I have galaxy s4 i9500 . it lags and it's not fast , so I wanna change it but I have some questions .
I've taken a look at all the threads in this department . I found out that the battery is impressive and the camera is so good that you can take beautiful pictures by this small phone . That has amazed me because this phone is small and good and that's what I was looking for . On the other hand , I have noticed that there is alot of problems especially after updating to kit kat such as the flash problem , the speaker voice problem .
I don't really know if I should buy this phone or not .
If you help me , I will really appreciate it but please let me know If you have formated your phone after updating or not because the formating will resolve alot of problems .
last question is : What do you think about the performance ? is it powerful ?
thank you so much (:
