Problem #1: Galaxy S6 can’t send SMS and MMS

Since the last software upgrade I have had issues with messaging. I can not send SMS or MMS to a contact that does not already have a thread going. I cannot download any MMS and randomly the messages I can send are getting attached to threads not associated with the original recipient. When that happens it is switching the name/number at the top of the screen to the number of the person associated with the thread it is being attached too. Once that happens, further messages are between me and that new individual AND the person I intended to message. PLEASE HELP. This is not very convenient! — Mike

Solution: Hi Mike. This may be caused by a corrupted Messaging app you’re using. Try to re-install the app or delete its cache and data (if it’s a pre-installed one). To do that, follow these steps:

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

      Once you’ve cleared the messaging app’s data, restart the phone and try to check if SMS  and MMS works normally. If the issue remains, try using another Messaging app. There a many free ones in Google Play Store.

      For a more drastic solution, you can try to do a factory reset to ensure that any firmware related glitch can be eliminated. It should also bring all settings of your messaging app to default. To factory reset your S6, follow these steps:

          • 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.

          Problem #2: Galaxy S6 stopped charging

          About 2 weeks ago, my phone started getting hot all the time and glitch a bit when scrolling thru the apps. “I didn’t do anything different or download any new apps”. It stopped being hot for a few days, a few days went by then I charged it right before I went to bed a few days ago to 100%. I unplugged it and went to bed, woke up the next day and my battery was almost drained, i thought it was kind of odd. So I plugged it back in to charge it again and took all day to reach 100%. I’ve never had issues with my S6 except for the last 3 weeks.

          I’ve cleaned my charging ports and my cables are good. I’ve also put all my apps to power saver all the time, deleted all the apps I don’t use. What could be the problem? I haven’t not done a soft reset or cleared caches, I don’t know how to do that. Any help would be appreciated, thank you in advance! — JD

          Solution: Hi JD. This problem can be caused by either software or hardware. The approach to determine where the problem lies is by doing basic software troubleshooting first. If all software troubleshooting have been exhausted, you can then assume that you have a hardware problem at hand.

          In your case, the first troubleshooting step you want to do is by observing how charging works when safe mode is enabled. Here are the steps on how to do that:

              • 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.

              Safe mode won’t allow third party apps or services to run. If one of the apps you installed is the root of the issue, the phone should charge normally in safe mode.

              On the other hand, if nothing will change even when safe mode is on, don’t hesitate to do a factory reset (steps provided above). And like what we mention above, you can assume that you have a hardware problem if nothing will change after a factory reset.

              Problem #3: Galaxy S6 calendar appointments not showing

              I have been using the default Calendar app preloaded on my Samsung Galaxy S6 (T-Mobile). I typically enter appointments as an EAS (Exchange ActiveSync) calendar appointment, so that my husband can have access to the appointments also as we share that msn account. About 5 days ago, when I clicked on the calendar, none of my appointments showed up, old or new. Nothing else odd had happened to my phone, and I can still access email and contacts. The appointments entered by my husband through his Google calendar do still appear. This is true whether the appointments are checked on MSN through our computer, through his phone, or through my phone. I have tried syncing through the calendar app and through the settings button to manage accounts. I don’t know if the phone had recently downloaded an update that might affect this function, as most updates happen automatically, and the phone is fully updated. I would appreciate any advice you can offer that might make my appointments reappear. Thank you. — Anne

              Solution: Hi Anne. In case you’ve installed an update prior to noticing the problem, the first thing that you want to do is to clear the phone’s system cache. Sometimes, updates can corrupt the system cache so it’s refreshing it may be helpful. This will force the phone to create a new one, which may help in fixing the problem. These are the steps on how to wipe the cache partition:

                  • 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.

                  Should wiping the cache partition won’t do anything, the next thing that you want to do is clear the email app’s cache and data (steps provided above). After that, make sure that re-configure your email accounts on the email app again. This should fix the issue.

                  Problem #4: Galaxy S6 Edge+ keeps showing Samsung Gear VR screen popup

                  I bought a new Samsung Galaxy S6 Edge+ which I’ve had for about 6 months. I haven’t had any issues with it up until a few days ago. First it started out with me not being able to charge it. My friend had the same issue and suggested I used the wireless charging, which works. We thought maybe the charging port was dirty. Then my phone started to glitch. The screen would turn black and had a small “x” in the corner. It would make a weird noise which I did not have set for a notifications sound or anything like that- I’ve not heard it before. Then the Gear VR screen would pop up. In between each glitch I can charge my phone through the port. However, sometimes that spazzes out too and I can’t charge it regardless. I put my phone on safe mode to see if that would isolate the problem. But, it still glitched. I have read about the hard reboot and I am thinking about doing so to see if the this problem will be resolved. Do you have any idea about what this problem could be and how to fix it? Thank you for your time. — Delaney

                  Solution: Hi Delaney. To address the Gear VR screen issue, you must disable the said app to prevent it from popping up again. Here’s how to do it:

                      • From any Home screen, tap Apps.
                      • Tap Settings.
                      • Scroll to ‘APPLICATIONS,’ then tap Application manager.
                      • Swipe right to the DOWNLOADED / ALL screen.
                      • Scroll to and tap the app that has Gear VR in its name.
                      • Tap Force Stop or Disable.

                      To address the charging issue, please refer to our suggestion for JD (second issue) above.

                      Problem #5: Galaxy S6 can’t open external links from Facebook and YouTube

                      I keep getting messages on my screen in grey oval boxes that state there are different types of I/O failure. It generally affects Facebook which I have uninstalled then reinstalled several times. My phone won’t allow me to open any external links from Facebook. It also affects Youtube and other clips I try and watch and my phone just tells me it can’t connect despite being connected to Wi-Fi or 4G. It now occurs far more frequently than before and it only happened a few times a day and I would turn my phone off and on again to temporarily solve the issue. The message now displays as soon as I turn the phone on. I have installed lots of different anti virus apps and malware apps but they picking up anything. I have Googled the issue and there aren’t any relevant results. Any help would be very much appreciated. Thanks in advance. — Gavin

                      Solution: Hi Gavin. If your issue only happened recently, then perhaps an Android update or app update may have changed some settings in your phone. Since we are yet to encounter the same case that’s being caused by a malware or virus, we don’t think using an antivirus will actually help. You want to do a factory reset instead to ensure that you restore the settings of the device back to their default, as well as eliminate potential bugs from previous Android update. Please refer to the steps above on how to do a factory reset.

                      Problem #6: Galaxy S6 can’t receive longer SMS

                      I have a texting issue on my phone. I got my phone a few months ago and when my wife text me one of two things would happen: if it was short no problem but if it is a mid size text I do not receive it. She has a iPhone.

                      I thought it was just an issue with her phone so she has just been sending only short texts to me. We have tried on occasion for her to send me a longer text but still the same. I seem to be getting text from all other contacts and of all lengths no problem. However if you don’t get a text you have no idea if you were ever supposed to have receive one.

                      Then the other day my manager at work was sending me mid size text and I never received them. I did receive the short few word texts from him no problem. I do not know what kind of phone he has (maybe an iPhone but cannot confirm). Why am I not receiving only some text?

                      This issue has been like this since I purchased the phone 4 months ago. Things I have already tried: had A&TT give me a new SIM card, Cleared cache, de-registered from iMessage (even though I have never owned an iphone I still tried, soft reset. What am I missing? Thank you for any help. — Billy

                      Solution: Hi Billy. We don’t understand what you mean by “mid-sized” text messages but if you’re referring to SMS that exceeds the standard 160-character limit, then you must be having problems with MMS settings and configuration. Some carriers automatically converts SMS with over 160 characters to MMS. If you have an MMS issue on this phone, or if your account does not have permission to receive MMS, then that’s something that only your carrier can help you with.

                      When it comes to troubleshooting this issue, your options are all limited to doing basic software checks like wiping the cache partition, deleting the messaging app’s cache and data, checking the right MMS settings, and even a factory reset. However, before you do any of these things on your end, we recommend that you call your wireless carrier’s technical support team (not the sales/marketing/customer service team) for assistance. There may be some reconfiguration on your account that needs doing.
