well, i have a 3 month xperia Z1,before i upgraded to Kitkat, i had no bad experiences using it, but since after i upgraded to kitkat, huge problems flooding to my phone.i'll mention some problems i've been experiencing:
1. whenever i type a message or something, sometimes the virtual keyboard just runs itself, i type "A" then it turned out tobe "A-S-A-P" for instance;
2. i had issue recently on my camera lens, it apeears a dew, when i'm 100% all covers have been closed perfectly
3. the camera button, whenever i push it, it goes to camera app, but i cant capture any images using this camera button
4. yesterday i had issue with the power button, first it did not work at all, then it continued when i pushed it, it went to three times vibrating, just like when you push power button and the up volume button at the same time, but after i ignored it for few minutes, it went normal,,
5. last night, the camera app just open continuously, until now,
i went to my local sony care center, they said that they would check it again for about 1 - 4 months!!!!! imagine!!!! and btw i'm in Indonesia,,
i was desperate, so i just went to my friend to downgrade my kitkat, hopefully, all of those problems will be fixed,,
i love sony, but with this experience,, my previous iPhone 4 was the best phone ever, works well for about 2.5 years,, also my old Nokia...
