Problem #1: Galaxy S6 screen stops working due to water damage

i was making a call on my Samsung S6 and suddenly the screen started flickering madly until such a time as the screen went dead. i could hear messages coming in and phone calls coming in but i could not see anything on the screen as it was looking like as if it were completely off. i handed my phone in under warranty as it is only 2 months old and they sent it away. when it came back they said it had water damage even though i haven’t had it near water and been very careful and that they could do nothing with it and the warranty wouldn’t cover water damage. I’m extremely frustrated by this because it has not been near water and surely not corroded within 2 months. I’d love to know is there anything i can do with this if anything? — Sean

Solution: Hi Sean. If the attending service center confirmed that the device is water damaged (probably after checking the Liquid Damage Indicator located under the SIM card tray slot) and they won’t fix the device, then it’s up to you to it repaired. Our blog does not provide hardware troubleshooting and guides in replacing hardware components. Bring the phone to a third party shop and see if they can replace the screen assembly. Depending on the damage, screen replacement may or may not fix the issue entirely.

Problem #2: Galaxy S6 screen not working and phone won’t turn on after falling

My wife’s Galaxy S6 felt on the floor and the screen immediately becomes black, even though it rings, receive messages and LEDs keep blinks. We tried to plug at our PC to backup our archives, but the phone was locked and we had no success doing that. So while we were trying other way to do that we ended up putting it at “download mode”. At some point its battery completely dry out and after that the phone don’t turn on anymore and is not charging via TA/USB port too (yet, we intend to try wirelessly charge it but we do not have this type of charger)! So how could we restore our archives in this situation!? Any ideas? Is it possible that crash cause a broken screen and a power issue? Thanks. — Conrado

Solution: Hi Conrado. Dropping any electronic device may or may not result to significant hardware damage. If you’re lucky and no signs of abnormal behavior is observed immediately (or later) after a drop, then that device will probably survive without any problems. However, if you encounter severe issues right afterwards, then the device is obviously suffering from hardware malfunction. While hardware manufacturers like Samsung take into consideration the fact that their devices will most probably take some tumbles during their lifetime, the current crop of smartphones are not 100% resistant to ill-effects of a bad drop. If your wife’s phone no longer show a working screen or doesn’t even turn on, then the device is most probably toast at this time.

So how could we restore our archives in this situation!? This depends on whether the memory is still intact and working, and of course if you can make the phone power on in the first place. The only way to access your files is to make sure that the phone works, that means it still powers on and you can still access the software that will provide access to the memory. If you will be able to power on the phone but the screen remains unresponsive, you may still be unable to move your files because you still need to enable transfer mode. In a word, turning on the phone may not be enough if your primary end is to create a copy of your files stored in the device; you have to make sure that the screen is also working.

That said, try to call Samsung or your carrier to see if they can fix the device for a fee. You will definitely have to pay for whatever repair is needed since carriers and hardware makers will automatically void the warranty in this case. If you can’t access Samsung service center or your carrier, bring the device to a good service center.

Problem #3: Galaxy S6 cannot receive SMS and MMS from newly added contacts

I recently bought a Samsung Galaxy S6 through T-Mobile, and I’ve been having an issue with the SMS. When I bought the phone, I had my contacts and information transferred to the new phone through Samsung Smart Switch, and everything worked fine. However, when I tried to add new contacts to my phone, I began encountering issues. Any new contact that I have added after receiving the phone, I am unable to send or receive SMS or MMS messages from. My third party SMS application simply crashes when I try, and the default Samsung SMS app sends whatever I tried to send into a seemingly random previous group conversation. The phone is running on android 6.0.1 Marshmallow. I attempted to start the phone in safe mode, and encountered the same issue, implying it is a problem with the operating system and not with any third-party application. — Kaylee

Solution: Hi Kaylee. The first thing you want to do here is to wipe the cache and data of contacts and SMS apps. Sometimes, imported files from a another application can corrupt the cache and data of contacts app which may result to the issue you’re having. Clearing the cache and data of the contacts and SMS app can fix the issue. Here’s how to delete an app’s cache and data:

  • Go to Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  • Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6.0.
  • Once in there, look for the Contacts app and tap it (same thing for whatever SMS app you’re using later).
  • You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
  • You should now clearly see the Clear Data and Clear Cache buttons for the application.

Also, make sure that you wipe the phone’s cache partition afterwards just in case this cache is also corrupted. This procedure is recommended whether or not your phone has issues so it’s safe to do. Here’s how to do it:

  • Turn off the device.
  • Press and hold the following three buttons at the same time: Volume Up key, Home key, and Power key.
  • When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
  • When the Android System Recovery screen appears, release the Volume Up and Home keys.
  • Press the Volume Down key to highlight ‘wipe cache partition.’
  • Press the Power key to select.
  • When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
  • Press the Power key to restart the device.

Problem #4: Galaxy S6 multi window is stuck | Galaxy S6 back button light is not working due to water damage

Hi. My name is Katie. I am reaching out because I have a Samsung S6 and it has a little water damage. It was not submerged into but got a little wet from being on a boat. The phone turns on but the multi window was stuck. It was constantly running in the background. The back button light up too but does not work. I did a factory reset (holding power, volume up and home screen). I was able to reset it but when I turn the phone on the multi window and back button no longer lights up. I can’t afford to do another claim because I’ve already done one. 5 days into having my replacement it gets wet. I am not sure if anything can be done to fix my phone. Any suggestions will help. Thank you. — Katie

Solution: Hi Katie. You can’t resolve a hardware issue with software solutions. Doing things like factory reset will not fix whatever component has been damaged by water. Bring the phone to a repair shop and have it cleaned and dried. If you’re lucky, the hardware may be able to survive long enough for you to save and eventually replace this phone.

Problem #5: Galaxy S6 music app stops playing when screen is locked

Hi. I’ve updated the music app and since then there is a problem that keeps getting worse. At first the problem was that if I locked my screen the music would stop automatically. When I would unlock the screen it won’t show that the music app is running, it would be as if i had closed and stopped it. The only way to have the music playing and the screen locked was to start by keeping the music app working in the background and keeping the screen unlocked. After a few days the problem became worse. Even when I succeeded in having the screen locked and the music playing the music would stop automatically after each song and again when I unlocked the screen it didn’t appear as if the music app was running at all. I had to reopen the app in order to start playing the music again. I would very much appreciate your answer. Thank you. — Ayala

Solution: Hi Ayala. First of all, if this issue started right after updating whatever music app you’re using, then it’s logical for you to uninstall the update. To do that, follow these steps:

  • Go to Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  • Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6.0.
  • Once in there, look for the Music app and tap it.
  • Look for uninstall update button and tap it.
  • Restart the phone.
  • Check if the issue remains.

Now, if the problem stays after uninstalling the app update, do a factory reset and run the music app without installing other apps. If the issue won’t occur, that’s a sign that a third party app may be interfering with the music app’s functions. Do a trial-and-error method of identifying the bad app by installing apps individually then observing how the music app behaves. This will take time but it’s the only way to isolate the cause. To factory reset your device, follow these steps:

  • Create a backup of your important files.
  • Turn off your Samsung Galaxy S6 Edge.
  • Press and hold the Volume Up, Home and Power keys together.
  • When the device powers on and displays ‘Power on logo’, release all keys and the Android icon will appear on the screen.
  • Wait until the Android Recovery Screen appears after about 30 seconds.
  • Using the Volume Down key, highlight the option, ‘wipe data/factory reset’ and press the Power key to select it.
  • Press the Vol Down button again until the option ‘Yes — delete all user data’ is highlighted and then press the Power key to select it.
  • After the reset is complete, highlight ‘Reboot system now’ and hit the Power key to restart the phone.

Now, if the issue remains even after restoring the software settings to default, contact the developer of the said app for resolution.

Problem #6: Galaxy S6 slow browsing issue when using Wi-Fi

I use my Samsung Galaxy S6 EXCLUSIVELY on Wi-Fi to web browse and while my phone is unlocked (not locked to any network provider (it does contain a SIM card which is a pay as you go SIM card, but I haven’t yet put any credit on it)) my problem is that it either won’t display some web pages I go to or does so painfully slowly. Turning my phone off and on again solves the problem, until the next time that is! I know this is a problem with my Galaxy S6 because it DOESN’T happen on my Google Nexus 7 or Samsung Galaxy S2! This problem exists on all browsers on my S6 (Chrome, Opera, Firefox) and even after I did a HARD RESET! I have updated my browsers to the latest versions via Play Store. I did get a Samsung specific PHONE software update a few months ago but to NO avail! — Toptrumps61

Solution: Hi Toptrumps61. Because the slow browsing issue happens on all browsers, this may be a function of your phone’s Wi-Fi functionality. This can be due to a bad Wi-Fi chip or a software glitch. If you’re already tried to factory reset the device before contacting us, then there’s a chance that the phone is unable to load web pages normally due to malfunctioning Wi-Fi system on your phone. Most of the time, this issue can be resolved by installing an Android update, assuming you did not modify your phone’s official software in any way (if you did, you’re on your own). Since you’ve also already installed an update, we think something’s wrong with your phone’s Wi-Fi. Contact Samsung for potential repair or replacement.
