Problem #1: Galaxy S6 won’t boot normally
Hello. I am hoping you can help me. I have been looking online on what to do as my Samsung S6 Edge decided it no longer wants to boot. It happened over the weekend and a few times I was able to get to the keypad screen to insert my password to open the phone however, now the furthest it will go is to the Samsung logo and then turns off. More often than not when I try to turn it on it only shows the make/model and then turns off. I have been trying to download the files from it on my computer although given it won’t turn on my computer does not recognize it.
Before it decided to no longer boot, I was having some issues with the storage. I received messages that the storage was very low and I would go then go to certain apps and remove the data. The most problemsome one was the keyboard storing data. I would clear the data and not too much later it would be at the same MB and saying the storage is low.
I did clear data on some apps/programs I probably should not have as a few weeks ago all my phone stock ringtones disappeared. But the phone was still working.
The last time it worked, I tried to stop the keyboard and then it started not booting. I am not sure if that is it as there is an option to stop the keyboard from storing data.
I have tried as you mention in one of your suggestions to hold the middle white button down and push start at the same time. The phone still will not boot. I can get as far as the Samsung logo and sound bite.
I would like to get files off my phone before trying to factory reset. I do have some things on the internal memory.
I greatly appreciate any advice you can offer.
Thanks! — Amy
Solution: Hi Amy. If your phone has reached this point, something is clearly preventing boot sequence to be completed. That means your phone will not be detected by another computer like when it boos normally. There’s nothing that you can do to change that. You either have to try to factory reset the phone, or boot it in download mode to attempt ROM re-install. Either of these two means losing your personal data.
Problem #2: Galaxy S6 overheating and fast battery drain issues
Phone is not charging as before. The battery icon shows that the charging is on. But the phone does not charge. This does not happen every time. The fast charger connected notification too does not come on everytime.
When the USB cable was connected to the Apple Mac pro it does not detect the Android device .
The phone has been heating too much while charging , right from April2015 . However this too does not happen each time. Happens about 40% of the times. Use to happen very often earlier. Not so much now.
There are times when the phone is not being charged yet heats up a bit while using it.
The phone not charging and fast charger not connecting is happening since about 15 days.
Once in a while it does charge but slower compared to earlier.
I have never taken the phone to the shop in the last 7 months to address the heating issue as over a period of time that has become less. — Madhurani
Solution: Hi Madhurani. All these symptoms can be caused by both software and hardware problems so your first task is to identify which of them is the real reason. Hardware problems can only be resolved by either having the phone replaced or repaired. Fast battery drain and overheating usually go hand in hand and suggest there’s only one cause. Sometimes, a bad battery is to blame while in some cases, an operating system or app glitch can cause them. In order for you to know which is which, you must do the basic software troubleshooting that we usually recommend in our previous posts.
These potential solutions include booting the phone in safe mode, wiping the cache partition, and doing a factory reset. If you haven’t done them yet, kindly refer to the steps below.
How to boot an S5 in Safe Mode
Third party apps, especially those that are poorly built, are often the reason for majority of smartphone problems. To verify if one of your installed apps is draining the battery power fast, or causing the system to constantly run tasks in the background, restart your S6 in safe mode and observe it for a full day. If battery consumption appears normal and the phone does not overheat, there’s a big chance that one of the apps is the culprit. To boot in safe mode, just follow these steps:
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.
How to wipe the cache partition on a Galaxy S6
The cache partition, also known as the system cache, often gets corrupted, especially during and after an update. Corrupted cache in turn can affect how apps behave so it’s best to ensure that the system cache is regularly maintained. To do that, just follow these steps:
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.
How to do a factory reset on a Galaxy S6
Often done as a last resort, a factory reset appears to be a necessary solution in your situation. Before you proceed with it, make sure that you have created a backup copy of your personal data (photos, videos, contacts, etc.).
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.
Do not install unreliable or unused apps
If you have lots of unused apps, don’t re-install them after doing a factory reset. They not only use memory space but they may also collectively help drain battery power faster. Keep in mind that some apps may require frequent communication with remote servers. Such task is taxing for the battery. Everytime there’s a demand to sync for an update like what social networking, shopping and some gaming apps do, your phone fires up the processor, triggering a series of tasks for other components. If this happens a lot, you can expect the power source to lose significant power even if the phone is on standby. Sometimes, power drain from such situation is so severe that the phone will appear to not charge at all even if it’s connected to a charger.
Keep your phone tidy and free of bloatware. If you can’t uninstall them, try to see if there’s an option to disable them instead.
Problem #3: Galaxy S6 loses battery power fast
I have a Galaxy S6. It was running perfectly and i didn’t do any updates to the main frame till may 2015. It continued to work fine till last August (2015) when suddenly it started to show major drop in battery life. Really from 100% to 1% in less than two hours and shutting down even at 50% without any solution.
i tried all possible beginners solutions as installing, calibrating software from Google Store and Battery doctor. None worked.
then i decided to lose the root and upgrade. i did upgrade to lollipop 5.1. It improved by 20 % only…now it would shut down at 35 or 25%. That was acceptable for couple of weeks now. Then again since yesterday, it became even more deteriorating, with power off at 80% or 75%. And when connecting to a charger it will start with 1% ..then if i open it it will show charging level 50%.
That does make sense? Do i need to change the battery though it’s costly for me?
is there anything i can do by myself? Thank you for help in advance. — Amr
Solution: Hi Amr. Please refer to our suggestion for Madhurani above. If nothing changes after doing all of them, have the phone checked for any hardware malfunction. Make sure to have the battery checked or replaced too.
Problem #4: Galaxy S6 no longer powers on
My phone has had problems charging. For the past several weeks while on the charger it would stop charging then charge and then stop, this occurs numerous times. It would say “use charger that came with device”. This is all I use.
Now my phone won’t charge at all and when I plugged the charger in it seemed to drain the battery. My phone is now completely dead. — Robert
Solution: Hi Robert. Have you tried using another charger to see if it’s a charger issue? If that won’t work, try have the phone replaced for a possible hardware failure.
Problem #5: Galaxy S6 Knox security tripped and won’t boot normally
I was using Chrome browser one day and the device restarted and the boot up the screen showed some fuzzy (matrixy) lines and now cannot pass the logo screen. I cannot enter recovery mode (volume up) to wipe/restore anything but can get it to go into download (volume down) mode.
I sent it to Samsung to get repaired but they say the Knox counter has been triggered and as such unauthorized usage and it’s not covered by my warranty. I haven’t rooted my phone (not this one anyway) so I don’t know what to do.
Any help would be great. — Simon
Solution: HI Simon. If recovery and normal modes are no longer accessible at this time, consider rooting the phone so you can then install stock or custom ROM. This is the only way to boot to normal mode again.
Try to use Google to look for sources on how to root and install ROM to your phone.
