Many have been complaining about their Samsung Galaxy S6 that reportedly won’t connect to the car Bluetooth after the Marshmallow update. The most frustrating part is that no one would like to take the blame. Owners call Samsung to seek help only to be referred to the car manufacturer, which will also blame the device or the company that built it for the problem.

So, whose fault is it, anyway?

Well, if the phone was able to connect to the car Bluetooth prior to the update, isn’t it obvious that the latest firmware messed it up? Samsung doesn’t want to acknowledge it and that’s the problem. In this post, however, I cited one problem sent by our readers. According to him, since the Marshmallow update, his Galaxy S6 can no longer connect to his car’s stereo–Pioneer AHX 4100NEX.

Read on to learn more about the problem as well as other app issues I included here.

Q: “Since the Marshmallow the upgrade I have been unable to connect my phone to android auto. I’ve tried several things to fix the issue that I’ve read on the blogs, but nothing works. Please help! Thanks! My stereo unit is the Pioneer AHX 4100NEX.

A: I think the new update already patched this problem. Actually, it’s not an issue with your car’s stereo, it’s all the firmware but Samsung already rolled out an update for this. Phil Nickinson of AndroidCentral.com confirmed his Galaxy S6 now works fine with Android Auto.

Q: “Hello. I have problem with Gmail. I do not get new mail although synchronization is on. I also think my battery is shorter with android 6.1. Did you now when will come out update for android 6.1?

A: If you’re using the official Gmail app, then try to clear its cache and data to reset it default settings. A problem like can easily be fixed by that. However, if you’re using the native Email app, try to remove your Google account from it and set it up again. That usually works.

  1. From any Home screen, tap Apps.
  2. Tap Settings.
  3. Scroll to ‘APPLICATIONS,’ then tap Application manager.
  4. Swipe right to the ALL screen.
  5. Scroll to and tap Gmail.
  6. Tap Clear cache.
  7. Tap Clear data, then OK.

About your battery, you need to further observe your phone to know for sure if the battery life was reduced. It could be that there are a lot of apps running in the background. You should compare how fast it drains its battery when it’s in normal mode and safe mode. Here’s how you boot your device in safe mode and I suggest you try using it for a day or two in this mode so you’ll know the difference:

  1. Turn off your Galaxy S6.
  2. Press and hold the Power key.
  3. When ‘Samsung Galaxy S6’ 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.

As to the next update (Android 6.1), we really don’t have a clue when Samsung and carriers would roll it out but I’m sure they’re already working on it now considering the many problems owners have been experiencing.

Q: “Music apps do not stream continuously. Apps like mixlr which always played in the background now buffer indefinitely when in the background. Amazon music almost always buffers.  Spotify is not as bad but still will stop streaming and buffer randomly. Has only happened since marshmallow update. Tried a factory reset with no luck.

A: It seems to me like the problem isn’t with the phone but with your internet connection. At least, that’s the most common cause when multimedia streaming buffers. I’m not sure if you’re connected to a Wi-Fi network or mobile data network but you should verify that your connection is good and fast. I understand you already did the factory reset to no avail but try doing the master reset this time. It’s basically just like the factory reset only that it reformats both the cache and data partitions to get rid of possible corrupt caches and data that might be causing the problem. Here’s how…

  1. Turn off your Samsung Galaxy S6.
  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: Calendar. yesterday all the future events disappeared from my calendar.  Past events remain. Past events with the repeat event option selected remain selected, but no repeat occurs for future events.  I cannot enter additional future events–I can however add past events.  When I check on my computer all the information remains intact on my google.  I have tried powering on and off.  I have followed your directions for repartioning the cache.  I looked at the directions for uninstalling and reinstalling the computer, but found that my application manager list includes 2 calendar apps, one with 0.00B the other with 216KB. Neither include an uninstall option.  There is an additional Calendar storage with 468 KB.

A: We actually received a lot of calendar-related issues in the past. Yours, however, seems like a syncing issue more than anything else. As you said, all events remain intact in your Google account, however, the Calendar app in your phone only display some of events and you can’t add new events either. So, the firs thing you should do is try to make sure Calendar is synced. If the sync is on and no events were synced, then it’s time you cleared the cache and the data of the Calendar app and you need to do for both of the apps that you see in the Application Manager.

  1. From any Home screen, tap Apps.
  2. Tap Settings.
  3. Scroll to ‘APPLICATIONS,’ then tap Application manager.
  4. Swipe right to the ALL screen.
  5. Scroll to and tap Calendar (do this to other Calendar app as well).
  6. Tap Clear cache.
  7. Tap Clear data, then OK.

Based on your description, I think this is the only thing you should do to make your Calendar work again.

Q: “I’m using the music app that came with my Samsung S6 called “Music.” I like the app and would like to use it even though I’ve read that it has problems. It works fine for me except… I cannot select and play a Playlist. The tutorials are worthless. They tell me how to create a Playlist, Add-to a Playlist, Edit a Playlist, Delete a Playlist but none of them says how to USE a playlist. I can select from multiple Playlists but I can’t get them into the player. However, if I create a single playlist, I can play it. But I have to delete it and create another in order to play the new one. Google wants me to use their player but the interface is ugly and the controls crude. BUT, it does work. Mahalo nui and Thanks for your help, Norm Pu’ukani Penick.

A: Ok, so you know how to create playlist and I assume you also know how to add songs to a playlist. If you have everything setup, just tap and hold the playlist and you can find options on what to do about it. Of course, you would have to do this in the Music app. I’m not really sure what the problem here is but if you were only wondering how to use a playlist, then that’s what you need to do. I have heard any problem with the Music app on the Galaxy S6. I hope this helps.

Q: “Hi, I had trouble with emails not syncing took your advise and I have identified it is the Google Calendar app that is causing the email to not sync etc., the trouble is I need to use both, is it a case of going to a Samsung store and getting a new phone?

A: I hope you already backed up your events with Google Calendar and that you still have copies of Email messages on the server. There’s one thing I want you to do for both apps to make them work again and that’s to clear their caches and data or to reset them.

  1. From any Home screen, tap Apps.
  2. Tap Settings.
  3. Scroll to ‘APPLICATIONS,’ then tap Application manager.
  4. Swipe right to the ALL screen.
  5. Scroll to and tap Calendar (do this to Email app as well).
  6. Tap Clear cache.
  7. Tap Clear data, then OK.

Now, setup your email first and make sure you sync everything including the calendar. That should do it.

Q: “I am one of many Galaxy S6 users experiencing a Snapchat record button lag. I have found (and attempted) prior solves for similar issues with no luck. (One suggested shifting phone to Developer Mode and unchecking NuPlayer – no such option exists and others have reported this).

Is this something you have heard of? Any suggestions on how to fix it? I work in social media and the lag is an issue for my job! Thank you!

A: Many have actually reported this problem and SnapChat actually rolled out a few updates about it already yet the problem remained. This must be an issue with the firmware and there’s nothing we can do about it unless Samsung rolls out an update that will also address this problem.

Q: “Some apps I downloaded from the Google Play Store are not working with mobile data. these apps are like whatsapp, waze, clash royal, full house casino, 8 ball pool. Other apps are working like google earth, internet, e mails, facebook, xtrade. I can’t figure out why, there are no data restrictions for these apps.

A: You should have specified what “not working” means to you. Do they open but crash? There are different kinds of “not working” problems when it comes to apps and without enough information, we can’t troubleshoot the problem. But try to uninstall those apps and install them again, that often works for apps that don’t work. Or, you may try doing the master reset:

  1. Turn off your Samsung Galaxy S6.
  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.

I hope this works for you.

Q: “Storage Space Running Out message. My Storage is critically low. Music files, 8.6GB. Contacts Storage App, 13.08GB. This seems to be the cause. Contacts is only 40KB. Need help to understand why the Contacts Storage is so large and how to reduce this. Thank you!

A: The Contacts Storage service is the one responsible in managing your contacts that are saved in the phone’s internal storage. Needless to say, the amount of storage it uses depends on the number of contacts that are stored in the phone. Yours, however, is unusually high so here’s what you need to do:

  • Backup all your data first. You may sync them with your Google or Samsung account.
  • Clear the cache and data of the Contacts Storage app.

Clear Cache and Data of Contacts Storage

  1. From any Home screen, tap Apps.
  2. Tap Settings.
  3. Scroll to ‘APPLICATIONS,’ then tap Application manager.
  4. Swipe right to the ALL screen.
  5. Scroll to and tap Calendar (do this to Email app as well).
  6. Tap Clear cache.
  7. Tap Clear data, then OK.

I hope this helps.
