Galaxy S4 firmware update... again?

[Anonymous]

Hi,

Can anyone tell me what the lastest firmware version is for an S4 on o2? I currently have I9505XXUEMK8 but I believe the latest is MKE and having trawled the forums I cant see if this is available via o2. Both the OTA update on the phone and also Kies say i have the latest version, although I'm not so sure.

I'm wanting to try and upgrade because of some stability issues with Wifi etc after updating to 4.3 in November. If anyone has any other suggestions on fixing 4.3 stability issues then I'm all ears (factory reset?)

Sorry for asking something which has probably been covered before.

Cheers

Hi there MK8 is the latest on O2 we would always suggest a factory reset after a software update if you haven't done that I would do it it sorted my s4 out after the upgrade

MK* is the latest UK firmware but your CSC makes no sense, so I think you've written it wrong.
There is a wifi bug in 4.3 which effects phones connected to some routers.
Clearing cache from recovery mode (might have to do it a few times) does help sometimes and a factory reset should always be done after updating any firmware.
