Q: “I updated to marshmallow yesterday and I was trying to make a call this afternoon I tried this person a few times. I had a message on my screen saying ‘Unfortunately contacts has stopped working’ I pressed ok and the screen went black then the samsung logo came on the screen and its pulsing, the blue LED light is on at the top constantly and the green one next to it is pulsing. I cannot turn it off or on, button pressing does nothing.”

A: It appears like the system crashed in your phone though I’m not sure about the cause of the error message prior to the blacking out of the screen. Press and hold the Volume Down and Power keys together for 10 seconds to reboot the phone. After that, clear the cache and data of the Contacts app. If that won’t do it, then a reset may be necessary:

  1. Turn off your Samsung Galaxy S6 Edge.
  2. Press and hold the Volume Up, Home and Power keys together.
  3. When the device powers on and displays ‘Power on logo’, release all keys and the Android icon will appear on the screen.
  4. Wait until the Android Recovery Screen appears after about 30 seconds.
  5. Using the Volume Down key, highlight the option, ‘wipe data/factory reset’ and press the Power key to select it.
  6. 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.
  7. After the reset is complete, highlight ‘Reboot system now’ and hit the Power key to restart the phone.

Q: “I dropped my phone from a balcony and unsurprisingly the screen and back cover cracked.  I am currently in the process of replacing them myself but the problem is the phone will not power on and the charging light does not even turn on.  I am not sure if I need a new battery or maybe even the phone is scrapped hope you guys can help thanks.

A: Apparently, there’s no way for us to verify that and there’s also no guarantee that a new display panel is all that’s needed to be changed to make it work again. So, please, seek help from a technician in your area so he could do further tests and observe what really is the problem with your phone.

Q: “Used the lightening charger with the lead it came with for weeks until I downloaded marshmallow.  Now I can only charge on wireless pad.  Took it to phone provider and they plugged it in and worked. I have checked the port and all is clean and free of dirt. Any help would be appreciated.

A: At least, we know that the phone will charge if plugged in. So, the problem should either be in the charger or the cable. Try out a new charger and see if the works. If it has something to do with the firmware, then try wiping the cache partition first and then the master reset if that won’t 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.

Q: “I was using my phone and than suddenly it turned off, I plugged it in the charger and it wouldn’t turn on, it went on but only as far as the Samsung GALAXY S6 Edge logo than it completely turn off and repeats that over and over. When I clicked the up button, power button and main button it went to the load of settings I tried to backup and restore and reboot to bootloader (the last one was an accident) but none of them have worked so im hoping you can help me.

A: Try booting it in safe mode and see if it can successfully do that. If it can, a factory reset might just fix the problem for you, otherwise, try booting it in recovery mode, wipe the cache partition first if that won’t work, then do the master reset. Follow the steps in wiping the cache partition above and the master reset in the first problem.

Q: “I purchased my phone in August. I took really good care of it and then one day i woke up and went to school. I was in a lab and plugged it in and the red light went on for charging. I came back a few minutes later and the light was off and the back was hot. I unplugged it and it would not turn on. I brought it back to rogers and they diagnosed it as a water damaged item. But I am positive I never got it wet. The device does not boot or show that it will charge at all. Suggestions? Thanks in advance.

A: You can check if the Liquid Damage Indicator (LDI) is tripped by remove the SIM card tray and looking at the small sticker inside. If it’s white, then you can claim warranty but if it’s red, then the technician was right by diagnosing it as a water-damaged unit.

Q: “I have owned my phone for about 4 months now. Today I plugged in my S6 Edge for the first time ever to charge in my car. When I plugged it in it made a weird ticking noise and it signaled that it was charging but the percentage kept going down until it died. When I got home I plugged it in using the original charger and notice it was charging extremely slow. The phone has been charging for the past 2 hours now and it’s only on 15%. Before today my phone charged extremely fast thanks to fast charging. Anything I can do?

A: Try booting your phone in safe mode and charge it while in that state. The purpose of this procedure is to know whether it has something to do with your third-party apps or not. If the phone charges fine in safe mode, then it means some of your apps–the ones you downloaded–are draining the battery faster than it can take in. You need to find those apps and disable or make sure they’re closed when charging.

  1. Turn off your Galaxy S6 Edge.
  2. Press and hold the Power key.
  3. When ‘Samsung Galaxy S6 Edge’ appears, immediately release the Power key and then press and hold the Volume Down button.
  4. Continue holding the Volume Down button until the phone finishes the restart.
  5. When you see Safe Mode on the lower left corner of the screen, release the button.

If the phone is not charging normally in safe mode, then try turning it off and see if it charges fast when all components aren’t powered up. If so, then you need to reset your phone as the problem might have something to do with apps and the firmware.

Should the problem persist even if the device is turned off, then it’s time you visit a technician and have it checked.

Q: “Already had system reset for not charging. Now still not charging again. Shows power sharing cable connected when there isn’t one. Got it last December with same apps. Worked fine for 4 months.

A: Try downloading that Power sharing app and see if that remedies it, if not, then you really have to reset your phone to fix this problem.

Q: “Battery percentage drops like us no one’s business at some points… today it dropped from 6% – 3% in like 10 seconds when scrolled the notification bar down. Please help. That’s not the only instance. Please help.

A: If the phone is hot, then maybe there’s a ton of things running in the background. Try booting your phone in safe mode and see if the battery drain goes back to normal. If not, then try doing the reset. Lastly, have it checked, it might be a battery or hardware issue.
