Problem #1: Wet Galaxy S6 won’t turn off

I dropped my Samsung S6 in a sink full of water today unfortunately. It didn’t power off and continued to play Pandora. I attempted to power off and dry everything off as quick as i could. I am currently at work and there is no rice for me to put it in. Do  you have any suggestions because the buttons on the screen aren’t allowing me to select anything such as the “power off.” — Kasandra9021

Solution: Hi Kasandra9021. A Galaxy S6 is not water resistant like the Galaxy S7 and S8 so if you are now experiencing problems after it got wet, you should assume there’s an on-going hardware malfunction. In an ideal situation, you are supposed to do the following after exposing your phone to water:

  1. turn off the phone,
  2. remove the battery,
  3. dismantle the internal assemblies such as the motherboard, etc.,
  4. clean the disassembled parts with alcohol (not the drinking type), and
  5. dry the parts for several days inside a sealed bag of rice.

We understand you can’t do the steps above because the battery pack is non-removable and the phone itself is difficult to open. It’s for this same reason that we recommend that you send the phone in to Samsung or to an independent service center so the hardware can be checked and the steps above performed. Keep in mind that said steps are considered “first aid” procedures only. They are meant to minimize damage to the hardware but repair or parts replacement may still need to be performed, especially if the initial water contact immediately resulted to permanent damage.

Problem #2: Galaxy S6 stopped charging, won’t charge anymore

My husband plugged in his Galaxy to charge it. It then shut off randomly then came back on with a blue downloading screen, it started to charge but not fast charge then stopped all together. i plugged in my s7 it said moisture detected and i unplugged my phone from it. we then used a blow dryer on his even though it did not say there was any moisture, thinking that was the problem with the charger, we tried multiple chargers. now it’s not charging at all. — Leahf5588

Solution: Hi Leahf5588. If your husband’s phone is not charging now but is still turning on, try doing a factory reset and see if that will fix it. Factory reset should address any software bug that may be causing this problem. Here’s how it’s done:

  1. Create a backup of your important files such as photos, videos, contacts etc. You can use Smart Switch for this task.
  2. Turn off your Samsung Galaxy S6.
  3. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  4. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  5. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  6. Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
  7. Once highlighted, you may press the Power key to select it.
  8. Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
  9. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  10. The phone will now reboot longer than usual.

If the phone continues to fail to charge after a factory reset, find a way to have its hardware checked.

Problem #3: Galaxy S6 SMS won’t send, overheating, and draining battery fast

My messages won’t send. they send for a couple minutes then fail. I have to restart my phone and try again. Took it to Best Buy to get it flashed and they couldn’t because “manufacturer and binary code didn’t match,” whatever that means. It also is getting super hot and draining battery by the second when it does this. In the past it has done this shortly after a new update has come out and updating has fixed. — Chelsea

Solution: Hi Chelsea. We don’t know anything about your phone’s history so we have no idea what is causing the problem. If we can’t identify the cause, then there’s we can’t give the best advice for you. We often receive pleas for help from our readers with a similar situation (but not giving us any helpful information leading to the problem) so our suggestion for you is to do the basic software troubleshooting such as:

  • cache partition wipe,
  • observing in safe mode,
  • Installing app updates, and
  • factory reset (steps provided above).

If nothing will improve the situation at all, you then have to send the phone to your carrier, Samsung, or to any relevant party that can help check the hardware or replace the unit.

For reference, below are the steps on how to do the steps mentioned above.

How to wipe the cache partition

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

How to boot an S6 to safe mode

  1. Press and hold the Volume Down and Power keys for 20 to 30 seconds.
  2. Once you see the Samsung logo, release the Power key immediately but continue pressing the Volume Down key.
  3. Your phone should continue booting up and you will be prompted to unlock your phone as usual.
  4. You will know if the phone successfully booted in safe mode if the text “Safe mode” is displayed at the lower-left corner of the screen.

Problem #4: Galaxy S6 edge screen stays black, won’t turn on

Greetings. My Samsung S6 edge stopped working and I tried every trick out there. One afternoon I placed my phone aside and when I came back to it it was blinking blue. I assumed I had a message so when I tried to turn on the screen nothing happened. I knew for a fact that it was charged and the since It was blinking I thought it was on so I searched up what to do in this case. I did what they asked and nothing happened. After a while the blinking stopped all together and still my phone won’t turn on. I charged it with wireless, the computer, and with fast charger, but still it would not work. I used up most of the storage of the phone so I’m guess that might be a factor of why it stopped. Please help for I know not what to do. Thank you so much. — Abbie

Solution: Hi Abbie. Unfortunately, there’s very little that we can do if the phone is completely dead at this time. If it doesn’t show any signs that it’s on at this time, there’s most probably a bad hardware somewhere causing it. The only thing that we can suggest for you is to try and see if you can turn the phone to alternate modes. If it will power on to, say, Recovery mode, then you may be able to fix it by doing a factory reset. Here are the steps on how to boot your S6 to different modes:

Boot in Recovery mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 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. You can either wipe the cache partition or do a factory reset when in this mode.

Boot in Download Mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume DOWN keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume DOWN keys.
  4. Wait until the Download screen appears.
  5. If you can boot the phone in download mode but not in other modes, that means that your only way out may be to flash a stock or custom firmware.
  6. Use Google to look for a guide on how to do it.

Boot in safe mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and hold the Power button.
  3. Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
  4. Continue holding the button until the phone finishes rebooting.
  5. Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
  6. The only difference of safe mode from normal mode is that the former prevents third party apps from running. If you can boot the phone in safe mode but not in normal mode, uninstall all apps until the issue (that prevents you from booting normally) is eliminated.

Remember, if your phone stays dead or won’t respond to any of the hardware button combinations above, you have to send it in for repair.

Problem #5: Galaxy S6 Phone app not working properly, phone numbers are shown in different format during calls| Galaxy S6 SIM card error during calls

I’ve been having several issues with the “Phone” app. I’m using a Galaxy S6 with Straight Talk, though the phone was originally from Verizon.

1) When receiving a call, the displayed number is shown in a weird format, as if it were an international call. For example: 12 34 546 890 instead of 123 456 7890.

2) When I try to call companies with automated machines answering, like my bank, the machine can’t seem to understand what number I press. Example: “Please enter the last four digits of your social security code.” 1234. “Please enter the last four digits…”. But when I try on a different phone, it works perfectly.

3) Sometimes my calls will cut out in the middle with the message: No SIM or SIM Error.

4) People complain I’m very quiet on the call, despite my microphone working fine for other applications. — A03.mia

Solution: Hi A03.mia. Every network usually modifies vanilla Android developed by Google to cater to their own needs. This means a Samsung device of the same model from two different carriers will have two different firmware versions and apps.  Using a Verizon phone in another network like Straight Talk will not necessarily mean all the pre-installed apps like the phone app will work as expected. Right now, the firmware that’s running in your phone is still basically that of Verizon and this may be the reason why you have a number of concerns. Your Verizon phone may be unlocked, which means its network function has been modified to allow it to work in a non-Verizon system, but basically, a lot of Verizon stuff are still running (or not running), which may be causing all your problems.

Sadly, we are not aware of any modifications that can address all or some of your issues. Code changes may be able to address some problems you mention here but we are not aware of anyone who published an alternate firmware that you can flash to fix them. Try to visit other Android forums (like XDA Developers) that hosts active modders to see if they can give you a good firmware to install to remove Verizon restrictions or address the problems you’re having.

Problem #6: Galaxy S6 won’t reboot randomly when connected to a charger

We have a Galaxy S6 and have had trouble with the phone constantly restarting. We have done some research and seen the ‘on/off’ button being defective and forcing the phone to restart constantly. I would believe this to be the case with my phone as well except for the fact that the phone works fine when plugged into a power source (a laptop). The phone was not reliant on a wifi network source and worked for a few minutes once, but otherwise restarts randomly. Please let me know what we can do if there is a reason why the battery seems to be failing or the power switch could cause an issue like this. Thank you. —  Tom

Solution: Hi Tom. If the phone works normally and does not reboot on its own when it’s connected to a charger, then a bad battery is possibly dying at this time. Since you can’t just take out the battery and replace it, we suggest that you let Samsung or an independent service center replace it for you.

Problem #7: Galaxy S6 can’t answer calls when using another SIM card

I have a Samsung Galaxy S6 and the issue is when I have an incoming call. I try to answer the call and when I drag the green button to answer the call, suddenly Miss call happens and I could not answer the call. And I should tell you one more thing that if I change the SIM card to a special telecommunication company that is called Roshan telecommunication company in Afghanistan, then it works properly. I mean I can receive any calls and the phone works properly but if I change the SIM card to other companies, then I’m unable to receive any calls. I guess Roshan company has done something with the phone and this is what inside the Android system. — Reza

Solution: Hi Reza. Good observation. If Roshan Telecommunication is your carrier, then you should work with their technical support team to fix a possible incompatibility issue. In case Roshan Telecommunication is not your carrier, you still want to talk to your carrier about it so they can tell you if your phone is properly configured to work with other networks.

As far as device troubleshooting are concerned, you are limited to doing the basic stuff like wiping the cache partition (steps provided above), clearing the Phone app’s cache and data, and factory reset (steps provided above).

To clear your phone’s Phone app, follow these steps:

  1. Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  2. Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6 or 7.
  3. Once in there, click on an application.
  4. 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.
  5. You should now clearly see the Clear Data and Clear Cache buttons for the application.

Problem #8: Galaxy S6 wifi won’t turn on

Hi. My wifi will not turn on for my Samsung Galaxy S6. Every time I press the wifi button, it stays a light green color like when it’s about to turn on. I turned the device off and held the power button until Samsung Galaxy S6 appeared in screen, then I let go of power button, directly pressed and held the volume down button until I saw safe mode. And I tried again. And still the same problem. So i know it’s none of my applications or anything. It has to be the phone or something.

I really don’t wanna throw this phone away. It’s in really good condition. It’s my roommate’s — basically my brother’s phone who recently passed away. And I’d like to be able to use it because i currently have a Samsung Galaxy J7. But if you could please possibly help me. Maybe it’s the wifi antenna on the inside loose or something.. please and thank you. Your time is greatly appreciated! — JT

Solution: Hi JT. Do a factory reset and proceed from there. If wifi stays unresponsive after you return all software settings to a clean slate, then you can assume that hardware malfunction is to blame and you will have to send it to a service center to be fixed.

Problem #9: Galaxy S6 screen flashes yellow and stays black, overheating, and charging port not working

Hi. I hope you will be able to make sense of this explanation! I have a Samsung S6 purchased brand new just over 1.5 years ago. For the last month, whenever I try to open the phone using either the power button or home screen button, I get major flickering on the screen. The whole screen, and sometimes just part of it, will flash yellow and then go black. This will happen several times and I will eventually force it to turn off by pressing volume button and power button together. It will work for a bit and then same issue again. It has been getting worse over the last few days. I also think there may be an issue with the charger port as the charger isn’t slotting in well and keeps slipping out. Please help!! Regards. — Anjum Ps i don’t know what version im running. — Anjum

Solution: Hi Anjum. The symptoms you mention here all points to bad hardware. Do a factory reset to check if it’s being caused by a software bug (we doubt it). The problem reappears after a factory reset and without the third party apps, have the phone repaired or replaced.

If your device was physically impacted or damaged before, skip the factory reset and go directly with repair. You can’t fix a hardware issue by doing some software hacks.
