I use this phone for more than a month. Never know there's a group on lowyat,
Black Unit report in.

Anyone have touch screen not sensitive issues?
But after I stick screen protector i get from mainland, the problem seems solve =x

just realise there's a update today.
so far you i see you guys saying that zen ui is the only drawback?

I'm fine with ZenUI after using it.
But after updating my phone to the latest version, I few my phone draining power real quick and some problem with ZenUI.
After I reformat my phone, now back to normal.

So if anyone updated to the latest version, the best is to format your phone and run new.

Format = Factory Reset aka wipe all data.
I don't think the process is reversible.
Once you upgraded to KitKat, you can't downgrade to JellyBean on this phone.

So far my phone running great on KitKat.
But android always got a problem where AUTO run some apps on background.
I personally disable a lot useless app like amazon kindle, play book etc.
They RUN in background even I didn't use them / ever open them.

Battery life great.
Ram usage below 1000/1984mb
Some upgrades on Camera functions.
Note apps still retain which is great!
Other is just like normal to me.
Slowly getting used to ZenUI
