Samsung Galaxy S4 has the simple recovery mode just like its brothers and sisters ~ Android system recovery <3e>. It can perform several essential tasks like reboot system now, apply update from ADB & external storage, wipe data/factory reset, wipe cache partition and apply update from cache. Definitely not a match for ClockworkMod recovery – CWM or Team Win Recovery Project – TWRP which provide lot of features like Nandroid backup, install custom kernel, ROM and other more. But it is your saver if you installed Samsung Galaxy S4 Retail Mode (you know what I mean if you installed it).

Samsung Galaxy S III Android system recovery <3e> mode is a simple recovery mode that comes by default. It may not have lot of features compare to ClockworkMod Recovery Mode. But it does have the ability to perform several simple tasks like apply update from external storage, wipe data/factory reset, wipe cache partition, apply update from cache and reboot system now.
