Problem 1: Galaxy S6 takes a long time sending MMS, mobile data connection is slow

On my Galaxy S6 I have always had problems sending a text message with a picture or a video. I’ve had to resort to uploading the video to YouTube in order to send it and even wait a long time to even send a picture. I have contacted Verizon and been told different things but nothing works. I have to use Wi-Fi because despite the fact I have the fastest speed internet and a network extender I still drop calls.

Also I just did a software update and now in the text messaging application instead of displaying the autocorrect it shows a dark rectangular box which is difficult to read want to suggested correction is. Is there any way to lighten it up or display it in another form to make this process easier to see? I can click and long press the Box and it brings up the correction in Orange but it doesn’t always work properly and is time consuming. It is probably the same in emails but I haven’t even checked that yet. This software update has been pretty extensive and changed a lot of things and I’m still learning how how to operate it efficiently. — Dalemiller2971

Solution: Hi Dalemiller2971.

First of all, Verizon’s network extender is not meant to improve mobile data connection, which is most probably 4G LTE. A network extender is designed to enhance voice calling and 3G data coverage only. Since your problem has something to do with mobile data, which again, we think is 4G LTE, uploading videos can still take time to complete. This can also be the reason why sending MMS sucks.

For your MMS problem, there are a number of things that should be clear to you.

  • One is the fact that this type of service needs mobile data connection. If Verizon’s mobile data service in your location is poor, you really can’t expect to send/receive MMS and upload videos normally.
  • Second is the fact that this situation is not a problem at all. That means there’s no problem with your phone but rather with the quality of service you receive from your carrier. No third party support time like us can help you with it.
  • Third is another fact that you’re a paying customer. Verizon is obligated to help you get to the bottom of the issue. Make sure that you work with them to find out if there’s something that they can do to improve the speed of your mobile data connection. If they’ve already did that and you’ve already been told that there’s nothing more that they can do due to, say, the remote location you’re in, believe them. If you are unlucky to be located in an area where it’s technically impossible to improve the signal, you can either accept that, or simply switch carriers that can offer better service.

Secondly, your drop calls issue may still be related to the poor signal reception theory we’ve been telling you. Again, work with Verizon to find where the problem lies. Sometimes, in our desire to make things work out our way, we can be unreasonable when carriers tell us the real deal. Try to be open and hear what they’re saying. Voice calling and SMS require a number of things in order to work. A network extender, however it’s marketed by Verizon, can only help so much. If this problem has been happening for a long time now without apparent solution, there’s probably nothing much that Verizon can do to fix it. It’s probably a good idea to start looking for a different network service.

Thirdly, we don’t know what messaging app you’re using. If it’s the default Samsung app called Messages, there’s no option to change the color of anything in it. We suggest that you try to change the phone’s display settings (Settings>Diplay) or the themes (Settings>Wallpapers and themes).

If you’re using a third party messaging app or Verizon’s own messaging app, try to go under its settings and see if you can tweak some things relating to font color and such.

Problem 2: Sprint Galaxy S6 incoming SMS are being received by another phone

I have an Android S6 and my husband has an iPhone both about a year old. Within the last four or five months my husband has been receiving text meant for me and replies meant for whoever texted me.

Also, whenever I send a multimedia message, a picture, it goes to the recipient under his telephone number instead of my telephone number. How could that be? And how come he is getting my messages? I’m with Sprint. Thank you. — Cindy

Solution: Hi Cindy. There may be a mixup with how your line and that of your husband are set up. If both lines are part of a certain plan, like a Family plan, make sure that you call Sprint so they can figure out how to fix it. This is not a device issue so there’s no need to troubleshoot your phone.

Problem 3: Galaxy S6 ringtone is stuck, can’t be changed

I was using my phone one day and the ringtone was working just fine. I got a message from one of my friends and instead of playing the ringtone it played the sound when you increase your volume. I turned my phone all the way off and reset the ringtone, but it still does it and now it is doing for every notification. It just plays the sound when you increase your volume. I don’t like having my phone on vibrate all the time because I like hearing the ringtones. When someone calls it makes the same noise, does not play the ringtone. — Zephaniah

Solution: Hi Zephaniah. We really can’t say what’s going on here but if you have a third party app like Zedge or similar that can control or override system audio settings, be sure to remove it and see what happens.alternatively, you can also restart the phone in safe mode and see how sound notification works. While in safe mode, all third party apps and services will be suspended. If sound notification works normally in this mode, that’s a confirmation that one of the third party apps is the cause.

If nothing changes even when the device is in safe mode though, consider wiping the phone via factory reset. There may be an operating system bug that prevents audio changes you want from being implemented. To factory reset your S6, kindly do these steps:

  1. Create a backup of your important files such as photos, videos, contacts etc. You can use Smart Switch for this task.
  2. Turn off your Samsung Galaxy S6 Edge.
  3. Press and hold the Volume Up, Home and Power keys together.
  4. When the device powers on and displays ‘Power on logo’, release all keys and the Android icon will appear on the screen.
  5. Wait until the Android Recovery Screen appears after about 30 seconds.
  6. Using the Volume Down key, highlight the option, ‘wipe data/factory reset’ and press the Power key to select it.
  7. 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.
  8. After the reset is complete, highlight ‘Reboot system now’ and hit the Power key to restart the phone.

Problem 4: Galaxy S6 MMS not working due to mobile data problem

My phone is having problems syncing. This has been happening for a few days now. My emails aren’t coming through & text messages with photos are unable to download. My mobile data is on. I was able to get it synced a few times, but it takes a lot of powering off & back on. I have since cleared my cache & wiped my system cache. I’m currently at 16 hours since my mail has synced & am at a loss. Please help! Thank you! — Andrea J.

Solution: Hi Andrea. If you rely on mobile data connection when syncing emails, there must be a problem with your mobile data service at this time. MMS also require mobile data to work so it can be expected to work intermittently if you have a mobile data problem. Make sure that you contact your carrier about this so they can help you. There may be an on-going maintenance or outage in the area affecting users like you.

Problem 5: Galaxy S6 can’t send SMS due to incorrect Message Center number

Hello. I have a Galaxy S6. I purchased a month plan with a SIM card in Austria from Yooopi which was working fine for a couple of weeks but now I cannot send SMS messages when on cellular network. I can do everything else including receive SMS. I called support and they said I had to enter what sounds like some kind of access number, +436640520, somewhere in the settings for SMS messaging but they can’t tell me where to enter it and I can find nothing in settings that asks for a number. Â They were unable to help me. — Kaukafran

Solution: Hi Kaukafran. Your phone must have the correct Message Center number in order to successfully send and receive SMS. We can’t confirm if +436640520 is the message center number but you can give it a try. If you are using the pre-installed messaging app named Messages, here are the steps that you can do:

  1. Open Messages app.
  2. Tap More icon at the upper right hand side (three-dot icon).
  3. Tap Settings.
  4. Tap More settings.
  5. Tap Text messages.
  6. Tap Message center.
  7. Enter the number.
