Hi. I have LG L7 and i have some problems. While i can't connect with wi-fi to internet , i tried to install some games. i downloaded apk + data files from internet and i tried to copy data files in Android > Data , but i can't do this, some files are copy, but not all and the game can not run. what's the problem ? the same problem if i try to copy on external card. i tried to copy data files from grand theft auto 3 and asphalt 5. but the most important think is that i could copy some music to external card, and it works. apk file works to copy, but only data files, when i tried , doesn't work, why ? my phone don't have root.
