Problem #1: Questions about Galaxy S6 My Knox

Good day, I have two questions. I currently have My Knox set up on the S6. When I set the VPN up in the settings of the device it connects properly and provides a connection to the device outside the container. The container connection itself is not protected when I check the internet apps in both environments. However I still have access to the network from both inside and outside the container. 1. When I use the Always-on VPN in settings, the connectivity inside the container stops completely. Is there a way to set Always-on VPN outside the container and also have network access to the Knox container? (I want to run a VPN in the container as well). 2. Since I want to run a VPN inside the container as well, is there a native VPN capability in My Knox or am I stuck with running a third-party app? (seems silly to flaunt the security capabilities of Knox and not provide secure data transmission from/to the container, but it seems that’s what I am finding…). Thanks! — Jason 

Solution: Hi Jason. There’s not much official documentation how Samsung’s My Knox offering works so we can’t provide a clear and direct answer to your queries. As far as we know, there’s no GUI (graphic user interface) for the current version of Knox VPN that users like you can use to change some settings. Whether this is by design or a limitation, only Samsung knows. We don’t have the complete picture of your phone setup, given the limited information you include in your problem description, but we think the following information taken from Samsung site on how to secure Knox Workspace app data will help:

About data security

Knox Workspace can secure data while in:

  • Storage – When an app in the Knox container saves data on the device, the data can be encrypted for storage, using On-Device Encryption (ODE). Use the new Chamber to keep your files even more secure. The Chamber is a folder inside the Knox container that is secured with defense-grade Sensitive Data Protection (SDP) technology. Data remains encrypted even after the user has exited the Knox container or has turned off the device.
  • Transit – When an app in the Knox container sends data to or receives data from the Internet, the data can be encrypted through a Virtual Private Network (VPN) connection.
  • Real time – Use Knox Active Protection to monitor your device status. Knox Active Protection provides an overview of device information including battery level, storage, RAM, and system security. If you have Knox installed on your device, Knox Active Protection (KAP) will be automatically enabled.

Knox Workspace supports these types of VPN models:

  • Device-wide VPN* – All outgoing traffic from the device goes through the same VPN connection. In this case, you use the Android VPN client that is preloaded with the device. This method is not recommended as it is not as secure as the next two methods. If you are using personal Knox this is the only VPN method available.
  • Container-wide VPN – All data sent to and from the Knox container goes through the same VPN connection. With this model, you use a more powerful Knox VPN client, which supports a wider range of more secure VPN protocols.
  • Per-app VPN – You can configure up to 5 separate VPN connections and assign container apps to VPN connections. With this model, a container app can have its own dedicated VPN connection. You need the Knox VPN client for this model too.

As with other Knox policies, IT Admins have the option to enable and set up these features to meet enterprise policies.

*You can use Knox to manage VPN connections, but only for user accounts you control. This typically includes the default user and any Knox Workspaces you activate.  VPN connections for apps installed in user accounts you don’t control, such as those created for Android for Work managed profiles, must be managed separately.

Should you find the above information not applicable or not relevant in your case, we strongly recommend that you contact Samsung itself.

Problem #2: Galaxy S6 won’t charge properly

Series of events:

-Picked up phone from counter to find that it had shut itself down to protect from overheating (it had also curiously shut itself down the day before, but there was no message why).

-Didn’t think too much about it, but found that it wouldn’t charge using the same cables and chargers I have been using all along.

-Turned the phone off, plugged it in, and it seemed like it was going to charge so I left it overnight.

-The next morning, the charge had stalled at 70%.

-Spent the day trying to figure out the problem, but could never get the phone to charge while it was turned on (seems to charge okay when It’s turned off).

Steps taken in order:

  • soft reset
  • wiped cache partition
  • factory reset
  • drained battery to zero, plugged it in, booted it up, and this time it charged to 100% while on.

Figured I had the problem solved, but after draining it to 85%, I plugged it back in to see if it would charge (a strange thing happened – more on that below), and it would not charge again (no lightning bolt symbol on the battery symbol).

Okay, so here are the oddities:

-Phone will charge it if is turned off

-If after restarting my phone with less than a full charge, I plug in the charger, I get the brief charging sound, the screen quickly rotates from vertical to horizontal, then goes dark (this happens in less than a second), and then I get two tiny X symbols in each corner of the lower part of the screen (next to the home button.

-The charging red light does not come on.

-My phone neither charges nor drains while plugged in

– stays on 85%

Of course, no one wants to have to turn off a phone just to get a full charge. There has to be something in these details that would explain what is going on. Right? — Michael

Solution: Hi Michael. Try booting the phone in safe mode before attempting to charge the phone again. This will help you check if the glitch is being caused by a  third party app/service or not. To boot in safe mode, here are the 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.

If the problem stays while safe mode is enabled, do another round of factory reset and observe the phone for 24-48 hours. Make sure that you don’t install anything during the observation period. If the same charging behavior happens, find a way to have the phone replaced.

Problem #3: Marshmallow on Galaxy S6 causing Bluetooth pairing issue with Panasonic car radio

After Marshmallow 6.0 update, my S6 Verizon phone will no longer pair to my 2014 Toyota Highlander which has a Panasonic radio system. Toyota replace the radio…didn’t fix problem. Toyota radio has all latest factory updates. At the Toyota dealership my S6 paired successfully in another Toyota with a different brand radio other than Panasonic. Verizon gave me a new S6 which already had Marshmallow installed but didn’t fix problem. My wife has a S7 and it pairs OK in the Highlander. My S6 pairs OK in my 2009 Mazda.

The Samsung rep at Best Buy Store checked my S6 settings and that I didn’t have any APPs that could explain or fix the problem and even went to my Highlander in the parking lot and try pairing. The Samsung rep also started my S6 in safe mode and it still wouldn’t pair. The rep also did a complete re-boot and re-load of Marshmallow 6.0, but my S6 still would not pair. A friend of mine has an AT&T S6 with 5.0 Lollipop which paired in my Highlander, and when he got the AT&T Marshmallow 6.0 update, it still pairs in my Highlander. I told Verizon Tech Support that it’s my opinion that the problem started when they added their tweaks to 6.0 and pushed out. Presently I have over a year remaining on my Verizon S6 contract, and it would cost me $360 to upgrade to a S7, which I’m not going to do, and Verizon said they won’t help with the upgrade cost. — Jack

Solution: Hi Jack. This type of problem involves multiple factors so you must ensure that you have all of them covered. These factors include:

  • Samsung hardware
  • Operating system of the phone
  • Phone Bluetooth version and compatibility with other devices
  • Car radio hardware
  • Operating system of the car radio
  • Car radio Bluetooth version and compatibility with other devices

Bluetooth communication between devices only works if both hardware and software of the two devices are compatible. Usually, Bluetooth problems only occur when one device uses a different protocol (like Bluetooth Smart) than the other (like “classic” Bluetooth). Most smartphones, including the Galaxy series phones, are using Bluetooth Smart. We can’t say for sure if there’s a hardware incompatibility between your phone and car radio but it’s worth checking.

You don’t need to focus solely on your Samsung device in this case. As far as bluetooth troubleshooting is concerned, you are limited to the things you already tried like booting in safe mode, wiping the cache partition, and factory reset. If those steps won’t help, you can assume that the issue must be on the other device.

You have to make sure that you troubleshoot your car’s radio system.  We are not familiar with all car radio systems out there so we can’t provide any specific step that you can do. In general though, you want to ensure first that you delete all existing profiles from the system before attempting another connection. If you don’t have any idea how to do it, make sure that you contact the manufacturer for support.

Problem #4: Galaxy S6 won’t turn on

Hello. So last night I was charging my phone at a friend’s house and everything was fine. Got home, passed out and when I woke up today my phone was dead. Put it on the charger and nothing happened. Tried 2 other chargers, and my car and still nothing. Took it to At&T and all they said was I had to file a claim for a replacement.

This really just happened out of nowhere. I didn’t drop it or anything. I always take care of my phones, and have had a case on it since I purchased it a little over a year ago. This just randomly happened. Is there any hope for this phone? If not, is there any possibility of getting anything off it? (Pictures, unsaved contacts, etc..) Also, I am not sure what android version I have, I just update it whenever one becomes available, and just did one about a month ago. Thank you for your time. — Ryan

Solution: Hi Ryan. There’s very little to nothing an end-user can do if his/her device won’t power back on. The best that you can do right now is to check if the phone will respond if you try to boot it in other boot modes like Recovery mode, Odin mode, or Safe mode. If you can turn it on to Recovery mode, you may be able to resolve the problem by wiping the cache partition. If that won’t work, a factory reset may. Here’s how:

  • 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’/‘Yes — delete all user data.’
  • 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.

If you can’t get the phone to boot to recovery, try Odin mode or Download mode. In this mode, your only option is to flash a stock or custom ROM. Doing this procedure will delete everything from the phone. To boot in download mode, follow these steps:

  • Press and hold the following three buttons at the same time: Volume Down key, Home key, and Power key.
  • When the phone vibrates, release the Power key but continue to press and hold the Volume Down key and the Home key.
  • When the Android System Recovery screen appears, release the Volume Down and Home keys.

If you’re lucky though, you may still be able to boot the phone up in safe mode. This will allow you to back up your files to another device. Refer to the steps above on how to boot in safe mode.

If all the three hardware button combinations won’t work, or if the phone remains unresponsive whenever you attempt to do them, you’re out of luck. Have the phone replaced.

Problem #5: Galaxy S6 becomes unresponsive after an update

Hi. Firstly good job on welcoming a challenge as I have one for you. A little bit on the problem. 1. Applied system update as requested. This ran as normal then after finishing the update the phone rebooted normally, SAMSUNG splash screen etc. All looked normal but then screen went blank and was left with the blue/green steady notification light and has been there ever since. 2.Ran through all the usual and then some, trying to get some sign of life. Ran through as suggested by your good selves but unfortunately no dice. “Samsung Galaxy S6 Edge won’t turn on or boot up.” I have contemplated removing the battery to give the board a chance to reset. What’s your take on this? I’d appreciate your thoughts on this problem. Thanks in advance. — Pete

Solution: Hi Pete. If the software troubleshooting you’ve tried didn’t work, then the phone might have been bricked. If your phone no longer has warranty with Samsung, your plan in opening it up and replacing the battery may not hurt. OTA updates seldom causes the phone to become totally unresponsive (unless you modified the official software by rooting/flashing before the update) so you also want to call the attention of your carrier for this one. Carrier-initiated updates may contain coding problems so it’s good if you report the issue to them.

Problem #6: Galaxy S6 Edge screen stops working while playing Pokemon Go

I have a Samsung S6 Edge. I was playing Pokemon Go when the screen froze. The phone was still responsive to button presses and the “back” and “apps” touch sections on the screen next to the center button. I performed a soft reset, started the phone in safe mode, cleared cache, rebooted phone. All still showed the Pokemon app running. The screen remained unresponsive to touch. I performed a factory restart. Screen still remained unresponsive to touch. I bought a new phone and left the S6 edge turned off for a month. I randomly turned it on and the screen was working again. Within a few hours it was unresponsive to touch. 90 minutes later it was working again. An hour after that, unresponsive to touch again. Any ideas? — Samirah

Solution: Hi Samirah. As mentioned in previous topic, if software troubleshooting won’t work, then you can assume that the phone is suffering from a hardware malfunction. Try having the screen assembly replaced. You can call Samsung to do that for you even if the warranty’s out already.
