Problem #1: Galaxy S6 won’t turn on after leaving the phone charged overnight

Good evening! I purchased my phone Samsung Galaxy S6 edge in Ukraine in February 2016. It worked ok all the time. At 4 of April i put it for a night-long charging as usually, it never turned on again. I tried all kind of troubleshooting that can be found on Youtube and on Android forums (pressing volume/power/home buttons at one, pressing all different combinations of those buttons) nothing helped. It didn’t react on any charger. Dead is dead. I went to the Samsung Service Center in Cairo (I live in Cairo), they told me it’s a problem with motherboard and to fix it will cost me $300, the price of the new phone. Can something be done? Thank you very much in advance! — Olga

Solution: Hi Olga. If a professional has checked your phone and declared that the only way to fix it would be to replace the motherboard, then there’s nothing more that you can do about it. A motherboard replacement is the most drastic solution a technician must do to fix a hardware problem. This means that a number of components may be damaged, or that the board itself is beyond repair.

Problem #2: Water damaged Galaxy S6 showing overheating icon when charging

I dropped my Samsung S6 in water. It was only in for 5 seconds approximately and when i grabbed it, it was working fine.. as in screen was still visible etc.. i immediately put it into a bag of rice but due to being a sealed phone couldn’t remove battery... phone since went flat and now when i try to charge it it gives me the thermometer and overheating warning. It’s been 5 days since and still showing this warning. I’ve checked inside SIM tray and can see a white sticker thing. I’ve called a repair place and they are not to keen on fixing it as they tend to think all water damaged phones are non repairable. I only just got this phone. Please tell me if it can be fixed. — Tania

Solution: Hi Tania. Unlike its successors, the Galaxy S7 and S8, your Galaxy S6 does not enjoy water resistance protection. This means that even just a second of immersing it in water, there’s a very big chance that water can seep into the insides of the device. If your phone was working normally before you dropped it in water, then it might already be too late to do anything at this time. In some cases, dismantling the device right away and removing the battery can save it from permanent damage. We understand you were not able to do this important “first aid” step because a Galaxy S6 has a non-removable battery pack so all you can do right now is to hope that damage is isolated to few components only. A full hardware check is still needed to be conducted though so you must find another service that can do this task for you. Stop whatever you’re doing and stop looking for software solutions. There’s no amount of troubleshooting that you can do on your end to fix a water-damaged phone. Otherwise, simply have it replaced.

Problem #3: Galaxy S6 won’t charge and won’t turn on

Hello! I am experiencing some charging issues with my Samsung S6. The phone shut down with 2 to 3% of battery, just before I arrive home. And then I put it into charger, and started to do my things, without paying attention on it. The problem is, after some minutes I tried to power it on, and it did not work! Nothing! Then I found your guide, and got some “advances”, but without a solution. Here it was what I tried:

  • When I put it into a different charger, the lightning bolt icon appears once, and disappears. The phone doesn’t charge and the charger does not warm up. (Sometimes I’m able to power the phone on, but it shuts down again when the lockscreen appears).
  • I tried to put it into PC USB port. Same as different charger. (With the original charger, NOTHING HAPPENS! Not even the lightning bolt icon).
  • Tried to press Volume Down + Lock while “charging”. The lightning bolt flicks on… (appear/disappear). But it still do not charge.
  • Tried to press Volume Up + lock + home, and the Android management screen appeared. (Installing System Update, and after it appeared an image of the android mascot and a warning icon).
  • Tried the “reboot system” option… reboot, but nothing.
  • Tried V.UP + LOCK + HOME again, and left it there to see if it would charge. I considered to try “Reboot to bootloader” option, but as I don’t know what it means, I thought it was better to contact you.

(PS: This menu only appears with the smartphone plugged into USB port of my computer of with an alternate charger. With the original one, or without a power cord, nothing happens). As I have some really important data that I was about to back up, I’m really against a wipe reset. Any ideas? 🙁 — Tiago

Solution: Hi Tiago. Since you’ve already tried almost everything that can be done on your end, you should really try a factory reset first to see if the cause of the problem is software related or not. If that won’t fix it, the cause of the problem may be bad hardware such as a malfunctioning charging port or battery. Consider sending the phone in for repair.

Unfortunately, file recovery or transfer is only possible if the phone powers on first. If you can’t turn it back on, no external device can access your phone’s internal storage device.

Problem #4: Galaxy S6 edge turns itself off and on

Hi. Recently i have factory reset my Samsung Galaxy S6 edge. Since doing so whenever i open specific apps or randomly the phone switches off and no longer switches on. i will click on the power on button the Samsung sign will show up but then it was fall powerless again. to switch it on again it needs to be plugged into a charger. this happens even if I’ve let the phone charge to 100% or whatever the charge % is. once iv switched it on no matter what the % charge it was on, the charging icon will show a much lower % than it was before it switched off. as soon as i unplug the charge the phone will again switch off and no longer turn on. — Ayishasadiq

Solution: Hi Ayishasadiq. Try recalibrating the battery first and see what happens afterwards. Sometimes, Android can lose track of the actual battery level for some reason so it’s good if you can recalibrate it. Here’s how it’s done:

  1. Use the phone by playing games or doing tasks to hasten power discharge, until the phone turns itself off.
  2. Turn the phone on again and let it turn itself off.
  3. Charge the phone without turning it back on.
  4. Wait until the battery says it fully charged to 100%
  5. Unplug the charger and turn the phone on.
  6. If the phone says it’s not 100% anymore, turn it off, plug the charger back in and wait until 100% charge is reached.
  7. Unplug the charger the turn the phone on again.
  8. Use the phone until you drain the battery down to 0.
  9. Repeat the cycle once.

Once you’ve recalibrated the battery, you can follow it up with a cache partition wipe to ensure the system cache is refreshed. Here’s how to do it:

  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.

Problem #5: How to recover pictures from wet Galaxy S6 edge

Need your immediate and expert advice in seeking a solution on my Samsung S6 Edge phone. Here is what happened:

My phone had accidentally fallen in the swimming pool and all we did was take the phone from the swimming pool, kept it on the table over a towel and began swimming again.

After almost 30 minutes we came back to our room and tried drying it using a blow-dry but it would just not switch on. We tried doing this 3-4 times and then switched off & tried charging the phone as well – with no luck! We then took it to a local repair shop who opened up the entire phone and said the IC wasn’t working and he would try his best – and then later informed us that even the mother board of the phone was spoiled.

By the way, this is still under warranty until the 12th May 2017. Now we need your help with 2 things:

Can this phone be fixed at all? How do we get this started ? How can I retrieve all my pictures? Is there a way?

Looking forward to your kind reply. — VARSHA

Solution: Hi Varsha. If a trained technician who examined your phone said that that power IC or motherboard are toast, that’s like saying the phone is completely dead. A key “first aid” step that you’re supposed to take in an ideal situation would be to immediately remove the power source from the phone to prevent shorting components. We know this is not possible with your S6 as the battery is non-removable so we can assume that a number of core hardware components are fried. So, in terms of a fix, we don’t think there’s anything that can be done at this point.

Retrieving files is obviously out of the question because you need to have a good working system to access the internal storage device. The Nand chip must be powered so an external device like a computer can reach the files. The touchscreen needs to be working as well so you can input commands to the operating system.

Unfortunate as this is for you, we’re almost certain that your phone is dead, especially that the power IC had been confirmed to be toast.

Problem #6: Galaxy S6 drains battery fast, won’t turn on

Hello. Recently my phone’s battery has been depleted much more quickly than normal. I didn’t think much of this, just thought that it was part of the designed obsolescence because I’ve had it about a year and a half now. Today, however, when I went to charge it, it would show the charging icon as normal, and the red light would appear in the upper left hand corner, but when I went to check it the battery percentage had decreased, not increased. It still showed that it was charging. Then, later, I noticed that it kept switching back and forth between charging and not charging. I am not sure if this was an issue regarding my handling of it at the time or not. I tried plugging it into a computer via USB, thinking the wall adapter may be to blame. Everything behaved as normal when I plugged the phone in the computer. The computer recognized it and my phone asked if it wanted me to allow the computer to access it. Again it gave the charging signal but it died soon after. When I got home I plugged it into my charger at home (the original charger) and I initially saw the red light, but have not since. It has been plugged in for about two hours now and it will not turn on. I’m sorry, I don’t know the version I have, so I just put other. I would check it on the phone but it’s dead. Any help with this would be greatly appreciated. Thank you. — Jeremy

Solution: Hi Jeremy. There’s a chance that the problem is only isolated to the battery so if you’ve already tried different chargers before contacting us, you should consider sending it in for repair. Android troubleshooting is mostly software in nature but since the phone does not even turn at all, there’s nothing much that you can do. If you haven’t tried it though, you can also check if your phone will boot to alternate modes so you can then perform follow up troubleshooting.

Below are the steps that you can do:

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.

Problem #7: Galaxy S6 screen stays black but won’t turn back on

While trying to start up the phone, all it does is play the start up music over and over and sometimes it cuts the sound off like it won’t start up all the way. It doesn’t vibrate and the screen remains black. I’ve tried all the other sequence of buttons to push but nothing is working. When it’s trying to start up there is a steady blue light showing and when I push the up volume and power button I think it shuts off because the blue light will go off. When I plug it in to charge the little light is orange then it turns green, but screen still remains black. I do not know what android version it is. — Toni

Solution: Hi Toni. Your phone actually still turns back on so the issue must lie with the screen only. If you dropped the phone or got it wet before, stop wasting time in looking for software solutions. Contact Samsung, your carrier, or any relevant party so it can be repaired or replaced.

Problem #8: Galaxy S6 edge screen keeps flickering after it got wet

Hi. My Samsung S6 edge fell in the sink while water was running and I thought it was a small amount of water entered my phone. My phone went blank (black screen) so I was not sure if it was off or on. So I then took out my sim card tray and left my phone in rice for the day. I took it by my friend after work for him to have a look at it and when he opened it I saw part of the inside was corroded so he clean the board and stuff. However about 3-5 of the ICs (as he called it) were missing from the board near the sim card section, but he was not sure what they were for. He evened changed the battery for me. Everything was working fine as if nothing happened. But the only problem is that my phone battery runs down veryyyy quick and my screen keeps flickering while charging so I am not sure what to do now. Is it possible my phone can still be saved? Thank you in advance for all the help! Many Thanks. — Kerri
