Hello Android fans! The Samsung #GalaxyS6, released over 2 years ago, it’s only normal that majority of issues we received from S6 users are power-related. If Lithium-ion battery performance is to be taken as reference, majority of early S6 adapters should already be having significant battery issues at this time. We hope you’ll find this article helpful.
If you are looking for solutions to your own #Android issue, you can contact us by using the link provided at the bottom of this page.
When describing your issue, please be as detailed as possible so we can easily pinpoint a relevant solution. If you can, kindly include the exact error messages you are getting to give us an idea where to start. If you have already tried some troubleshooting steps before emailing us, make sure to mention them so we can skip them in our answers.
Problem 1: Galaxy S6 won’t boot up, won’t turn off
Hi. I’m kind of in a same situation as Rachel from Problem #4 in the list. My phone won’t turn on for some reason. It was fine this morning when I used it and the last time it was active was when I had my Firefox app to read. But now it’s not responding to the power button when I click / hold it. I followed the instructions you gave to Rachel and Mohammad, but couldn’t get it to turn on regardless. As of right now, I’m hoping to wait out for my phone to run out of battery so it would shut off on its own since I feel a slight warmth from the battery. Is there any other solution to try before I bring it to customer service for repair / replace battery? Please email me back as soon as you can and thank you for reading this. – Khoa P.S. I do not know the type of Android Version my phone have. — Khoa
Solution: Hi Khoa. There’s only so much that you can do when it comes to an issue like this and in fixing Android problems in general. If you’ve already tried the basic troubleshooting such as:
- use a different charging cable and adapter,
- charge the phone for at least 30 minutes before turning it back on,
- try another power outlet,
- inspect the charging port for dirt, lint, or observable damage inside,
- try to check the screen,
- or attempt to boot the phone to alternate modes (Recovery Mode and Download Mode)
without any positive result, then you clearly have a bad hardware at hand. We don’t have enough history of your device to be able to tell you what the problem might be but it must be something hardware-related. In this regard, you’ll need an expert opinion of a technician who can physically check the phone. We just can’t speculate our way in and tell you that the power management IC or battery is busted, for example.
If your phone is still covered by a warranty (probably not), make sure to use it to get free check up and repair. If there’s no warranty on this phone, we still highly recommend that you bring it to Samsung so you’ll know that a qualified technician performs the repair.
Problem 2: Galaxy S6 Recent and Back buttons keep blinking, battery drains fast
Good Afternoon, I am having issues with my phone due to all of a sudden the hyper links at the bottom that look like a U-turn arrow & the index cards that take me to close apps are just tweaking & blinking constantly. And now have my battery is just draining as if all the apps are opened. It is not giving me a way to actually close all my apps now & is sucking the battery so fast.
I have already tried clearing the cache & also doing the factory reboot & it is still doing the same thing. I hope you will be able to shed some light on the issue & Thank You in advance! — Pandra Martin
Solution: Hi Pandra. Both soft keys — Recent and Back (the one that looks like a u-turn sign) buttons — are located at the bottom part of the phone so if there’s damage in this region, they’ll most likely act up together with other components like the charging port and the battery. If a factory reset did not fix the problems at all, you can bet bad hardware is to blame. If you dropped your phone or got it wet before these issues started to occur, let a professional check the hardware. Factory reset is the most that you can do in this case. Unless you know how to perform hardware repair in an S6, you’re better off sending it in to let a technician do the repair.
The fast battery drain issue you’re having may also be related to the reason why Recent and Back buttons may not be working properly. If not, then our suggestions in this link may help.
Problem 3: Data recovery from Galaxy S6 that won’t boot up
Phone will not power on without being plugged-in. When plugged-in, the phone first shows a dead-battery, then immediately shows a charged battery (up to where it left off, i.e. 98%). If left plugged in, the phone indicates that it is charging and keeps going up. I can charge it via USB or wall and same result. I’ve used various cables. When I turn on the phone (while plugged-in), it will boot and startup for various amounts of time from ~10-60 seconds before it blanks off (as if the battery was pulled) and then restarts with the Samsung startup. Booting into Safe Mode produces the same effect. I’d like to backup the phone, but it is not on long enough to do so. I’ve turned off WiFi, turned on Airplane mode, taken out the SIM card and all states produce same issue.Â I tried booting into the bootloader (recovery mode) and it stays on that screen (doesn’t automatically shut off) for as long as I let it sit there (could be several minutes). I don’t want to reset the phone since all of my data/pictures are still present. I successfully cleared the cache using the recovery mode, but the problem is still there. I replaced the battery and the problem is still there. Might it be the logic board? Anything else I can try? — Mark B
Solution: Hi Mark. If your phone won’t turn off on its own when in Recovery Mode, then it’s possibly not a board issue. Rather, there must be something in the software that causes the phone to turn itself off. We’ll never know this for sure unless you perform a factory reset or reflash the software back to stock. Since you’ll be unable to recover data unless the phone turns back on normally, you’re left without much choice in this matter. If you think your data is worth a few hundred dollars to recover, consider contacting companies that specialize in data recovery. Given the current state of your device, there may be a hacking tool that we’re not aware of that they can use to prevent your phone from shutting down long enough to extract data from it.
Problem 4: Galaxy S6 Gallery app permissions, screen turns yellow when battery is low
Okay this is my first time writing into this site so bear with me if I break any rules. I have two questions.
My first question would be, I was reading a post about Gallery asking access to your contacts, your location, and your calendar, which is what brought me to the site in the first place. A reader wrote in the same problem and was told that the iOS system or manufacturer that she got her phone from should not ask for the calendar and it must be a mistake on their part. Well I bought mine from Verizon and it asks for the same thing — calendar, location, and contacts. I can understand the example of why it would need the location but I do not understand why it needs contacts and I definitely don’t understand why it needs calendar.
My second issue and it is a big one is that the bottom half of my screen turned yellow and green when it is low on battery or when it’s getting ready to shut off because it’s been idle too long. I have done a soft reset and I have also done a factory hard reset. Which in fact lost all my data but I thought it was being stored up because it said it was being backed up but it was not. Lo and behold it did not fix my problem. I have went to the display and turn the brightness all the way up and that is the only way that it does not show until like I said. the battery runs down or the screen is going to shut off because it’s been idle for too long. — Lori
Solution: Hi Lori. Let’s answer your questions one by one.
Apps are designed to perform tasks and sometimes, these tasks may require access to sensitive account or device information. In Android, apps are required to ask explicit permission from a user to, say, access contacts or storage. These permissions may be necessary in order for an app to work properly or not. For example, Gallery needs access to contacts since some apps that use it, like Camera, has functions that allow a user to send photos in their contacts list. The decision regarding an app asking for certain permissions resides solely on the developer. We can’t give an every reason why a developer would want to access a particular permission. If you have a problem with an app’s permission, you have to redirect your question to the developer and not to a support site like us.
If you think an app is not supposed to access sensitive information, there are two ways to restrict permissions — by turning off permissions during installation, and checking permissions of an installed app.
Check permissions before or during app installation
- Open the Play Store app.
- Go to an app’s detail page. To review permissions before installing, scroll to Developer and tap Permission details.
- Tap Install. Some apps will install right away. When you use an app, you can allow or deny individual permission requests before the app uses that type of data. For other apps, Google Play shows you all of the permission groups an app will be able to access before you install. This information can help you decide whether you want to install the app.
Checking permissions of an installed app
- Open Settings app.
- Tap Apps.
- Select the app.
- Tap Permissions.
- Turn off the permission you don’t want to provide to the app.
Keep in mind that some apps may not work properly when a necessary permission is not granted. If that occurs, you can either choose to continue disallowing access, uninstall the app, or give permission it’s asking.
Screen discoloration when battery is low
In general, any screen discoloration is an indicator of a bad screen assembly, which means that you have a bad hardware. In your particular case, the problem may be battery-related so you’ll most likely end up with repair (for battery replacement). Contact Samsung and see if they can check the phone for you. If your device is no longer in warranty, repair will not be free.
