your Z while connected to USB, I think the battery % will even drop eventhough it's charging (output usage > input).

My ZL came with a 1.5A output charger, but I used a 2A one for faster charging. Hope it doesn't burn out the phone.

If use stock charger, the phone should be fully charged within 1-2 hours assuming you're on 20% or less. If longer you might want to have the charger/cable checked. Touch wood it's not the battery/charging parts on the phone that is dead.

How to check battery health??

haha.. i dunno.. maybe its my battery problem.. sudden death issue.. i flashed back to .67 fw ady..

if i unplugged charger, my phone will auto turned off..

hi bro, im planning to unblock the bootloader. i miss the smoothness of aosp
already backed up my TA
any other precaution?

thanks. the rest i will follow the guide on xda. btw, how to revert back to stock rom? just flash via flashtool?

If I have unlocked the bootloader on my phone then I reflash it to the original software... Will my warranty still valid?

do i need to backup my external sd card?

ok, will proceed to unlock the bootloader
