Problem #1: POP3 email account on Galaxy S6 not syncing properly after Marshmallow update

Since upgrading to Marshmallow, one of my three POP3 accounts on my phone isn’t syncing properly. On this particular POP3 account, I have it checked on my phone to never delete the email from the server when downloading to my phone. On my computer, in Outlook, I have it checked to not keep messages on the server. What I want is for emails to primarily go to my computer, and if Outlook is closed, then they will go to my phone. I do not want emails on my phone unless Outlook is closed.

Before the update, if an email did download to my phone, then it would disappear as soon as I opened Outlook and downloaded it to Outlook, which is exactly what I wanted to have happen.

Now, even after I download the email into Outlook, it also shows up on my phone, and it won’t disappear even though I’ve downloaded it into Outlook. The problem with this is I end up with a huge number of emails in my deleted box on my phone or I have to go in there 10 times a day and delete them out of my deleted box. Why won’t my messages disappear after I’ve downloaded them to Outlook? This seems to be an issue with the upgrade to Marshmallow because nothing else has changed, and it was working correctly prior to the upgrade to Marshmallow. Help! — Amy

Solution: Hi Amy. Email syncing process in your case involves at least three devices — your S6, your computer, and the server. Usually, a user must identify which of these devices is causing the problem but if the only change you’ve done is to update your S6 to Marshmallow, then troubleshooting must be focused on this device only. The first thing that you can try is to delete the cache and data of the email app on your phone. If the glitch is being caused by outdated or corrupt local app cache, then this procedure should fix the problem right away. Keep in mind that clearing an app’s data is the virtual equivalent of uninstalling an app so be sure that you have all the information you need to reconfigure your email account afterwards. Here are the steps on how to delete an app’s cache and data:

  • Open the Settings menu.
  • Tap Apps (some versions may show Applications or Application Manager).
  • Tap the email app.
  • Tap Storage.
  • Tap Clear Cache, then Clear Data (in this order).

After tapping the Clear Data button, go back to the home screen, tap the email app again, then setup the email account again.

If reconfiguring the email app won’t help, you can then wipe the system cache. Wiping the cache partition has proven effective in fixing minor app-specific issues as well as freezing and random reboot issues. If you haven’t done this step yet, simply 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.

Problem #2: Verizon Voice Mail app not working after updating Galaxy S6 to Marshmallow

Since updating to Marshmallow 2 days ago, visual voicemail just gives me an error on the drop down screen. Spent an hour with Verizon this morning trying a bunch of things to fix it, however she finally checked their ticket logs and found that a number of people are having this issue since updating.

I took out the SIM card, disabled and re-enabled visual voicemail on my end and then manually on her (Verizon person’s) end.

Guessing you guys can’t fix (which is surprising because I feel like you fix everything…except stupid Lollipop battery issues, but that is another story 😉 )

Please let me know if you have a solution(s) or at least let other people know that they are not the only ones dealing with this. They must beta test the heck out of these, but sometimes it just doesn’t seem like it.

Thanks!  — Jenn

Solution: Hi Jenn. Any app-specific problems are beyond our expertise. Verizon’s Voice Mail app has always been problematic even with older Android versions and only their developer team can fix whatever problem you may have right now on your device. The most that you can do is to perform a factory reset. If that won’t help, that’s an indication that the app is poorly coded, or not yet fully compatible with Android Marshmallow. Fixing the problem requires tweaking some codes of the app which we can’t do.

Problem #3: Some Galaxy S6 apps disconnects from Wi-Fi after Marshmallow was installed

After “upgrading” to Marshmallow 6.0.1, I am experiencing issues with apps staying engaged to either Wi-Fi or 4G signals.

For example, I have a Sonos system that relies upon a Wi-Fi signal. As long as the app is up and running and is on the screen, there is no problem.  However, when I, for example, check an email on my phone, the app disconnects from all signals.

This happens with all apps including Kik messenger. If I have Kik open and am messaging, everything is fine and normal.  However, if I am not active on kik and in another app, kik acts like my phone is completely off and no messages that are sent to me appear in my feed when i open the app again.  It takes like 30 seconds for them to flood in and the person who sent them however long ago they sent them does not get the notification that they have been delivered until i open the app, where previously, as long as the phone was on, they would show as being delivered,  Finally, if I send a video message in kik, I have to wait for it to completely upload and be delivered before moving into another app. If I send a video message and then check an email before it is completely sent, when I come back, the video has not been sent.

It is like if I am not completely engaged and active on an app, the app acts like the phone is completely off.

Before the update, even if the app was just running in the background (Sonos) or the app had not even been opened, it would still receive messages without being open or running in the background (Kik).

Your help is sincerely appreciated. — Christopher

Solution: Hi Christopher. Android Marshmallow is a developing system at this time and some apps may not yet be properly coded or tested for their full functionality with this OS. The developers may still be working with their products at this time to make them compatible with Marshmallow so your course of action includes doing the basic software troubleshooting, or uninstalling the problematic app.

Try to wipe the cache partition  (steps provided above) first. If nothing changes, consider performing a factory reset by following the steps below:

  • 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 Volume 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.

No one wants to do a factory reset, especially after a major update but it may be your only choice for resolution.

If wiping the cache or factory reset won’t fix the problems, try to contact the developer of the apps involved to see if they can provide direct assistance.

Problem #4: Galaxy S6 screen has dark blue color

I’ve had the phone for a few months already and had no problems until now. I had a baseball game and was on the bus and using it with no problems at all. but when we got to the field I put my phone away in my bag and from there I don’t know what happened to it (because I was on the field).

when we got back on the bus and I turned on my phone there was blue splatter behind the screen (almost like someone flicked a paint brush on it) but it started off minor and ten minutes later started shutting off and resetting itself. every time it happened the blue splatter got bigger and bigger. when I got home I just plugged it for the night and hoped it would fix its self but instead now it’s entirely covered with a dark blue/black color except for the edge of the screen.

What happened to it? Can I fix it myself? Do if have to bring it in somewhere to get it checked out? If so about how much will it be for the dysfunctional part? Thank you. — Eric

Solution: Hi Eric. Your phone’s screen may have been physically damaged while you were playing. The screen assembly is composed of three major components — LCD, digitizer, and flex cable. Damaging any of these components can result to the problem you describe here and the only way to fix it is to have the phone repaired. There’s no software fix that you can do on your end to resolve a screen assembly issue. If the phone is still covered by a  warranty, make sure that you contact Samsung for screen replacement.

Keep in mind that you may have to invest in the repair process as any physical damage automatically voids the warranty. The only reason why you want Samsung to fix the screen is to ensure that it’s done properly. Screen replacement procedure can be tricky and may result to more issues if not done correctly. We don’t recommend that you do it yourself for this reason.

If you want to do it yourself though, try searching for online resources via Google for instructions.

Problem #5: Galaxy S6 won’t connect to home Wi-Fi after a trip

I am currently living on the East Coast. I recently traveled to the West Coast for a conference and before leaving I was connected to my Wi-Fi network (aka JS_HOME_16). On my return, I am unable to connect to the previous network and even worse, it does not appear on my Wi-Fi list of possible connections. In turn, the Samsung Galaxy S6 automatically connect to a router that I am currently using as a Wi-Fi extender in the house. The previous Wi-Fi connection (JS_HOME_16) was coming from an all-in-one box (Comcast router and modem device). I thought it may be a connection issue, but my laptop and tablet are connected to JS_HOME_16 without any problem. And, for some reason it does not even appear on the list of Wi-Fi connections on the phone, as mentioned before. I died a restart on the phone and follow simple steps to solve the problem, but I have not been able to resolve the issue yet. I recently updated into Android 6.1 on my phone. Do you guys have any recommendations or advice? Thanks in advance! — Josue

Solution: Hi Josue. An issue like this usually happens due to a caching glitch of some Android device. Make sure that you wipe the cache partition first before attempting another connection to your home Wi-Fi.

After you refresh the system cache on your S6, restart all networking devices (modem, router, Wi-Fi extender, etc) and your phone. Try another connection.

If the issue persists, boot your S6 to safe mode before connecting to your Wi-Fi. Sometimes, third party apps can create conflicts related to mobile data and Wi-Fi connections so preventing them from running before a connection is good. Here’s how it’s done:

  • Turn the phone off.
  • Press and hold Power button until the Galaxy S6 logo appears.
  • Once you see the S6 logo, press the Volume Down button while releasing the Power button.
  • Keep holding the Volume Down button until the phone is done rebooting.
  • After the reboot, “Safe Mode” should be shown at the bottom left corner of the screen.
  • Release the Volume Down button.
  • To exit safe mode, simply restart the phone.

  1. I will say I just tried it with powersave off and it seemed to work correctly. Hopefully that will fix the data issues as well. Seems Googles powersave functions and Samsungs don’t work well together.

  2. There is a problem with and S6 on Marshmallow. Most of the reported problems are problems. 1) the screen a noticeably darker on Marshmallow to the point that I’ve had to turn my brightness up from 1/4 to 1/2 to make it readable. 2) the voicemail app pops up with an error message all the time 3) gmail sync is broken beyond belief – gmail does not get push notification and does not sync for new mail until you open it, calendar sync has an error message on it. there were Marshmallow reports of sync issues with google and it was stated that an app update would fix this but does not appear to be the case on the S6 so far 4) wifi and mobile data randomly fail all the time and apps act like no internet can be found. turning off and on for wifi or mobile data brings it back but I have continually had to do this throughout the day since Marshmallow. I have cleared my cache and the problems persist. This article is helpful but is not addressing the very real problems of Marshmallow on the S6.
