TIZEN PHONE HARD RESET

One night i was using my samsung z1,my phone suddenly restart.The phone restarted but nothing worked.No matter
what i did i couldn't disable ultra power saving mode.so i did a hard reset on my phone and everything worked perfectly then.
I wouldn't recommend performing a hard reset unless your phone gets stuck in ultra power saving mode.All the installed apps
will be deleted if you did a hard reset.Thankfully no files in SD card will be affected.

  * Now press and hold Volume UP + Home button + Power button, and
    release them when Samsung logo appear.
  *Then you will see a menu"tizen system recovery" having 3 options

  * Wait until the phone restarts.
