hi guys,
try this its work for me .

Just go to settings>apps>All Apps> and clear the data of Download manager and stop the process, then go to Google services framework and clear the data and stop the process and shut down the device from there itself. Turn on and check again.

Mine after up to 4.4 signal and WiFi bar is white compare previous 4.3 when have the internet will bcome blue, any1 also like this?

the pin broke? you can use other phones' charger as well. but if you want the exact same one, I think the KJ service centre sells them.

you can probably do a quick search at lelong or mudah, but there are too many 'original' counterfeits now.
