5) Get ES File Explorer from the Play Store. Tap the hard key for menu, scroll down and tap on Net Manager. Tap on Settings at the bottom, select 'Use the system AP setting', enter an SSID (recommended to be short with no spaces, like 'MyName_GS4_Active'), and a password. Tap on OK. Tap on the back button. Tap on 'Create a hotspot network'. It will say 'Establishing Network...turning on', followed by 'Now you are using AP, SSID is...', AP password:, and an 'Exit' button. It may say 'Unfortunately, Settings has stopped' after this, but IGNORE it. Your hotspot is still active - look at the top left of the phone, you will see a wifi symbol in a blue icon, this is your indication that your hotspot is working. WORKS PERFECT!
