this is my situation : i have two LG G2 both white , the first is D802 16GB , and second is the korean version K320S 32GB with micro SD and removable battery etc ...
this is my story , on week ago i bought a white G2 D802 16GB from a store in my city , and it is really good , lag free i score everytime in antutu more than 36000pts no issue , 3 days ago a friend of me was travelling to korea and he bought 2 LG G2 koran version and when he come i bought from him one i couldnt say no to a 32GB with microsd etc ..... when i powerd on the korean he upgraded to kitkat 4.4.2 ... i decided to use it 48 hours and decide wich one to keep , ( On paper the decision is easy i think all of us will go with the sexy 32GB + sdcard) but i didnt had a good feeling with the korean it lag time to time score on antutu never more than 30000pts .
now if you are my this situation wich one will you choose ? im afraid to keep the 16GB and when 4.4.2 come he become laggy .
what you need to know about how to i use the phone : i m not a big music fan i listen rarely to musique on phone , i use it a lot for work , emails reading , and time to time playing games thor , iron man etc ....
I cant keep them both they are similar in look its a wast of money ,i have to sell one .
i attached here my antutu scores and other info about both phones .
thank you very much for giving me your time .
