No. original charger and cable . i see this problem in some Xperia SP in Iran and Persian Forums that they have same problems with xperia SP too . they say flash device using flashtools instead of update service and OTA because they cause bugs ! also i called Sony Guaranty in Iran and they say don't update by update service ! and come device to Sony office to flash it to solve some problems like heating and ... i don't know the difference . what is different between ways ? they all use same firmware

And how did you update?With the update engines from sony or with a flashtool?

I am also experiencing similar problem, but not always..pressing the on/off button got no effect..After 10 min or so, that got resolved automatically..It's not that. Initially the battery was totally empty..

Yep. That's how it is - for me, too (and for others).

The nicities of the 4.3 update - black screen on charge, LEDs lighing during call, messed up themes. Happens to many and no matter the reset/update/restore steps, it is still there.
