Confirm all those LTE bands are missing in the Lte 510 firmware. So no hope to have LTE functionality.

iPhone 5 in MY all is LTE supported right? I can't test coz I no have LTE nano sim

Haha love this, with Pencil! 

This is bad news. 

Unlock bootloader void warranty already.

depends how good ur white lie is 

Flashing wrong ROM and if the phone is completely dead, easier to claim warranty depends on how you talk. hehe...

AP set has LTE model right? If u don't mind..

Not yet got refurb set lar....still too new in the market.

I always insist on sealed AP sets n I always get it. So ask for it when you want to buy.

Exactly uncle. I too prefer sealed sets so that I'm satisfied that nobody ever touched. Apart from the dude who packs into the box in the final assembly line. Or is that also done by robots?

Agreed.  Problem is many users still think they are using Windows OS when the approach by Android is completely different. Google words are ram is meant to be used n any unused ram is wasted ram. Clearing ram will not benefit except giving user a psychological feeling that is good to do. This phone has 2gb ram n it is more than enough to cope. Worst is to use app to do such stuff as these app are basically resources hungry,  consume battery n only gives a good feeling to user that they think is right thing to do.
Those sceptical just Google yourself why clearing ram n using task killers is unnecessary in Android

IMHO, it's not just "RAM Full" but rather CPU cycles are occupied. The CPU is not free to attend to your app's request, so it has to wait. This is called a "wait state" and is a very bad thing to CPU designers. This is the lag.

As I said before, RAM is like your table top. You are the "cpu". You can put all your work on the table, but if you can't work on it, it won't get finished.

I've never experienced buying AP sets before apart from 1 Nokia N8 which I bought 2-3 years ago cause I was abit tight on budget(use my own money then). Nowadays I only purchase from authorised distributor.

in android, is not entirely ram prob...is app oso need be optimized so it use the resource properly. install proper apps sure wont face prob as android activity lifecycle is very simple n manageable...is coding tht usually messed up with the lifecycle

It's both RAM + CPU cycles. Back to table metaphor, you have plenty of stuff laid out on the table, but you can either do 5% work on each of them round robin, or work 100% on one before working on the next, or something in between.

Even with multi-core CPUs, the OS is responsible to schedule jobs/threads to hand off to cores. Maybe Android or the hardware still has issues? I'm just thinking aloud.

bloatware is also the cause. remove the bloatwares as well will do the trick. i freeze all bloatwares in phone n with all the customization i made, i juz use around 1GB of RAM.

The fake hang always there, I no wanted to flash anymore

When I tick the option, the screen become dark...

yea... i agree.. screen become darker.. not bright..

Darker is protect eyes too, too bright will make eyes tired

Different screen manufacturer I think

Ok,  this is my finding after done the read

1)TA (Trim Area) is config file for S1 Loader and Baseband (Radio)
To modify this we first need to disable security check in bootloader.

2) TA (maybe) comes with phone or it generates itself on first boot,
Also TA files is signed by IMEI.So to flash other TA we need to modify IMEI first.

3)Just to say this cant brick phone just disable radio FOREVER!

So can lte can be enable? Maybe,  but the risk too high, lol. Better stay with 3g since a wider coverage + better saver+quite fast too, i can live with that.

Don't call me. I am officially retired from Sony phone. No longer have XZU and XZ.

The only left out is XTZ.

sold my XZU de...Bye bye XZU

So many ppl sold XZU

What to do ..fall in love with Note3..

My six sense told me i'll like it.
