Problem #1: Galaxy S5 Active can’t receive SMS when connected to Toyota Sienna audio system

I have a Samsung GS5 Active running Android 5.0. A few months ago we got a Toyota Sienna. I had successfully paired my phone to the car, can listen to music via Bluetooth, use the Entune Apps to listen to Pandora, make calls and texts. Occasionally even emails would pop up on the nav screen. A few weeks ago, texts stopped working. On hindsight, I do not know if this was related to an Entune App update (I think at some point I had to log in to the app again), or something with my phone itself which is occasionally glitch or slow. I can still make calls. My contacts appear to still be in the car system. I have deleted and re-installed the app on my phone. I have un-paired and re-paired to the car. but I still do not have text message alerts on the nav screen. When I go to apps, it asks if I want to set up messaging. I select yes, then a massage pops up on nav screen saying “you may need to operate your device to allow messaging access. waiting for device…..” However, nothing pops up on my phone. I know it had in the past. maybe I selected No one time? how can I get this prompt to show up on my phone again so I can get messages to work? is there a default somewhere I need to clear?

Also recently there seems to be Bluetooth connectivity issues between phone and car. WHEN using Pandora, I occasionally get pauses in music, sometimes I get a message saying I need to have the app running on my phone (which is still open and seems to be running on the phone in the notification bar) or the phone disconnects all together. — TIA

Solution: Hi Tia. Your main question on how to make messages to work again can only be answered if you do troubleshooting on your end. Our straight answer is NO. There’s no way for us to know where the issue may lie. It can be a compatibility issue, it can be an app you’ve installed, it can be your car’s audio system, it can be the operating system on your Android phone, to mention a few. You need to narrow down the possible causes by doing trial-and-error troubleshooting, which also means investing time and effort in identifying the cause. Sometimes, the basic stuff helps while in others, they can be useless. Since we are only covering one area, that is your Android device, our suggestions are focused on that device only.

If you think that the issue lies on your Galaxy S5 device, the first thing that you want to do is wipe the cache partition. This will ensure that the system cache is fresh. Here’s how:

  • 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.

To cover the possibility that you may have installed an incompatible app, you can also boot the phone in safe mode. If messaging works fine when safe mode is on, you must uninstall apps from the phone until the issue is eliminated. Otherwise, just proceed to the next logical solution. For reference, these are the steps on how to boot your S5 to safe mode:

  • Turn the device off.
  • Press and hold the Power key.
  • When ‘Samsung Galaxy S5′ appears on the screen, release the Power key.
  • Immediately after releasing the Power key, press and hold the Volume down key.
  • Continue to hold the Volume down key until the device finishes restarting.
  • Safe mode will display in the bottom left corner of the screen.
  • Release the Volume down key when you see Safe Mode.

The next solution that you should try is more drastic. This is the last potential solution that you can try on your level. Doing a factory reset will wipe everything from the phone’s internal storage so make sure that you create a backup of your important files and contacts before you proceed. For steps on how to factory reset your device, refer to the steps below.

Now, if nothing changes after a factory reset, you must contact the car maker so they can, in turn, let the manufacturer of the audio system know about the problem.

Problem #2: Galaxy S5 won’t send or receive MMS

Hello. I have an issue with sending MMS messages and receiving them. This started happening after my phone was factory reset. I entered the proper APN settings for my MetroPCS carrier and still nothing. Here are the settings i tried:



MCC: 310 (default)

MNC: 260: (default)

APN Type: default

Bearer: LTE

Everything else I left as it was.

Other settings i tried:


MCC: 310 (default)

MNC: 260: (default)

APN Type: default

Bearer: LTE

Both of these settings work for me for everything except the MMS. When i try to send it, it spins for a few minutes and then it just says failed to send. When i receive MMS the picture does not show up, i just get a download button which does not do anything and then it also say like size: 1kb. What should i do?? Everything worked fine before the factory reset. — Dawid

Solution: Hi Dawid. We don’t work for MetroPCS so we can’t confirm nor deny if the values you provide above are accurate. We know though that APN information is posted all over the web, but we still recommend that you  contact MetroPCS for the correct APN details. Doing this is important so we strongly suggest that you do it before doing anything else.

Now, MMS function mostly work when you have a working mobile data connection. If mobile data connection is working but MMS is not, the issue may be caused by something else. Make sure that you try all available messaging apps installed on your phone to see a difference. If you’ve been using the stock Samsung messaging app, try to see if you have the same type of issue when using your carrier’s messaging app or a third party one like Go SMS.

If MMS continues to fail, let MetroPCS know about it so they can help you.

Problem #3: Galaxy S5 reboots on its own when not connected to a charger

I have a Samsung S5 with a power problem.


  • In the morning I can’t always get the screen on. I haven’t looked into it fully. I mention it only because it may have some relation to problem no 2, which is my real issue.
  • After having been to a subtropical swimming pool, in the dry area, so I don’t think water is the issue. When I was there, the phone suddenly stopped and restarted through the Samsung logo, up to the buz, and restarts again. If an external power source is inserted, then there isn’t a problem, I can do all I want, it is stable. If I don’t have any app’s running I can take the external power source away, and all seems fine, but I can’t start an app, then it resets again.


I tried cleaning the contacts of the battery and the power connector with alcohol, but that didn’t do the trick. I even wiped the cache, which of course didn’t fix it. What should I do? should I buy a new battery? Help? — Otto

Solution: Hi Otto. Android troubleshooting follows a simple rule — if software troubleshooting won’t help, hardware must be to blame. This is true in majority of cases that we’ve seen and we don’t see anything that can exempt your issue from this rule. That said, we recommend that you factory reset the device. If that won’t change anything, you must submit the device for a hardware check. Since you have an S5, consider changing the battery with a good one. If that won’t help either, have the phone repaired or replaced.

For reference, these are the steps on how to factory reset you device:

  • 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 #4: Galaxy S5 drains battery very fast | Galaxy S5 won’t charge properly

Hi, I have a strange problem that happened last night. I searched online but it seems that my issue may be I went to bed, plugged my phone into the regular Samsung wall plug and cord. It was great for a few minutes but then it beeped and it seemed to disconnect from the power supply. I checked the phone and there was no lightning bolt in the battery icon. I changed charging cords and still nothing. I tried plugging it into my laptop and my laptop could not discover it, even with Kies.

Another twist, lol. I found that after the phone had been plugged in for a while it will charge but the display for % of a charge will not change until I will change downward though as the battery discharges. Finally, I did try the reboot, taking battery out, clearing cache and even did a factory reset.

Also, when the phone is powered down and I plug it in it will show the charging icon for about 30 seconds then it switches to a battery with a yellow triangle with an exclamation mark in it. Hope this was not to confusing, I am very frustrated. — Fastdriver_0

Solution: Hi Fastdriver_0. the first thing that you want to try here is to recalibrate the battery so you can teach the operating system how to gauge the battery level properly. To do that, follow these steps:

  • Use the phone by playing games or doing tasks to hasten power discharge, until the phone turns itself off.
  • Turn the phone on again and let it turn itself off.
  • Charge the phone without turning it back on.
  • Wait until the battery says it fully charged to 100%
  • Unplug the charger and turn the phone on.
  • If the phone says it’s not 100% anymore, turn it off, plug the charger back in and wait until 100% charge is reached.
  • Unplug the charger the turn the phone on again.
  • Use the phone until you drain the battery down to 0.
  • Repeat the cycle once.

Observe the phone again for a few hours while charging it. If it remains problematic, do a factory reset. Refer to the steps above.

You can also try to change the battery with a known working one. If battery is the only issue, replacing the existing one should give easily fix the problem.

Finally, if factory reset or a new battery won’t change anything, you can assume that the phone may have been damaged. Find a way to have it repaired or replaced.

Problem #5: Downloaded photos to Galaxy S5 have poor quality

Hello, Thanks for your forum. I am operating a Samsung Galaxy S5 and actually doing some travelling in India. I had a Vodafone SIM card put into my phone and am using my phone as a mobile hotspot to run the internet on my computer with. I am running my graphic design business from here currently so it is vital that I am able to download high quality images for the work. I am having the problem that more than 50% of the images that I see and then try to download the image quality gets damaged or downgraded almost as if I saved a JPEG on an image quality setting of ‘1’ or ‘0’. When I was in the states 100% of the images retained their original quality, fyi. Not sure what to do about this to get them back to normal. I have linked image samples below, they show the mottling of the background and the blurring of the image –>Sample 1 –>Sample 2. Thanks again for any advice, Regards. — Jonathan

Solution: Hi Jonathan. The reason for the problem may have something to do with the source of the files. If you download images from social networking sites like Facebook, Google Plus, Twitter, etc., you can expect to receive poor copies of photos as these sites converts uploaded files into compressed ones, sometimes significantly degrading the quality.

Try to download photos from third party hosting websites that offer lossless compression to receive better copies of images. Imgur can provide lossless compression to any photo as long as it doesn’t go beyond their 5MB file size limit.

Problem #6: Slow mobile data connection on Galaxy S5

Goodday, i realized when i had put service onto my phone that even though the data was successful my phone was not able to connect using the data plan. and so i saw the tip about entering in the APN for the phone service you are using which i found out and adding into the phone, now it worked for like one day. it was around night time i entered it and it’s night time again now and it seems that my phones service no longer works. i checked and i didnt run out of service and now once again it isn’t working. i tried changing the network mode from Global to LTE and the other features, however still nothing. the letter above the signal bar changed from H to E and I’m still having no service. — Biggiethebear

Solution: Hi Biggiethebear. There are two possible causes for your problem here. First, is the strength of your network’s signal. If your area is far from the your network’s tower, if your house is surrounded by objects that can interfere with cellular signals like trees, tall buildings, or thick walls, you can’t expect good reception all the time. Poor signal reception translates to slow or unreliable mobile data connection, resulting to poor browsing experience on your mobile device. If you think there’s poor signal reception inside your house (as indicated by fewer cellular signal bars on the status bar), make sure that you talk to your carrier so they can help you. If you’re willing to invest in additional hardware, and if your carrier does offer it, they can install a signal boosting device in your place to improve coverage.

The second reason for the problem is the type of network in your location, or the one you have selected in your device. As you can see, changing the network type can significantly affect the speed of your data connection. For example, changing the network type from 3G/H to 2G or E is not recommended. 2G is much slower than 3G and 3G is slower than 4G or LTE. Talk to your carrier what’s the ideal network type in your area to use and make sure that you stick to it. Don’t change any network setting (or anything, really) if you are not sure what you’re doing.
