Hi guys. Newbie here. So I've rooted my Samsung galaxy s3 and have been trying to install an app. I've read in many places about simply copying the .apk file to the system/apps folder but I can't seem to find this folder on my phone. On my sdcard (using ES file explorer), I see folders such as Alarm, Android, DCIM, Media, smvvm, etc. but no System folder. Please tell me where I can find it. Thanks!
