This Galaxy S20 guide explains what Galaxy S20 recovery mode is, when you need to use it, how to reboot into the recovery mode, and how to navigate and exit the recovery mode.
The Galaxy S20 recovery mode is identical on all 4 Galaxy S20 modes: Galaxy S20, S20+, S20 FE, and S20 Ultra. So this guide applies to all these phones.
All Android phones and tablets come with a recovery mode. Galaxy S20 is not an exception. Android vendors may add or remove some features in the recovery mode.
On Galaxy S20, you can use the recovery mode to (as shown in the picture below):
We will explain some of them later on.
Galaxy S20 recovery mode is NOT designed for normal users. Most Galaxy S20 owners do not need to access the recovery mode.
But occasionally, you may need to use the Galaxy S20 recovery mode to solve some problems by yourself. Otherwise, you may have to visit the service centre.
Please make sure you know what you are doing when in the recovery mode. You may easily wipe your data in the recovery mode.
This is the most common and safe usage of the Galaxy S20 recovery mode.
When Galaxy S20 behaves weirdly, you may try to wipe the cache partition. Normally, you should try the Galaxy S20 safe mode first.
Of course, clearing the cache partition only solves issues caused by caching. There is no magic. But it often solves many issues before you have to do a factory data reset (FDR).
If you do not know about sideloading Android update, you should NOT try it. In this case, you should always check update in Settings — Software update —Download and install.
For a few seasoned Android users, they may try to sideload system updates (e.g., Android 11 update) saved on the PC or micro SD card in the Galaxy S20 recovery mode.
Again, it is NOT required to enter Galaxy S20 recovery mode if you want to reset (factory data reset) Galaxy S20. You can do it from Settings — General management — Reset — Factory data reset.
But if you forget your password/PIN/pattern, you can only reset it remotely with Samsung's Find My Mobile, as explained in this guide.
Unfortunately, some Galaxy S20 owners may forget to add a Samsung account to the phone before he/she is locked out (or forget to enable Find My Mobile and remote unlock). So, nobody can unlock the phone any more. In this case, you have to use the recovery mode to reset Galaxy S20.
Occasionally, Galaxy S20 may fail to boot successfully. In this case, you may also have to use the recovery mode to factory data reset Galaxy S20.
Please note, when you factory data reset Galaxy S20, all data and apps installed by you, except system update will be wiped out. You will lose ALL data if you forget to back them up.
In addition, due to Android device protection since Android Lollipop 5.1, you MUST use the Google account existing on the phone (when the phone is reset) to set up the phone after the factory data reset.
When you update Galaxy S20 or set up Galaxy S20, you may notice there is a stage called “optimising app”.
This process actually provisions the app for the system by generating the Dalvik cache so that apps can run nicely (and quickly) with the current system.
But occasionally, something may go crazy.
You can use Rapir apps in Galaxy S20 recovery mode to manually re-optimize apps.
To boot into Galaxy S20 recovery mode, you may follow these steps.
You may follow this guide to power off Galaxy S20.
Please note, Samsung added the power menu button in quick settings panel since Android 10 update. So, it is not required to hold the Side key on the right side of the Galaxy S20 to access the power menu. The power menu (aka power-off menu, power button options) is also available in the Assistant menu.
Remember, if you hold the side key for more than 7 seconds, Galaxy S20 will reboot, not power off.
After Galaxy S20 is powered off, you can then hold the Volume up button AND the side key (i.e., hold two buttons on the right side of the Galaxy S20), as illustrated below.
Please note:
You need to hold the two buttons until you see the recovery screen. It usually takes about one to two minutes.
You should see the recovery mode screen, as shown earlier.
You cannot use touchscreen gestures in Galaxy S20 recovery mode. You have to use the volume key and side key to navigate in the recovery mode.
Press the volume up and down to navigate to different entries in the recovery menu. Then use the Side key to confirm the selection.
Please note, there are no undo features in Android. You may lose your data or wipe the phone unintentionally. So, you need to make sure you know what you are doing in the recovery mode.
In the recovery menu, you can choose:
You should be careful when holding the Side key in the recovery mode. If you navigate to an entry inadvertently, holding the Side key may activate it.
