How to Soft Reset LG L90 D405
A Soft Reset (or Forced Restart) differs from a Hard Reset (or Factory Restore) in that it doesn’t delete any essential data from the smartphone or tablet but you may lose some RAM or temporary data, for example any unsaved game progress or the page you were viewing on a website.
A Hard Reset on the other hand would only be required when you want to wipe all data from the device, starting it over.
1. In order to soft reset your LG L90 D405 you will have to press and hold power button, (remember to do that on unlocked device)
2. There should appear menu on the screen.
3. Now please tap on Reboot option.
4. And this is it, now wait for your device to reboot itself.
Soft resets are usually conducted in an attempt to fix malfunctioning applications or because they're required for software installation.
Soft reset contrasts with hard reset, which removes all user data, settings and applications and returns a device to the same state it was in when it shipped from the factory.
