Hello, well I used to like my Z1s until the kitkat update, after that it just malfunctioning.
1. Auto rotate works just sometimes, whenever it feels that it wants to work. So what is the point of having a big screen if i cant used it??
2. When I have the autobrightness on the screen starts to "blink" sometime to time. Actually what it does is that it goes all the way from superbright to really dim really fast up and down again and again...
3. The worst of all, The camera just doesnt work. First it was showing a "camera not available" message. but it worked some time to time... I look on the internet and someone says to erase all the data for the camera... oh well that actually worked! yey! but a few days after that it was even WORST!! now when I open the camera is just black, Im able to move all the options but the camera doesn't work.
4. Now this doesn't have to do with the update. The protector for the charger port just disapear. One day I take out the phone from my pocket and the thingy was no were to be found.
So what Im suppoused to do now? 
But my phone was perfect before the update!!!!
Why in the world will Sony send me a defective software?
and as I stated in my message I did the clear data thing and worked only for a couple of days and then it came back...
Also I have noticed a reduction on the performance of the battery...
Why Sony ? WHY?? 
After finding some time to do the backup and dowloading the software I did it!.... it messed up a little bit with my pictures and when trying to move everything back to my phone I had to do it a couple of times until it did it right. But It worked! YEY!! I was so happy I have the phone I'm paying for back to normal use......... well almost.... after three weeks of use the problem with the dimming came back and also the auto-rotate stoped working... I really don't know what to do at this point , Can someone pls help me out?
