While Samsung rolled out the Marshmallow update to fix problems owners encountered, it seems that many have experience problems after updating their device. Among the most common problems we received from our readers is about their units that just froze for some reason and became unresponsive.

Others, however, said they can’t update their device to Marshmallow as it says it’s already up-to-date. Learn more about these problems and ways to fix them. I cited some problems that were sent by our readers below. Read them to know how to tackle each one in case they’ll occur to you in the future.

Q: “My phone just froze. I’ve installed no new apps, I know it had plenty of battery. Also, it keeps on display the time at which it decided to freeze, on the edge menu. The screen won’t turn on, the phone won’t restart when I press the power button. Pressing the home button won’t work either. I’m kinda freaking out right now… thanks for any help you can provide.

A: If this problem just occurred without any apparent reason, your phone may have just crashed. To deal with it, press and hold the Volume Down and Power keys (in that order) together for 10 to 15 seconds. The phone should reboot when you do that, although we can’t tell for sure if the problem returns or not. If it does, then you need to do the master reset after you’ve backed up your data.

How to Master Reset Galaxy S6 Edge

  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: “My phone will not update to Marshmallow.  It seems to be stuck on 5.1. The OTA says its up to date, Even downloading Smart Switch does not help and I’ve done the emergency repair and stripped it right back. A bloke at work, same phone, same provider got his fine. Help please. Cheers, Chris.

A: Firmware updates are often rolled out by region so it could be that you’re among the owners that may receive the update later than others. But I’m also wondering if your phone has been provided by the provider you’re currently connected with. There are variants that doesn’t get updated simply because the provider doesn’t support firmware upgrades. You should call your service provider about it, they can give you more answers than we do.

Q: “Hi, I did a root successfully, then I tried to flash it. I did a backup and then I started to install without wipe. The result was no booting and red text on the left corner “The kernel is not seandroid enforcing.” I can access to download mode. I tried with odin to do the original firmware again but without results.

A: Try flashing the stock firmware that has the same version as the custom one you installed. There are times when newer updates would prevent your from rolling back to the older version. Since you said you tried installing the original firmware, I assume you tried flashing the firmware that ran on your phone prior to rooting and the flashing of a new firmware.

Q: “Since update my data does not work unless I am in Wi-Fi spot. Have turned data on and off several times. Still doesn’t work. Even the phone loses connection with cell tower and takes forever to find signal again. Have done a hard reset back to factory settings. Same issues.

A: As to the data issue, it might have been just the APN settings that may have been reset or deleted during the process. However, when it comes to the cellular signal that keeps losing, either it’s a network issue or a problem with the firmware. Either way, you need to contact your service provider for that.

Q: “Hi. I am having a update problem ! It has since I have my phone almost a year never been able to update it! When I go through the process over settings it tells me that my phone is up to date! Though I know the system isn’t. I’d like to know how to update my phone (without computer) knowing it doesn’t work then simple way. Do you have any good tips?

A: Since already limited us to just working with the phone alone, well, there isn’t no other way. I have a feeling you have a variant of the S6 Edge that’s carried by a provider that doesn’t support software upgrades. And since you asked for tips that doesn’t require a computer, well, that’s that. No computers.

Q: “Hi, I was having a successful update of 6.0.1 Marshmallow on my device and was using it with a charm but one day suddenly when it was plugged in on charger, the phone restarted and was in boot loop of Samsung screen, it goes in download mode and firmware downloads are normal but never goes in safe mode or recovery mode or further then boot loop. The phone is barely 4 5 months use with no damage at all. The model is G925F. I had Updated The United Kingdom firmware earlier on it.

A: The firmware needs to be re-flashed but since you said you can’t boot it in recovery mode, I assume you can’t also boot it in download mode. So, basically, there’s nothing we can do about it, you need Samsung’s help for this.

Q: “I have Galaxy S6 Edge and I upgraded to Android 6 by OTA. After that, I have two problems; first, there is no app shortcut on lock screen although i can change settings of that but they are not on lock screen; second one is that text to speech service crashes and I can’t use it on any app (dictionary, Google Voice, etc). Thank you.

A: You said you have no Apps icon on the lock screen but even if you have, tapping it won’t bring you to the app drawer without unlocking your phone, right? When you unlock your phone, however, you are no longer on the lock screen but the Home screen and I’m sure there’s the Apps icon there. So, what’s the point in putting the Apps icon on the lock screen when you can’t even use it?

As to the text-to-speech issue, try wiping the cache partition first to see if that makes a difference. Follow these steps:

  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.

If it doesn’t fix the problem, then do the master reset.
