Below are specific topics we’re bringing for you today:
Problem 1: Galaxy S6 can’t send SMS
I am an owner of a Samsung S6 and had repairs done as recent as a week or two ago. These repairs as listed in the receipt are for the signal service and what not. The whole screen had also gone completely black (though I could still answer calls by swiping the screen, somehow?). And LED light would still blink showing I had notifications and I had assumed the repairs would be for the LCD screen itself. Now I find my newly fixed device can’t send texts, but it can ring and the call go through. It was working fine up until today when i noticed it when I was home. I’m not sure when it stopped receiving them but so far I’ve turned the device on and off three times and have yet to do a factory reset. — Kiristephens1
Solution: Hi Kiristephens1. Are you having trouble sending text message to just one contact or multiple contacts?
Can’t send to a single contact
If your phone is having trouble sending text message to one contact only, these are the things that you need to do:
Let the contact know
If you’re only having an issue sending SMS to one person, it’s either a network issue or the contact’s device may be blocking your messages. If possible, reach out to that contact via other means (social media, email, voice call, etc) and ask him/her to troubleshoot his/her phone. There’s a chance that he/she may have accidentally tagged your messages as spam, or blocked them by mistake. You must emphasize the fact that you can send SMS to other contacts and everything in your end is working.
Call your carrier and ask for support
Should your contact confirm that your messages are not being blocked, you must then call your carrier to tell them of the problem. There may be a network-related issue that prevents your device from sending to a particular carrier.
Can’t send to multiple contacts
If the phone is unable to send SMS to all contacts, there might be a problem with your device’s Message Center Number. It may be deleted or changed to something different for some reason.
Reinsert the SIM card
Usually, a GSM phone automatically enters the correct Message Center Number after a SIM card has been inserted. If you are in a GSM network using a GSM phone, consider removing the SIM card, then reinserting it to see what happens. Make sure to turn the phone first before removing and re-inserting the SIM.
Check the Message Center Number
Alternatively, you can go to check the Message Center Number right away by doing the following steps:
- Open the messaging app you’re using. (In this troubleshooting, we assume you’re using Samsung’s Messages app).
- Tap Settings icon at the upper right hand side.
- Tap Settings.
- Tap More settings.
- Tap Text Messages.
- Tap Message center.
- Enter the correct Message center number. (Make sure to get the correct one from your carrier).
- Tap Save after entering the correct number.
Wipe messaging app’s data
Should the steps above won’t work at all, make sure that you reset the messaging app’s settings back to their defaults by erasing its data. Here’s how:
- 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 or 7.
- Once in there, look for the application 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.
- Tap Clear Data button.
Do a factory reset
Should all our suggestions above won’t help, do a factory reset as planned. For reference, here’s how it’s done:
- 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 Vol 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 no longer receives sound notifications, only receives them in safe mode
Since the latest update, I no longer receive a notification sound when my text messages are received. They also don’t appear on lock screen or top bar. I have cleared cache and checked phone in safe mode when notifications were restored. How do I know which app to remove to resolve the problem? I have uninstalled a number of apps but obvs not the right one. — June
Solution: Hi June. Safe mode can only help in determining whether third party app is causing a problem or not. However, it can’t tell you exactly what app that might be. To pinpoint the problematic app, you must do a cycle of uninstall and observe. What we mean by that is that you need to uninstall an app, then observe the phone afterwards. If you recently installed an app before noticing this problem, we suggest that you start with it. Uninstall the said app, then observe how SMS notifications work. If the problem remains after removing the app, go on to the next suspect app and do the same cycle. If you have hundreds of third party apps, this can take a while but it’s the only way to go.
Problem 3: Galaxy S6 not showing incoming SMS using Line2 app
I have a Samsung Galaxy S6. I have the app LINE2 installed and using that program for a 2nd business line/text, that myself and my cousin uses. The issue I am having is when I am at work, I can text thru LINE 2, but the texts coming back don’t appear. I contacted Line 2 to help resolve the issue, where I sent them my logs a few times, and even screen shots showing how I am texting and thru their dashboard online, I can see the other person replying, but they are not appearing on my phone. Well they did something after 2 weeks, and NOW the only way I can see them on my phone, is by clearing all the APPS running on my phone. I do not have this issue when I am at home, just while I am at work. But the thing is, this just started now 3.5 weeks ago. BEFORE that I never had the issue. I did the soft restart, and cleared the partition cache as noted on your website. I even took the battery out and held the power button down for over a minute and still no fix.
I also removed a bunch of apps that I no longer need from the rooting. I made sure I did not delete anything then samsung apps that I NEVER use to free up some space. Line 2 thought maybe I did not have enough memory on my phone, but that is not the issue apparently. I am in Windsor, Ontario Canada and my carrier is Virgin Mobile Canada. I doubt that a factory reset will work, as I said it works when I am not at work. I work in a car plant. But again, it worked over 3.5 weeks ago and has no issues until then. So any help or suggestions would be greatly appreciated. If you need any other information, let me know. Thank you. — Joanne
Solution: Hi Joanne. We can only provide solutions for general Android issues. Your situation appears specific to the service you’re getting from Line2 so we suggest that you continue to work with them to fix the problem. Their system is proprietary and we don’t know how it works exactly. From a few bits of information available online, Line2 works similarly to other messaging services like Facebook Messenger, Skype, Hangouts, etc. Basically, the Line2 app uses internet connection in your device to communicate with their remote server, which then processes tasks being requested such as sending and receiving messages or handling voice calls.
We don’t know what their app is doing in your device but it’s possible that it may be encountering coding problems (possibly a compatibility issue) causing it to fail to show incoming messages. An issue like this can only be fixed (or not) by Line2 app developer. This is the reason why we want you to work with them to get it fixed. Hopefully it can get fixed but if not, ask them if there’s a workaround (other than the one you’re doing now).
