Q: “After updating PASSWORD for my Comcast email account the stock Note 5 email program fails to send Outgoing email failing because of PASSWORD.

Change/update PASSWORD in the SETTINGS section of the email app, click DONE, app appears to then check both incoming and outgoing server successfully.

Review WITHOUT CHANGING the SETTINGS section, click DONE and incoming server passes but outgoing FAILS.  Reenter password in two locations and, again, incoming and outgoing pass. Review and again click DONE and, again, outgoing fails.

Obvious the changed/new password isn’t getting stored/retrieved correctly.

Samsung says reset/reload app OR install Comcast app. WHAT**?

A: The outgoing server failed to authenticate your account and your email client a few times already. Did it ever occur to you that may the outgoing server settings are incorrect? Whatever Samsung rep told you, I’m with it but it seems you didn’t understand it quite well. So, here goes…

#1: The reset means you have to clear the cache and the data of the Email app. This will remove your Comcast account forcing you to setup your email again. However, you will lose all your email messages especially when you’ve setup your account using POP3 server type. Here’s how you clear the cache and data…

  1. From the Home screen, tap the Apps icon.
  2. Find and tap Settings.
  3. Under the ‘APPLICATIONS’ section, find and touch Application manager.
  4. Swipe to the left or to the right to display the appropriate screen but to display all apps, choose the ‘ALL’ screen.
  5. Find and tap Email.
  6. Tap Clear Cache.
  7. Tap Clear Data, then OK.

#2: That’s right, Comcast also has its own email client and you can download it from the Play Store. It’s name is XFINITY Connect. Go search for that app and download. But if you may ask why you have to download it, well, it’s from Comcast and it bears the correct server settings already. All you need to do is enter your username and password and you should be ok.

Q: “Today around 1:30 EDT both of my gmail accounts popped up and said failed to sign in. when I click the message I receive:


  1. That’s an error

Error: disabled_client

The OAuth client was disabled

There’s also data under the request details pointing back to Google sites. Thinking I could fix this I deleted one of the gmail accounts, but when I try to add it back I get the same message when i tap the password field. Now I can’t add a gmail account and the gmail account won’t sync that I have on there. I’ve tried on and off WiFi and I’ve rebooted many times. Oh and I’m using the default mail app. Thanks, David.

A: It’s an issue with Google’s servers and it’s been happening for a few days already. Some owners that encountered it said theirs was fixed on its own confirming that it’s a server issue. There were, however, some who said that turning off sync for a few minutes and turning it back on would trigger servers to authenticate your account. Once you enter your password, everything will be back to normal again. Try that or wait it out. I understand you may be waiting for some important messages but there’s nothing we can do about it really.

Q: “I recently had the new Marshmallow update on my Note 5 and since the update my FB app will not show current posts.  Anything that is posted today will not show until tomorrow.  I’ve Cleared the Cache, Uninstalled/re-installed the app, and turned on/off my phone and it still will not work, it does however work on my tablet.  Will I need to take it in to T-mobile for support, or is there a fix that I can do myself?  Have others had this issue?

A: I don’t know if you’re referring to your own Facebook account’s wall or a page’s timeline but either way, try to check your settings to see if posts are scheduled to be posted in the future. Also, T-Mobile will just refer you to Facebook so better contact FB regarding this matter. However, before you do that, I suggest you backup your data and do the master reset as the rep would definitely ask you to reset your phone.

How to Master Reset Galaxy Note 5

  1. Remove your Google account and disengage the screen locks to make sure you won’t trip the Factory Reset Protection (FRP).
  2. Turn off your Samsung Galaxy Note 5.
  3. Press and hold the Volume Up, Home and Power keys together.
  4. When the device powers on and displays ‘Power on logo’, release all keys and the Android icon will appear on the screen.
  5. Wait until the Android Recovery Screen appears after about 30 seconds.
  6. Using the Volume Down key, highlight the option, ‘wipe data/factory reset’ and press the Power key to select it.
  7. 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.
  8. After the reset is complete, highlight ‘Reboot system now’ and hit the Power key to restart the phone.

Q: “OK Google come up and recognizes voice search 100% of the time.  It then displays ‘Offline Check your connection’ 100% of the time.  On wireless or not, this is consistent the FIRST time.  Clicking on ‘retry’ works about 75% of the time. Providing feedback has not make a difference, 100% of the time.

A: Well, most of time, it’s a connection issue. The first thing you should do if you’re connecting to a Wi-Fi network is to “Forget” that network from your phone and let it scan and reconnect to it. If this problem occurred just recently after an update, then wiping the cache partition may fix it:

  1. Turn off your Galaxy Note 5.
  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: “Since I got the phone update, I haven’t been able to update any apps from Google Play Store. I get that error code. I have plenty of phone space, and tried using wifi and my network, still get error code 495. I’ve restarted phone, tried download booster, cleared cache, stopped and started Google. still not updating apps in Google Play Store.

A: There are two thing you can do to try to fix Google Play Store error 495; first, clear the cache and data of the Google Play Store and Google Services Framework, or, second, remove your Google account from Play Store and add it again. I hope this helps.

  1. From the Home screen, tap the Apps icon.
  2. Find and tap Settings.
  3. Under the ‘APPLICATIONS’ section, find and touch Application manager.
  4. Swipe to the left or to the right to display the appropriate screen but to display all apps, choose the ‘ALL’ screen.
  5. Find and tap Play Store (Google Services Framework).
  6. Tap Clear Cache.
  7. Tap Clear Data, then OK.

Q: “Won’t let me post or comment on Facebook posts. My phone tells me that is can’t connect and to check my internet connection. Even though I’m connected to Wi-Fi.

A: It might be connected to a Wi-Fi network but it doesn’t guarantee it has an internet connectivity especially if you’re connecting to public hotspots. But assuming you’re trying to connect to your own network at home, try to “Forget” your network on your phone and let it scan, detect and reconnect to it. That way, you can be sure you’ve entered the correct credentials. If the problem persists, however, then it must be an issue with your network and immediate thing you can do to try to fix this problem is to reboot your network equipment such as your router or modem.

Q: “My exchange emails and calendar do not synch properly, in real time, often taking 3-8 or more hours to synch. Curiously, this does synch best when I’m on “do not disturb”, and it’s 4-6 am. I’ve tried all your prior suggestions, – they have failed.

A: What suggestions? It could have been more helpful for us to determine what the issue is if you included what “suggestions” you already tried.

Syncing problems occur due to various reasons and internet connectivity is one of them. Have you verified your connection is stable and fast? How about the syncing frequency? Have you checked if it was set to sync at a certain amount of time? Have you tried setting up your exchange account to make sure all settings are correct? If all these failed, have you tried doing the master reset?

Q: “Since downloading Marshmallow my phone doesn’t work with YouTube or the Google Play Store while connected to WiFi. It still works with 4G internet. I’ve tried a half dozen different WiFi connections (home, work, and places like Starbucks). My WiFi still works…just not for these. I can’t update apps because of this issue.

A: So your phone’s Wi-Fi was messed up and it’s because of that update. Try wiping the cache partition first, it that fails, do the master reset. If that fails as well, then you need to contact your provider to have the firmware reinstalled. There’s a chance the update was unsuccessful or it may have some corrupt files.

Q: “Three of the pre installed apps I like to use on the phone do not work correctly or at all. I have had to download a third party app in their place, but I prefer the pre installed apps.

1.Messages – does not allow me to attach anything (pix) to the text, I have to do it seperately.

2.Calendar – when I set up an appointment, it doesn’t allow me to set reminders.

3.Gallery – it doesn’t allow me to move pictures from one folder to another or at all.

A: When did these problems start? I’m certain they didn’t occur for no reason at all that’s why we’re always looking for possible causes. But since you haven’t included such information, let me answer your questions with ways I know would for these issues:

  1. For Messages that doesn’t allow you to attach pictures, turn off VoLTE. Open the Phone app, tap More, scroll down to Settings, tap VoLTE and choose Do not us VoLTE.
  2. As to the Calendar that doesn’t allow you to set reminders, back up all your appointments with Google Calendar and clear the cache and data of the Calendar app.
  3. About the Gallery that won’t allow you to move pictures, well, you can do so using My Files. Or, you may want to clear the cache and data of the Gallery app as well.

Q: “After updating to Marshmallow, my “Messages” does not work.  When opened it says “Refreshing …” but it never changes from that.  I tried following the instructions on this page for clearing the cache but that did not work.  Please help!  Thanks.

A: This seems to be a common issue with the app after the Marshmallow. Fortunately, it can easily be fixed and all you got to do is clear its cache and data. It should work after that.

Q: “The new Marshmallow update states that WhatsApp will not work with the new update is that true, I use whatsapp extensively, please advise before I commit to the update.

A: I don’t know where you’ve read that but WhatsApp is one of the most popular apps in the Play Store and behind it is a company and a group of developers that make sure it works the way it should. Now, tell me, if you’re the developer of a particularly popular app, would you release an update to make sure your app works perfectly with the new version of Android?

But assuming it’s true, it’s just a matter of time before the developer rolls out an update to patch the incompatibility issue.
