Problem #1: Galaxy S6 “Unfortunately, Messages has stopped” error

I am having trouble with my phone for several weeks. I brought it in to AT&T to have it looked at, called Samsung support and brought it in to the Samsung rep at Best Buy. Initially, the phone just started turning off and on without rhyme or reason. We tried everything and it didn’t help. Then it started working for about a week, then started again. I keep clearing the cache.

Now, I am just having trouble with text messages. I receive the error message “Unfortunately, Messages has stopped.” I uninstalled the DirectTV app, which was my only new app. I thought the problem resolved, but only for a few moments. I have rebooted multiple times and cleared the cache. Nothing seems to work.

Your troubleshooting tips suggest removing the battery before sending this form, however I have the Edge S6 Active with no ability to remove the battery. I would really like to resolve this problem ASAP, as I have about 25 text messages that I am unable to view. Some are work related! Please advise as soon as you are able. My phone does work, so you could always call. I’m at my wit’s end here. Thank you in advance. — Toni

Solution: Hi Toni. You said you brought the phone to AT&T and Samsung. So, what did they tell you? Having checked the phone physically, they are in a much authoritative position to tell you what needs to be done for this case. You should have followed whatever they told you to do. Advices of armchair technicians like us are limited to whatever you tell us as far as device history and symptoms are concerned. This means that the solutions we provide also depends on the symptoms and problem descriptions you give us, which may not be enough to actually go to the root of the issue. The “Unfortunately, Messages has stopped” error suggests that the messaging app you’re using may be buggy and no longer works normally. The bug can be due to another app, an operating system level glitch, or some unknown software issue.

Boot the S6 to safe mode

To check if a third party app is to blame, restart the device in safe mode first. Once the phone has booted to safe mode, all third party apps and services will no longer run so if one of them is the culprit, the issue won’t occur. To boot to safe mode, follow these 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.
  • Observe the phone for at least 24 hours.

Safe mode won’t track down the responsible app so you must invest some time in identifying it. This can be done by uninstalling all third party apps one by one. Make sure to observe how messaging app works after each uninstall. If it works fine after removing a particular app, that app is the most likely cause of the error.

Delete the cache partition

If you’ve never tried this before, we also recommend that you do it, especially if booting to safe mode won’t help. Sometimes, system updates and app installations can corrupt the system cache, resulting to other apps to behave erratically. By wiping the cache partition, you are forcing the phone to build a new cache. If the cause of your phone error is a corrupted system cache, this procedure will help. Here are the 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.

Delete cache and data of the messaging app

Should the two procedures won’t work at all, you have no other choice but to wipe the cache and data of the app in question. Tapping on Clear Data button however will delete all your conversation threads, including  the ones you haven’t read yet. If you can, try to create a backup  of all your SMS first before you perform this step. You can use Samsung’s Smart Switch app for the job. Once you’re done wiping the app’s cache and data, you can simply re-sync your messaging app with Smart Switch to get the messages back.

Now, these are the steps on how to delete the cache and data of the app:

  • Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  • Navigate down to “Apps.” This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6.0.
  • Once in there, look for the messaging app you’re using and tap it.
  • You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
  • You should now clearly see the Clear Data and Clear Cache buttons for the application.

Problem #2: Galaxy S6 Bluetooth drains battery faster

Hello. My Samsung Galaxy S6 has been working properly up until a month ago. Ever since i got my new vehicle, everytime i connect my phone via Bluetooth it seems to run up my battery usage consistently through the whole day. Even after my phone is disconnect from the bluetooth and the bluetooth is turned off it still consumes much more battery than normal. I have done multiple tests across a few days and everytime i did not connect anything via bluetooth i did not have a battery issue. It only appears to happen after i connected it once a day. For example, i connected my phone and after disconnecting it, turning off bluetooth, closing any applications using the application manager, and turning on power saver mode, i went through 80% of my battery in just 2 hours. If i do not connect it, it lasts the whole day. What could be causing this issue? — Kevin

Solution: Hi Kevin. There may be an unknown software bug in the system. Try wiping the cache partition of the phone first, then observe it again for some time. Refer to the steps above.

If a fresh system cache won’t make any difference, the next step is doing a Force Stop on the Bluetooth app. Depending on the state of the app, Clear Data button may also be available so you can also do that. Doing any of these two may hopefully disrupt the cycle that happens everytime the app is turned on and off. See to it that you observe the phone again for a few days after you Force Stop or Cleared the app’s data.

Finally, if that will not lead to anything positive, do a factory reset. This will not only reset all software settings back to their known, working state, but may also eliminate an OS-level bug that causes the problem. For reference, below are the steps on how to factory reset your S6:

  • Turn off your Samsung Galaxy S6.
  • 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 #3: Accidentally dropped Galaxy S6 won’t turn on when not connected to charger

I dropped my phone yesterday, not in water, but just on a hard surface and now it will not come on. Charge up or function without it being on the charger. It only comes on when I use the down volume, power and home key together. When on, it shows 48% or some other number as the charging percentage, then it goes backwards to 0% within 2 or 3 minutes. If you remove it from the charger is completely shuts down. If I leave it on the charger it is fully functional. I can listen to my music, text, play games, etc. Please help my warranty just went out and of course I didn’t get insurance for the first time on a phone. — Latrice

Solution: Hi Latrice. If this problem started happening right after you accidentally dropped the phone, the cause is most probably hardware in nature. This means that there’s nothing much that you can do on your end to fix (unless you have the expertise and tools to open the phone up and diagnose hardware problems). The drop may have damaged the motherboard or the battery, which now results to the issue you’re having. There’s no point doing any software troubleshooting in this case; there’s no amount of software tweaks that you can do to fix your problem. Even if the manufacturer warranty is up, we strongly recommend that you bring the phone to a Samsung service center. You will still be paying almost the same amount to a third party repair shop so why not just let Samsung guys do the job.

Problem #4: Sprint Galaxy S6 won’t connect to T-Mobile mobile data in Nevada

My Samsung Galaxy S6 has been unlocked about 6 months ago. It’s originally a Sprint device. I was able to use the phone all this time with prepaid SIMs. Now that I have gotten the phone connected to another provider (T-Mobile), it doesn’t work the same. The first month it worked fine. Then, while relocating to another state (Texas to Nevada), the data was not working when I arrived at Nevada.

Somehow I figured out how to get the voice to work again but the data will not connect to the T-Mobile network. I made sure wi-fi was turned off and data network on. Phone works with wi-fi though.

Tried troubleshooting with T-Mobile and they cannot find out why it won’t connect. They even tried a new SIM and had the same result. I did notice something about the phone when I got it unlocked the first time though, but didn’t think nothing about it since the phone was working fine. A pop up would appear letting me know the phone needed a Samsung software update installed. After I would try to update it, it would give me an error stating “update not successful…error 7.” This message appears everyday once in a while. Could this be the problem? I tried a master reset and still had no success. I can make call but still cannot connect to T-Mobile data network. PLEASE need help! — Bea

Solution: Hi Bea. We are not sure if the “update not successful…error 7” is a Samsung error or Sprint software error. There seems to be no official or unofficial reports about it anywhere. If a master reset did not do anything and all APN settings are correct, the problem might be something you can’t do something about — frequency band. It’s possible that T-Mobile frequency band in your area in Nevada is non-existent or very weak. For example, if your Sprint phone is only capable of connecting to LTE Bands 25,26, and 41 and the T-Mobile in Nevada only transmits in Band 2, 4, and 12, you’ll never be able to use mobile data on this phone. To see if this is the case, use Google to search for the operating frequency band of your phone (use the model number). Once you have the complete operating frequency bands of your phone, contact T-Mobile and ask them for their frequency bands in your area in Nevada. See to it that you mention your specific location or city so they can give you accurate answers. If their operating frequency does not match with your phone’s frequency bands, you’re out of luck. A designated frequency band in a phone is provided by a specific hardware chip so you can’t change it.

Problem #5: Galaxy S6 can’t access SD card

My phone is unable to access my 8GB microSD card although it is still readable. It says I have 2.6GB free storage left. I can still see and open the files already found in my card, however I can’t delete, copy, move or rename any of the files in my card nor can I move files from my phone into my card and vice versa. This was never a problem until one day, it happened but I never took it seriously and figured it will go away but it never did. I have tried the basic solutions like restarting my phone as well removing my card and putting it back in, but the problem still persists. I can’t download files directly into my card either. What’s annoying is that there are some apps from the Play Store that I can’t install on my phone because an error message keeps saying that my phone is unable to access my SD card (error code: 18). Please help. — Brittany

Solution: Hi Brittany. Frankly, there’s nothing much in the internet that accurately explains what this Play Store error code: 18 means. We don’t work for Google so we have no idea what to do with this code. Some Android forums did tackle it but so far, there’s no official direction on what to do with it.  Considering your context, the error may be triggered by a bad SD card or an SD card-related issue. It is therefore imperative that you deal with the SD card first.

The first thing that you want to do is to ensure that the cache partition is deleted and refreshed. Refer to the steps above on how to wipe the cache partition.

After wiping the cache partition, try to see if you can create a copy of your files to either a computer or to a cloud service. Given the unreliability of SD cards, we don’t assume you save anything on it that are irreplaceable. It doesn’t take any advanced technical knowledge to know that SD cards can fail anytime so we hope you don’t use it to save something important.

Once a back up has been created, wipe or reformat the SD card using the phone.

Sometimes, encryption can also cause problems with SD cards. If you did encrypt the card before, try to decrypt it then observe how the phone reads it. If you did not encrypt the card, simply skip this.

If the problem remains even after you reformatted the SD card, try using a different card altogether. The current card may be corrupted or damaged for some reason.

If the same issue occurs even with the second SD card, do a factory reset.

Problem #6: Liquid damaged Galaxy S6 won’t boot back up

I had my phone on the dresser and found it drenched in some Moscato that fell over but I didn’t realize this happened until an hour later, when I went to look for my phone. I dabbed the phone dry, not taking it apart and looked at the phone and it was working normal. I was texting and then fell asleep. I woke up hours later and my phone was off. I turned it back on and got a message saying the device turned off because it was overheating. An hour later, another message popped up saying it was going to turn off due to overheating and suggested that maybe it’s because of too many apps open or water damage. So I turned off the phone and took the battery out and the whole inside of the phone was soaked in moscato as well. A tiny sticker above the battery was red, started to peel off a bit. I never noticed it before so I don’t know if that was useful. I dabbed it off and put it in rice over night because that is what was suggested to me.

Today I took it out of the rice and got the same message that it was over heating. So I put it back in. Do I leave it in rice for a few more days? I see questions answered for water damage but not drinking alcohol damage so I don’t know if i should handle it differently. I’ve never had problems with phones and I am not techy so please help. — Bella

Solution: Hi Bella. The main reason why leaving a wet electronic device in rice is to ensure that liquid is transferred to the rice and not stay with the device. Because rice is more common and can sometimes be more handy than dry silica gel (which can be a good substitute too), it’s the most often used material in doing an electronic “first aid.” Leaving your wet phone in rice without fully covering the container though is useless. You have to make sure that the rice and electronic device are inside a sealed container in order for moisture from the phone to move to the rice. The phone must be completely covered in rice and set aside for at least 1 WEEK in order for this to work. The overnight rice exposure you did probably did nothing. The main reason for the usage of rice is to get every last molecule of water from the phone and doing it for a few hours will not help. The process needs a long time in order to be effective.

Of course, it’s also important to let you know that BEFORE leaving a device in rice, it must be thoroughly cleaned with alcohol (70% rubbing alcohol will do but NOT drinking alcohol) to remove any impurities. If you never did this, forget about the rice; doing it is useless.

Anyway, the best thing that you can for now is to bring the phone to the nearest service center so they can clean the phone properly (with alcohol), dry it, and see if works again normally. Keep in mind that liquid damage can lead to multiple issues, depending on the severity of the spill. If a lot of components in the motherboard has become wet, one of them may become permanently damaged.
