Solve Selected SD Card By Your Key Input

As you are here, it means your phone keeps posting the “Selected sd card by your key input” error. If you are facing this issue, you are not the only one.

Many Samsung phones have this issue. Many Samsung users reported that they have left the phone in their pockets, bags, or on the table and when they picked it up, they saw this error.

This is a common issue, especially in the Samsung Galaxy S10 series. Don’t worry, in this tutorial, I am going to show you how you can easily fix this issue.

What Is “Selected SD Card By Your Key Input”?

You can see this message in the phone’s recovery mode. You can see this message when your Samsung phone accidentally boots into recovery mode and tries to use something from the SD card. Sometimes the phone gets stuck in this text or completely freezes. This is frustrating as many users don’t know how to exit or get rid of it.

Why Does It Happen?

People accidentally press certain key combinations and end up in the SS RDX Mode. Android devices have different modes designed for specific purposes. For example, Fastboot mode for flashing firmware or Recovery mode for factory resetting the device.

But when it comes to Samsung, you can see the difference as it uses Download Mode instead of Fastboot mode for flashing firmware via Odin. In recent Samsung phones, Samsung came up with this new SS RDX Watchdog Reset Mode.

How Can This “Selected SD Card By Your Key Input” Issue Be Fixed?

When I was researching this situation, I found that people tried different things to solve this issue. Some devices came back to normal mode after a simple reboot, some needed to do something extra, and some didn’t solve the issue because of hardware failure.

If you accidentally triggered the SS RDX key-combination and entered into RDX mode, you can recover from this state. Follow these fixes below.

Fix #1: Doing A Simple Reboot

Try to reboot your device by holding down the Power key longer until it reboots. Sometimes a simple reboot can fix this issue. If you are unable to reboot your device then try the next fix.

Fix #2: Using The Key Combinations

You can use the key combination to exit this mode. Follow the steps below.

  1. First, press and hold down the Power button and Vol+ button for 3 seconds.
  2. Release it, press and hold down the Power button and Vol- button for 3 seconds.
  3. Repeat the steps when brought back to the RDX Mode.

Fix #3: Drain Your Battery

If your key combinations do not work or your device freezes, you can drain your device’s battery to shut itself down. This will break the frozen state of your device and let you start your device by pressing and holding the power button.

Fix #4: Do A Factory Reset

This fix may not be needed if your phone starts normally upon a successful reboot. But if your device constantly reboots into SS RDX Mode, you may need to Factory Reset your Samsung device.

To factory reset your Samsung Phone, you need to boot into recovery mode. To enter into recovery mode and factory reset your Samsung device, follow the steps below.

  1. Power off your device. If you are unable to shut down your device, drain the battery completely. Then connect the charger and charge your device around 2-3 percent.
  2. Once the device is turned off, press and hold the Power+Volume Up+Bixby buttons simultaneously. If your device doesn’t have a Bixby button, then press and hold Power+Volume Up buttons.
  3. After booting into Recovery Mode, use your Volume buttons to navigate the menu. Select the “Wipe data/factory reset” from the menu and press the Power button to confirm it.
  4. Now select “Factory data reset” using the Volume down button and press the Power button to confirm it.
  5. After that, reboot your device and your problem should be fixed.

What if the above fixes don’t work?

Some users on Reddit and XDA confirmed that they were unable to solve the issue and none of the above solutions worked for them. This turned out that their devices had hardware issues and were unable to resolve this situation.

In this case, if you have a warranty left for your device, send it back and claim your warranty. If you are out of warranty, then you can visit a good repair shop to diagnose this issue.

You can also try flashing the firmware if you know how to do it and have the proper firmware on your device. But it is not recommended unless you know what you are doing.
