Last updated on: October 13, 2017 · First published on: October 13, 2017 Leave a Comment

How to wipe Galaxy S8 cache partition?You can wipe Galaxy S8 cache partition to solve many problems in Galaxy S8 and S8+ by yourself without affecting your data, or settings.

This Galaxy S8 how-to guide first explains what Galaxy S8 cache partition is and why and when you may need to wipe Galaxy S8 cache partition, then shows you how to clear Galaxy S8 cache partition.

What is Galaxy S8 cache partition?

Galaxy S8 cache partition in Galaxy S8 and S8+ is a special (and reserved) part of the phone storage. But it is not user accessible in normal mode.

As suggested by the name, this special partition stores and serves the cached files for the phone. This is needed in all Android phones to speed up the apps.

For most owners of Galaxy S8 and S8+,  it is not necessary to know the existence of such a cache partition. Of course, they do not need to wipe Galaxy S8 cache partition in the lifespan of the Galaxy S8 and S8+.

The cache partition is normally well managed by the Android system. The partition will be refreshed automatically for example, when a major update is applied.

But occasionally, something in your Galaxy S8 or S8+ may go wrong and you may try to clear Galaxy S8 cache partition to avoid a factory data reset.

When you may need to wipe Galaxy S8 cache partition?

As mentioned, normally Android is smart enough to properly manage the cache partition in Galaxy S8 and S8+.

How to use Galaxy S8 safe mode?

Last updated on: September 8, 2017 · First published on: September 8, 2017 7 Comments

Galaxy S8 safe mode helps you troubleshooting issues related to third-party apps installed by you.

You can identify whether the problem is caused by the system or by third-party apps.

This Galaxy S8 how-to guide explains the details of Galaxy S8 safe mode in Galaxy S8 and S8, two ways to reboot Galaxy S8 or S8+ into safe mode,  and how to use and exit Galaxy S8 safe mode.

What is Galaxy S8 safe mode?

Sometimes, your Galaxy S8 or Galaxy S8+may behave in some odd ways.

And you want to find out whether such problems are caused by third-party apps or pre-installed apps.

Galaxy S8 safe mode is the right tool for such problems.

Like in other Android phones,  Galaxy S8 safe mode is a special mode for Galaxy S8 and S8+. Within this mode, all third-party apps (including some pre-installed Google apps) will be disabled temporally.

So, only some essential apps from Samsung and Google are enabled in Galaxy S8 safe mode.

If you still experience the problem in Galaxy S8 safe mode, then you can conclude that the problem is caused by the firmware or some of the  essential apps. You may have to reset Galaxy S8 or S8+.

If the problem disappears in safe mode, you can then conclude that the problem is very likely caused by some apps installed by you.

Unfortunately, Galaxy S8 safe mode can only tell you whether the problem is caused by third-party apps or not. It is unable to tell you which app is causing the problem.

Two ways to reboot the Galaxy S8 or S8+ into Galaxy S8 safe mode?

There are at least two different ways to boot into Galaxy S8 safe mode.

Method 1: Use power button options to reboot Galaxy S8 and S8+ into safe

How to power on, power off and reboot Galaxy S8 and S8+ even when phone hangs?

Last updated on: April 13, 2017 · First published on: April 13, 2017 42 Comments

You may know you can use power button to power on Galaxy S8 or power off Galaxy S8 and S8+.

But do you know how to power off Galaxy S8 and S8+ if your Galaxy S8 or S8+ hangs and does not respond to power button?

This guide will show you how to power on, power off and reboot Galaxy S8 and S8 at any situations, including when the phone hangs (power button is not responsive).

Use power button to power on Galaxy S8, power off Galaxy S8, and to reboot Galaxy S8 and S8+

When Galaxy S8 or S8+ is powered off, you can always press and hold power button for a few seconds to power on (turn on) the phone as shown below.

Please note, Galaxy S8 (and S8+) power button is located in the right side of the phone as explained in Galaxy S8 layout and Galaxy S8+ layout page.

Some owners may press the Bixby button, which is located in the left side of Galaxy S8 and S8+ and below volume buttons,  mistakenly for power button.

When the phone is powered on, if you press and hold power button for more than 7 seconds, you will then reboot Galaxy S8 and S8+.  This is considered as forced reboot.

If you press and hold the power button for 2-4 seconds, you will get the Galaxy S8 power button options:

  • Restart. Tap this button (marked as 2 in the screenshot below) to reboot Galaxy S8 or S8+. This essentially is powering off Galaxy S8, then powering it on.
