Problem #1: Fix to Galaxy S6 Edge Plus boot issues

Hello, I have an S6 Edge Plus. I have had it for a while now for a few time now. I have been taking good care of it — no water spills, falls etc. I live in the United States, but I came on vacation to Mexico for a couple of months. While in the United States my phone froze a couple of times about 5 to be more precise. I don’t remember exactly when I do a software update to the phone but it was pretty close to when the phone started freezing.

I remember the first 2 times it froze I was playing with an app that takes up a lot of battery (Mortal Kombat X). I have been playing this game for a while now with no problem on the Note 4 and on the S6 Edge before the upgrade. The other 2 times it froze I was just using the internet, and the last time again Mortal Kombat X.

I didn’t pay much attention to the problem because the problem was fixed with the soft reset. One thing that I noticed though was that every time I powered the phone up after any reset occasional reset of battery draining, the phone always started with displaying phone updating and after phone successfully updated on occasions during the display of the phone updating the phone heated up. But again it worked fine.

Days after arriving to Mexico my phone froze and didn’t respond at all — no buttons were working. I couldn’t do any type of reset until the battery drain. The first time I charged the phone and it charged and worked normally for about 2 days. When again the phone froze and the battery drained, again the phone charged but this time it just powered up to heat up. Without using any apps I tried to soft reset and the phone didn’t turn on this time. It didn’t even charge.

I left the phone connected to the charger for hours — no response at all, no LED light nothing. I unplugged and set it aside for 2 days then I plugged it in and I started charging again. I turned it on again — it worked for about an hour but again it got very hot. And again I tried soft reset and the phone went dead without response at all, not charging again.

Then in my desperation, I took of the back of the phone displaying the back part and part of the battery of the phone and just left it like that. After a day, the phone started working again. this time it worked for about one day with the no-back portion, then again heated up. This time I didn’t do any soft reset since the phone didn’t turned back on but still it drain the battery without any response while still on and then it died. This time it lasted about 3 weeks. I plugged original Samsung chargers since I bought a few. My wife and my son have both Note 5 and I also tried their wireless chargers and nothing. I tried leaving it on the charger for hours and nothing.

A day ago I tried again and “miracle” it was charging. I let it charge up and then turned it on. It worked fine after weeks, It worked for about 2 hours but I tried using the apps and it got hot it started heating up in the camera portion but close to the power button. It was really hot as well as the front of the phone where the camera is located. It also started making a loud noise that others may not hear because the back of my phone is off. A noise like a small fan or something turning real fast close to the power button. Then the phone froze and it again until the battery drained I though it wasn’t going to charge again so I left it aside.

But a few hours ago I tried charging it, and the phone charged. I turned up now it’s been working for hours. But I tried using the any apps not necessarily the large ones but small one and the phone starts heating up fast. this time since I had already noticed it I turned them off fast and lay the phone down on cold concrete to cool it down. I did it to see what apps where heating it up and apparently it’s all. But I remembered that on these occasions when the phone froze for days, sometimes I wasn’t even using any apps at all. One time it overheated when the phone was displaying phone updating like I mention it always displays this when turning the phone on.

Any suggestions please chargers are working properly and are the original S6 Edge plus charger and Note 5 chargers. — Martin

Solution: Hi Martin. An Android device, and in fact any electronic device for this matter, can randomly reboot or fail to boot up normally due to one out of a variety of possible causes. In your case, we think that the main problem has something to do with a bad hardware component, possibly a malfunctioning processor or camera (thus the fan-like noise you heard). Smartphone technology doesn’t use active cooling like what you see in computers (where processors have their own fan/s) so any spike in internal temperature when a processor suddenly stops working normally can cause the phone to shut down on its own. This automatic shut down feature is mechanism that’s designed to prevent damaging the device due to overheating. You must allow the phone to cool off for at least 2 hours before attempting another reboot. It’s still interesting to note though that you won’t be able to power on the phone for days after this. This means that there may be other reasons why your phone prevents boot up. It may be that other hardware components are not working properly as well, thus a full hardware diagnostics must be conducted. Keep in mind that no software glitch will prevent you from turning on the phone for days. Only a hardware problem can cause a problem you’re experiencing right now.

Since a thorough physical check is necessary before a resolution (if there’s any) can be determined, we recommend that you let Samsung technicians do the checks. Better still, simply ask for a replacement phone to ensure that you have a good working device.

Problem #2: Bricked Galaxy S6 from eBay won’t turn on

I bought this phone on eBay because the vendor said he was told it was bricked. Looking online, I saw that there are several ways to unbrick a phone by using Kies or Odin (Jodin because I have a Mac). For these fixes, however, it is necessary to initialize download mode. The vendor said his phone would shutdown for no apparent reason and it increased in frequency until the phone no longer powered on. I now have the phone and I fear there is more wrong with it than being bricked. Currently the phone will not power on and is completely dead. I have tried the V-down/Power trick, the V-down, Power, Home trick, the V-up, power, home trick but nothing works. Thinking that the battery might be dead, I decided to plug the phone into the charger and try the tricks again. I had to use the charger from my Tab S for this since the phone charger did not come with the phone. After plugging in the phone, the charging icon did not show. I then decided to try plugging it into my computer but still no charging icon. I even tried 3 cables but nothing. This is leading me to think that there is a problem with the charging port or worse. Before I take it in to a technician, do you have any suggestions? Thanks. — Mark

Solution: Hi Mark. We don’t know your expectations but you’ve already tried all the things that we can suggest in a case like this so going through the technician route should be a wise choice for you.

Problem #3: Galaxy S6 can’t boot to Recovery mode | Galaxy S6 won’t boot normally

Hi, I have this issue with the Samsung S6 SM-G920F. I was wondering if you can help me with it. Previously when I plugged it in, it would get stuck with the battery icon with lightning bolt. when I plug it in to charge the battery, the back gets really warm but the light never turns on on the upper left corner saying it’s charging.

I tried to do a factory reset using the Power, Volume Up, and Home buttons but it would not do it. I ended up flashing the latest Samsung S6 SM-G920F factory firmware using Odin. Now when I turn on the phone while plugged in, it would get stuck on the Android logo screen and when I charge the phone the back still gets very warm but the upper left light still does not come on?

The phone seems to take a little bit of a charge when I plug it in for 20 minutes but I can’t turn it off. It eventually turns off, I’m assuming because the battery drains to nothing. Do you have any idea what’s wrong with the phone and what I need to do to repair it? Thanks for your time and assistance. — Eddie

Solution: Hi Eddie. The only thing that we can say is you need to find a way to have the phone checked for possible hardware failure. An issue like this can just as easily be the result of a bad software/bootloader or a malfunctioning hardware. That you can’t boot it in recovery mode appears to suggest that the bootloader is no longer working properly. To put it simply, a bootloader is a code or series of codes that must be executed before Android operating system runs. In other words, it’s a special code that instructs the operating system to run normally. It’s a different software environment independent of the operating system and usually encounters problems after a user attempts to modify it. If you’ve attempted to unlock your phone’s bootloader before the issue occurred, you only have yourself to blame. There’s always an inherent risk that complications can happen if you tinker with an official software (which is why manufacturers don’t officially support unlocked bootloaders). As far as solutions to corrupted bootloaders are concerned, we are not aware of any (that’s freely available for public consumption anyway) so your only route right now is to look for a way to have the phone replaced.

If you never did attempt to modify your phone’s official software via rooting or flashing before the problem started to happen, you can assume that there may be an unknown hardware problem causing it. Since the only way to figure out a hardware issue is by thorough diagnostics, make sure that you submit your phone for repair.

Problem #4: Galaxy S6 Edge fast charging stops working | Battery drain issue on Galaxy S6 | Light on Back button of Galaxy S6 Edge keeps flickering

Hi. I have a Samsung S6 Edge and got it last October 2015.

BATTERY. My battery life is not lasting for long anymore and usually takes overnight (6 hours) to fully charge from 3% to 100%. Fast charge used to work, but just completely stopped 2 weeks ago so can only cable charge now. (I still have the original Samsung charger, but have changed the lead as I thought the lead was the reason it was no longer fast charging, it has been shoved in my bag far too often).

LIGHTS. When using my phone such as reading an article on the news or something, the lights at the bottom keep flickering without being touched (that are for the ‘return’ button or for seeing all open pages). This happens even if I have just one single page open. I have restarted multiple times, deleted lots of photos/storage hoggers, cleared all cache bits and scanned it multiple times as well as installing Clean Master to help monitor things. I’m not sure if this could be sent back as faulty for being under 12 month warranty? Or is there something I can do instead. Thanks in advance, please keep answers simple as I’m not technically minded! — Stephanie

Solution: Hi Stephanie. You may benefit from doing basic software troubleshooting first. We suggest that you try booting your S6 in safe mode to see if a third party application or associated service is to blame. Here’s how:

  • Press and hold the Volume Down and Power keys for 20 to 30 seconds.
  • Once you see the Samsung logo, release the Power key immediately but continue pressing the Volume Down key.
  • Your phone should continue booting up and you will be prompted to unlock your phone as usual.
  • 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.

Remember, if the issues you mention here won’t occur while your phone is in safe mode, that’s an indication that one of your apps is the culprit. Since safe mode won’t point you which of the app is the cause, you must manually remove each one until the is eliminated.

If the same problems happen even while your S6 is in safe mode, the next logical step is to do a factory reset. Ensure that you create a backup of your personal data first before you do this step. Follow the steps below on how to do a master reset on your S6:

  • 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 Volume 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.

Finally, if nothing appears to change right after you do a factory reset (and no apps installed), that’s a sign that you have a bad hardware. Call Samsung, describe your issue, and demand for a new device.
