power on, power off, and reboot Galaxy S10 even when the phone hangsWhen Galaxy S10 hangs, you can hold the Power button AND the volume down button for more than 7 seconds to reboot the phone forcefully.

There are a few other combinations of keys (buttons) that you may need to know to power off, power on, reboot, reboot into recovery mode, or reboot into download mode on Galaxy S10, S10+, S10e, and S10 5G.

This Galaxy S10 how-to guide explains how to reboot Galaxy S10 when the phone hangs, and other key combinations for powering on, powering off and rebooting Galaxy S10 (including all 4 Galaxy S10 models).

How to reboot Galaxy S10 when the phone hangs?

Although it happens rarely, Galaxy S10 may hang (not responsive), just like other electronic devices or other Android phones.

If this happens to your Galaxy S10, you may also find the phone does not respond to the power button as well.

Up to Galaxy S5, Samsung used a removable battery in their phones and you can remove the battery to force a reboot.

But since Galaxy S6, Samsung has switched to non-removable batteries. And therefore, the battery removing method is not working for Galaxy S10.

So, when Galaxy S10 hangs (even not responsive to the power button), you can hold the Power button and the volume down button (2 buttons), as shown below, for more than 7 seconds to reboot the phone forcefully.

Technically, holding these two buttons is equivalent to removing (and putting back) the battery.

Using the power button and power button menu on Galaxy S10

Normally, you can press the power button on Galaxy S10 to:

  • Power on the phone (when the phone is off).
  • Wake up the screen (when the screen is off).
  • Turn off the screen and lock the phone. (when the screen is on)
  • Take photos in the camera app (if you enable it).
  • End a call (if you enable it).

If you quickly press the power button twice, you can launch the camera app. This is called Galaxy S10 camera quick launch.

You can also call out the power button options (power button menu)  as shown below by long press the power button for about 2 seconds.

In Galaxy S10 power button menu, there is no shortcut for the screenshot. This is different from the stock Android Pie. If you need to take screenshots, you may check this guide.

Please note, normally, you need to use the Power off button in the power button menu to power off Galaxy S10.

The Reboot button allows you to reboot Galaxy S10 gracefully. Reboot Galaxy S10 gracefully will not lose any data. But if you reboot Galaxy S10 forcefully, all unsaved data will be lost.

If you hold the power button for more than 5 seconds, Galaxy S10 will reboot.

This Galaxy S10 camera guide explains the Galaxy S10 camera settings and shows you how to use them.

Because the camera app in Galaxy S10, S10e, S10+, and S10 5G are almost identical, this guide applies to all 4 Galaxy S10 models although only Galaxy S10 is normally referred to.

Why do you need to understand the Galaxy S10 camera settings?

Samsung revamped the camera app in Galaxy S10 as part of the brand new  One UI for Galaxy phones with Android Pie (Android 9.0).

So, if you just migrated to Galaxy S10 from other Android phones, or from Samsung Galaxy phones with Android Oreo or older versions, you are facing a very different camera app.

Compared to other Samsung Galaxy phones with Android Oreo (Android 8.0),  there are many changes in Galaxy S10 camera app as explained in this guide. Some changes are reasonable and make things better. But a few changes may be undesirable.

To fully utilize the features packed in the Galaxy S10 cameras so that you can get the best possible photos, you need to adjust some Galaxy S10 camera settings depending on the situation.

For example, you should enable shape correction for the ultrawide camera to reduce the distortion.  But the option is not enabled by default in the camera app.

How to access Galaxy S10 camera settings?

In the Galaxy S10 camera app, you can tap the Settings icon, as shown in the screenshot below, to open Galaxy S10 camera settings.

  • Intelligent features. These features, scene optimizer, shot suggestions, and flaw detection,  intend to make your camera smart and therefore help you get the best possible photos automatically if enabled.
  • Pictures. This section includes settings for photos including motion photos, the action for holding the shutter button and photo save options.
  • Videos. The settings in this section are about videos including rear video size, front video size, advanced recording options, and video stabilization.
  • Useful features. Everything else is included in the section of useful features. They include HDR,
