Galaxy S7 Edge Power and Home buttons unresponsive after getting wet

Problems: Today I dropped my phone in water for about two seconds and quickly dried it off. All of a sudden my power button no longer works, nor does my home button and now my keyboard has started to lag dramatically.

Troubleshooting: First off, the Galaxy S7 Edge is water-resistant but not waterproof, which means that someway, somehow, water can still find it’s way into the device and mess everything up. The charging port is the favorite gateway of liquid and dust so even with its IP67 rating, if the phone got dipped in water with the charging port unprotected, it will probably suffer from liquid-damage.

Just reading your description tells me that you’re positive the problem started immediately after the phone got wet. So, it’s very much possible that the Power and Home buttons are now suffering from the symptom of the liquid damage. The lagging of the keyboard, however, can be attributed to a possible firmware issue that may have been triggered by some hardware issues that resulted from liquid damage.

Please note that water-damaged phones should be handled by a technician who do further test the device and inspect it to know the extent of the damage and whether or not it can be fixed by blowing hot air over affected components. Needless to say, you need to go check with a tech immediately. If, however, you can’t have an immediate tech visit, then these are the things you can do in the meantime:

Step 1: Remove the SIM and SD cards

Let’s not assume anything else, so for now, let’s think the phone suffered liquid damage and we have to act immediately so as to narrow down collateral damage. That being said, remove your SD card and SIM card immediately as these things can easily be damaged by water. Don’t insert them back until the problem is fixed or until you are 100% sure it’s not water damage that’s causing the problem.

Step 2: Turn it off and bury it in a bucket of rice

Water-damaged phones shouldn’t be turned on while some residue of water hasn’t been dried out yet. However, aside from turning off your device, you should also bury it in a bowl or bucket of rice in a bid to get rid of water residue inside.

Rice is actually a good liquid absorbent and to make sure you get rid of liquid inside your phone, bury the phone for two days and then try to turn it on again and try out all things that were having issues with. If the problem remained, then it’s time to have someone help you out in fixing the problem.

Step 3: Send the phone in for repair

I understand the phone is still turning on and you might still be able to use all other functions and buttons except for those you mentioned. So, at this point, I want you to backup your data and files and then reset your phone so as to prevent your privacy; it’s necessary you wipe off your personal information before you let someone inspect your phone. Here’s how you reset your phone:

  1. Turn off your Samsung Galaxy S7 Edge.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key. NOTE: It doesn’t matter how long you press and hold the Home and Volume Up keys, it won’t affect the phone but by the time you press and hold the Power key, that’s when the phone starts to respond.
  3. When the Samsung Galaxy S7 Edge shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds. NOTE: The “Installing system update” message may show on the screen for several seconds before displaying the Android system recovery menu. This is just the first phase of the entire process.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
  6. Once highlighted, you may press the Power key to select it.
  7. Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
  8. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.

Please tell the technician what really happened especially the “possible damaged by water” part.

Galaxy S7 Edge just shut down on its own and can no longer boot up

Problem: Just bought a Galaxy S7 edge, 5 days ago. It works well but suddenly this morning while browsing the internet, it shut down permanently and cannot boot-up anymore, i tried pressing the power button several times but it’s not responding and the screen is black.

Troubleshooting: Honestly, we don’t really know what you did on your phone before the issue occurs. However, there are several possibilities why your Galaxy S7 Edge is unresponsive and won’t turn on anymore; it could be due to corrupted or damaged file during the  firmware updates, third-party apps, or possibly a defective battery. So, to rule out this problem we recommend troubleshooting procedures below that might help you fix the issue. Here are the steps to follow:

Step 1: Try doing the Forced Reboot procedure

If the issue occurs due to a system crash, a simple reboot of the system can fix the issue. This procedure is equivalent to a battery-pull procedure for devices that has a removable batteries. To do this, just press and hold Volume Down and Power key for 10 seconds until your phone reboots.

If it successfully boots up without an issue, it might be a system glitch but there’s no guarantee that it will permanently resolve the issue but at least you are aware what is causing the problem.

Step 2: Try charging your device, your battery might be empty

If the first procedure failed to power up the device, try charging it for 20-30 minutes to make sure the battery has enough energy to power it up. Observe the device to see if there’s an indication that it is charging. You can also use another charger if there is one available because it might be the charger that has an issue. While it is connected to the charger, try to look at it if the LED indicator is lighting up or if the usual charging icon shows. If so, then the hardware of the phone has no problem.

Step 3: Remove suspected third-party applications

As soon as the device boots up, try to remember if you’ve installed an application before the problem occurs. You can then remove it because that app may be the cause of the issue.  If you can’t remember any app, you can search on it by following this steps: Go to Apps > Settings > Applications > Applications manager > Select the most recent app on the list (you can sort them by date to know the most recent) > Uninstall. After the uninstallation, go back to the main screen.

Step 4: Run The Device in Safe Mode

This procedure is not a solution, we just want to make sure that your device will respond and boot up in diagnostic state using the buttons. These are the combination keys used in case some issues occurs in your device to make sure the device is still usable and responding. Here are the steps how to boot up in Safe mode:

  1. Press and hold the Power key.
  2. As soon as you can see the ‘Samsung Galaxy S7 EDGE’ on the screen, release the Power key and immediately hold the Volume Down key.
  3. Continue holding the Volume Down button until the device finishes rebooting.
  4. You may release it when you can see ‘Safe mode’ in the bottom left corner of the screen.

Step 5: Run In Recovery Mode

The main reason that you have to boot your phone in recovery mode is to check if the device is still responding and able to restore the device before it has issues. In this mode, you will be able to choose either to wipe system cache partition or to master reset your phone. In this case, you need to choose the wipe system cache partition. It won’t erase your important files stored in your device but only remove all temporary files that might cause the issue.

To do so, follow the steps below.

  1. Turn off the phone.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 Edge shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  6. Once highlighted, you may press the Power key to select it.
  7. Now highlight the option ‘Yes’ using the Volume Down key and press the Power button to select it.
  8. Wait until your phone is finished wiping the cache partition. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.

Step 6: A Trip To Your Local Service Center

If all the procedures above are not helping and didn’t resolve the problem, then bring your device to the nearest Samsung service center. Your device might be experiencing a hardware issues that only the professionals are the ones able to resolve the issue.
