Problem #1: Verizon Galaxy S6 won’t send or receive MMS on AT&T network
I bought this Verizon “Factory Unlocked” Samsung S6, brought it to AT&T for them to set up the APN information, and everything works except sending and receiving pictures through text, well multimedia text. AT&T stated I shouldn’t be having problems of. It was factory unlocked but kinda blew me off. I asked if all factory unlocked phones were unable to send multimedia text, I was told yes they can but they guess mine can’t was the answer I received.
I pray y’all can help me I hoping I wasn’t ripped off. The seller is refusing the return as of now because I brought it to AT&T (he called it a third party) to activate it.
Thanks for everything y’all do it helps so much. — Kayla
Solution: Hi Kayla. There are a number of reasons why MMS won’t work on a device ranging from incorrect phone settings, bad messaging app, or account- or network-related problem. Your first task is to find out what is causing the issue by doing some basic troubleshooting. Below are the things that you can do:
Ensure that your messaging app inbox has enough storage space left. Messaging apps have a limited number of messages that they can store. If your phone has reached the limit at this time, it won’t be able to send and receive text messages or MMS.
Try to delete as many messages as you can then try to send an MMS to your number.
Check the network connection. Most phones are configured to automatically detect and connect to a network. They are also set to optimize the connection “session” but this process does not usually go as planned every time. You need to manually select a network under Settings to see if the phone is simply not “optimizing” the current connection.
To do this on a Galaxy S6, simply follow these steps:
From the Home screen, tap the Apps icon.
Scroll to Connections, then tap Mobile networks.
Tap Network operators.
Tap Search now.
When presented with a list of available networks, try to select one that is NOT your carrier and wait for the error message.
Once you’ve selected another network, your phone is no longer connected to your carrier and is fully logged off from it.
Try to connect to your carrier’s network again.
Make sure that you have the correct AT&T MMS configuration setup. We know that AT&T representatives have already setup the APN on your phone but there’s still a chance that they may have missed something. Kindly revisit the phone’s APN settings and see if they correspond with the table below.
Check if you have a compatible SIM card. Older SIM cards or those from other carriers may not automatically allow sending or receiving of MMS on AT&T network. If you purchased a new SIM card from AT&T when you brought your phone to them, you can skip this step.
To check if your current SIM card is compatible, please visit AT&T website.
Ask AT&T if your existing data plan is compatible. If you recycled an old SIM card and put it on your new S6, the current data plan may not allow MMS. AT&T needs to update the current device information on your account to let it to send and receive MMS. If you aren’t sure about this step, make sure that you contact AT&T.
Problem #2: Streaming apps (SoundCloud and Google Play Music) on Galaxy S6 not working properly after Marshmallow update | Galaxy S6 cannot send text message after updating to Marshmallow
Data has been choppy, when using any streaming service like SoundCloud or Google Play Music, the song stops and buffers, but when you open the app and stop and start the song, it fixes immediately. I began to see this problem immediately after installing the Marshmallow update. The song keeps stopping within 30 seconds every time, but if the phone is open on the app, it streams normally. It stops when the phone is locked.
Can’t send text messages, this wasn’t a problem until 5 days after I installed the update. Happened suddenly, sent texts the same morning, tried restarting and powering on and off, text messages are received, but cannot send. Tried using your previous guide of deleting network cache, and app cache, didn’t work. — Vineet
Solution: Hi Vineet. The new Marshmallow update, like its predecessor appears to be causing minor app issues at this time. This can be due to a number of reasons and unfortunately, there’s just no way to pinpoint exactly what might be wrong on a certain situation. A good way to start though, especially if there are multiple issues, is to perform a factory reset. If deleting the cache partition or app cache won’t make any difference, resorting to factory reset might prove effective. This is because many post-update issues are caused by firmware glitches.
Perform a factory reset
Major updates that involve replacing one version with another, like the transition from Lollipop to Marshmallow, are usually messy as old system files are not usually replaced correctly, permissions not set properly, among other things. Ensuring that your phone runs a clean firmware after a major update can be done by doing a factory reset.
Factory reset can only do so much. Many users think that updating to another Android operating system automatically updates all their apps. The complete opposite is true. You need to ensure that your apps are up-to-date as well to minimize issues. We know that you’re dealing with official apps from reputed developers here but keep in mind that software issues may not necessarily be caused by a firmware. An app optimized to work with Lollipop may not work properly with Marshmallow, for example. In an ideal world, app developers are supposed to ensure that their products will work with the new operating system but we know that this does not always happen. Outdated apps can sometimes lead to conflicts. Make sure to contact the developers to see if their product is ready for Marshmallow.
Fixing cannot send SMS issue
If a handset appears to have difficulty sending a text message, when it was able to do so before, that’s probably because there’s a problem on the receiving end. Try sending a text to your own number to see if it goes through. If it’s successful, that means that either your friend is having trouble with his/her phone or carrier, or that your own carrier is unable to transmit your text message to another network.
If you are unable to send a text message to your own number though, make sure that you check that the device’s message center number is correct. If the message center number is not configured properly, your device will be unable to send SMS. To check, just follow the steps below:
Tap More settings.
Tap Text messages.
Tap Message Center and enter the correct number (make sure you call your carrier for the correct one).
If changing the message center number won’t work, call your wireless carrier to ask for direct assistance.
Problem #3: Galaxy S6 stuck on loading screen during an update
Dear The DroidGuy. I’ve read a lot on your website about troubleshooting the S6 boot issues and tried them to fix my phone.
My current issue is that, I got the official update through the phone settings and downloaded the new OS. While it was installing (plugged into the charger) it rebooted to the Galaxy S6 Edge screen and got stuck there. Power button won’t do anything, and the phone is permanently stuck on that screen.
Pressing power and volume down do reset the phone but it goes back to the same screen. The only mode I could access is the install mode. I want to keep my data but not sure how or if it’s even possible at this stage.
Please guide me to a solution, appreciate your great work. Regards. — Faisal
Solution: Hi Faisal. Over-the-air (OTA) updates resulting to a situation like yours are few and far between but if they do happen, there’s no effective way to boot back the device to normal mode than by installing a new ROM manually. This means that you need to boot your S6 to Odin mode and install a new ROM (stock or custom) yourself. You can use Google to search for detailed instructions how to do it.
Alternatively, you can call Samsung to help you flash the new firmware on your S6.
Problem #4: How to improve battery life on Galaxy S6 Edge Plus
I bought my Samsung Galaxy S6 Edge Plus about a month and a half ago from a carrier called Tigo. I have used the phone quite a bit and I almost never let it run out of charge, though most of the time it does go quite low: 5%, 7% even two percent.
However, recently my phone has not been able to stand those percents, immediately shutting off or draining the battery down to the point where I run to find a charger as fast as possible. I know this may not seem that much of an issue, but I’m afraid that percentage will rise and soon enough it won’t stand 12%, or even 20%.
Is there anything at all I can do about this? Should I talk to my carrier to have the battery replaced or…something? Do help me, please. — Daniel
Solution: Hi Daniel. The rate of battery drain on your phone depends on a number of factors including the how many apps are running actively and/or in the background, the status of the battery itself (if it’s still working properly or not), screen brightness, etc. The exact reason varies in every case so figuring it out is yours to do alone. We can only give tips that usually work for most Android users. Below are the things that you can try:
Check what apps are sucking your battery dry. The number of apps and services running simultaneously is one of the common reasons for losing that precious battery life fast. Go under Settings>Battery to see a breakdown of the apps and services eating up battery power. From there, it’s up to you how you’re going to create a strategy to minimize the bleeding. For example, if Facebook app stands out as among the top power consumer in your device together with Screen, you may want to lower the screen brightness to the lowest comfortable level while browsing over Facebook most of the time.
If you want to force an app or apps to go on hibernation mode without fully disabling or uninstalling them, consider using third party apps like Greenify. Doing so helps your phone free up resources and improve battery life without removing anything you might need in the future.
Turn off automatic sync for social networking apps. Another reason for your issue may be an unusually high number of apps that update themselves in the background. Online games, social networking apps, shopping apps, and email apps are among the most notorious reasons for fast battery drain issue across many types of smartphones. If you can’t live without mobile data or Wi-Fi on your handset most of the time, make sure that the sync settings of your apps that require to update their contents regularly are set to off or manual.
Consider dimming the screen. As mentioned above, screen brightness can quickly drain any smartphone’s battery. Samsung’s AMOLED screen is beautiful to behold but is power hungry. If you’re used to using the phone’s screen in full brightness, we say that you sacrifice a little comfort if only to save battery power.
Turn off unnecessary services. The Galaxy S6 is equipped with many services that makes our digital world a bit more comfortable at a cost of battery life. Make sure that you customize options and features that will help conserve battery power. Among the things that you can try are the following:
Discontinue use of Live wallpapers.
Turn off the Bluetooth® feature.
Turn off Wi-Fi®.
Turn off the GPS service.
Turn off the Smart features.
Decrease the backlight time (timeout settings).
Decrease the brightness of the display, or use Automatic brightness.
Turn off haptic feedback.
If the “percentage” continues to rise after doing our battery life improvement tips, there may be some hardware error behind the trouble. If your phone is still covered by a warranty, kindly call Samsung for repair or replacement.
Problem #5: Galaxy S6 display won’t turn back on after charging port was replaced
Hi. Ok this is my phone story. It’s been like a couple months that when I charge my phone on the power, I sometimes need to Giggle the cable at the charger port on my phone. Sometimes I wouldn’t need to, but with time, it became frequent till the day I’d ALWAYS need to do that.
Then it came to the point that my phone couldn’t charge again. i tried different cable, for sure the problem came from my phone. There was nothing wrong at all anywhere else then the charging thing, screen worked fine etc.
I took it to a phone repair place to fix it, they tried to change the port, and battery, since then screen wouldn’t work anymore!!! We picked it up without it being fixed unfortunately and when I plugged it on power, it would charge just fine, no need to giggle the cable in the entry port, now it’s just the screen. I see the red light showing its charging, when i try to turn on the phone, i can tell it does respond cause of the vibrator BUT no display at all.
Thanks for your help. — Hinata
Solution: Hi Hinata. If the screen issue happened after the repair session, your best option is to bring the phone back to the repair shop to have it fixed. Unless you want to replace the screen yourself, there’s just nothing that we can tell you that will fix it. No software troubleshooting can repair a broken display.
Problem #6: Galaxy S6 Home button stopped working, notification bar not showing, unable to install or uninstall apps after Android update
Hello. I have a Galaxy S6. I was prompted to update my system. Once the update was complete a lot of things stopped working. I no longer have access to the notification bar, the home button stopped functioning, the background went completely black, I cannot install or uninstall apps, and am also receiving the error messages “System UI has stopped working” and “Package Access Helper” has stopped working.
I also have a cracked screen and applied for the insurance replacement, which I received, but I have to return the old one. This wouldn’t be an issue, however I need to get the data off of the old phone that I have had for 2 years.
I don’t have a lot of tech experience, but I am really good at following instruction, as long as it is detailed. I know that it might be a little more work for you all to help me, but I would be eternity grateful. I have read a lot of articles trying to find and solution and I think I found one. I think that if I could install the app Helium that I could backup my app data and transfer to my new phone. One: Would this work? Two: How do I get the app to install with the system UI & package access helper error? Can you guys please help? Thank you. — Lisa
Solution: Hi Lisa. We’re sorry to hear about this issue but if your device no longer allows app installation at this time, your only choices to get it back to working order is by doing either a master reset or by flashing a stock or custom ROM. Both of these procedures involve wiping the internal phone storage.
If you have a computer, try to connect your device to it via USB and see if it detects it. If you’re lucky, you may still be able to move your phone data to your computer before doing a factory reset or ROM installation.
