Upgrading firmware

[SudeepShakya]

I am upgrading to version 4.3 from mobile not from PC companion, so before upgrading what stuff is needed to do ??

Will it erase all my setting, data, downloaded apps, APN, MMS, SMS, phone number,..etc ?? My download is reaching almost 90%.

Backup everything on your computer and/or clouds as you could lose everything on your phone (pictures, videos should not be deleted) 

Update Service (SUS)

PC Companion (PCC)

Bridge (for Mac)

Thanks for reply,

So do i backup my app(+app setting/data) in my computer ?

[Uliwooly]

You can't backup your app/games data, unless you root your phone 

[SudeepShakya]

Will it create any problem after updata ?? Can now after update, app/games be transferred to SD Card ??

[Uliwooly]

Android doesn't support this feature anymore (to transer apps to sd card), you need to root your phone > partition your SD card > install an app that will allow you to do so, there are certain companies that had added this feature but its not part of Xperias anymore 

[SudeepShakya]

Sony SHOULD(MUST) add this feature, its a very useful feature with less internal memory.

It may be a downfall for Xperia devices.

[Uliwooly]

It has been requested before but its up to Sony's devs to include it on subsequent updates 

[SudeepShakya]

Yes, but it should be seriously considered.

4.3 update won't erase anything.
