S3 Cannot Send MMS

Problem: I cannot send or receive MMC text messages. When compose message with attached (402KB) image, and hit send, see pop-up message “No network connection No signal found for mobile networks” with “OK” button select OK message appears to be sending status shows “sending”, with application-busy cursor twirling around however, message stuck in that status indefinitely (> 1 hour). If I power off/on phone, message status still “sending”, with application-busy cursor twirling around I can send another text message while the MMC message is “stuck”. Ideas? (TIA!)

  • Mobile virtual network operator..: Not set [greyed]

Solution: There are various conditions that must be met for the MMS feature of your phone to work properly. You should have data coverage as well as the correct MMS settings of the carrier you are using. In your case I can see that you are using an unlocked AT&T S3 and the network that you are using is AT&T. On checking on the APN you are using it appears that the settings used is for the Straight Talk network. This may be the reason as to why you can’t send out the MMS.

If you are on the AT&T network then you should try changing your APN to the correct settings. What you need to do is to delete the APN setting in your phone (make sure to take note of the settings first just in case you will need it later) then enter the settings listed below.

AT&T Wap Settings

  • Name: ATT
  • APN: wap.cingular
  • Proxy: <Leave in Blank>
  • Port: <Leave in Blank>
  • Username: [email protected]
  • Password: cingular1
  • Server: <Leave in Blank>
  • MMSC:
  • MMS proxy:
  • MMS port: 80
  • MCC: 310
  • MNC: 410
  • Authentication type: <Leave in Blank>
  • APN type: default,supl,mms
  • APN Protocol: Leave it to the Default one

Try sending out an MMS message once the settings are saved.

If however your phone is on the Straight Talk network then the settings you are using are actually correct. What you need to do is to restart your phone then try connecting to the Internet using your mobile data connection. If you can’t connect then this might also be the reason why you can’t send out an MMS since it also uses a mobile data connection.

In this scenario you should verify first if your SIM has data coverage and also verify the data coverage in your particular area. Once you can connect to the Internet using a mobile data connection then you will be able to use the MMS feature of your phone.

If your phone can connect to the Internet just fine but you can’t send out an MMS then delete the old APN and input it again. Use the following settings listed below.

  • NAME: straight talk
  • APN: tfdata
  • PORT: 80

S3 Keeps On Rebooting, Unable To View Photos On microSD

Problem: Hello, today I was using my phone just like usually, when I arrived home I’ve put it on charge. After I noticed that it was rebooting, and even after it was almost fully charged it keeps rebooting. I tried to uninstall some apps, clearing the system cache partition in the Recovery menu, but nothing. Before trying to do a hard reset, I would like to backup the data on the sd card, but since the phone reboot in about 1 minute after, it is impossible to do something. And not only that seems that it is not reading the files on the sd card. The photos do not show of. I tried to put it on the other phone, but there is a locket on the folder of images. I tried to read the sd card on the pc, but it keep asking to format it. Hope you can help me. Thank you

Solution: If the microSD card isn’t read by another phone or your PC then chances are it is already faulty. One other method that I can think of to retrieve data on this card is to insert it into another Samsung phone if you have access to one. You should also install the latest Kies software on your PC. Connect the other Samsung phone to your PC using a USB cable then run the Kies software. From there you will see an option to back up your data. Proceed with the backup and see if your photos can be recovered.

Another way to recover the photos is if you have enabled cloud synch with the Google Photos app under Google+. If this feature is enabled then you can access your photos from your Google+ account.

If both methods do not work then there’s very little chance of recovering the photos as the microSD card may already be faulty. You might want to try connecting your microSD to your PC using a microSD adapter then try using some of the popular data recovery software available for PC ( such as Recuva) to recover the photos. Be careful though as most of the data recovery software available don’t really work and come with malware. I’ve had some success though with Recuva. Just search on the popular forums and websites on how to properly use it. You could also view this video posted over at YouTube

Regarding your phone rebooting have you checked if the issue occurs when the microSD is removed? The rebooting issue may be caused by the faulty microSD.

S3 Stuck On AT&T Logo

Problem: Hello I have a galaxy s3 and the problem started when I tried to do a factory reset on it, when it tried to restart itself after the reset it just got stock on the AT&T logo. It can stay there all day, I tried deleting the cache from recovery mode but still didn’t work. What can I do? Thank you for your time.

Solution: The reason why it is stuck on the AT&T logo is probably because something went wrong during the factory reset process. Follow the troubleshooting steps below to resolve this issue. Ensure that your battery is fully charged before proceeding.

Reboot your phone

  • Turn off your phone
  • Take out the battery
  • Take out the microSD (if your phone has one installed)
  • Press and hold the power button for 3 minutes
  • Reinsert the battery (leave the microSD out for now)
  • Turn on your phone

If your phone boots up normally then the problem may be caused by some corrupt data stored in the RAM. You can go ahead and turn your phone off now and insert the microSD card.

If rebooting your phone does not solve the issue then try to perform a factory reset again.

  • Turn off the device.
  • Press and hold the following three buttons at the same time: Volume Up key, Home key, 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 data / factory reset.’
  • Press Power button to select.
  • Press the Volume down key to highlight ‘delete all user data.’
  • Press Power button to select and start the master reset. When the master reset is complete, ‘Reboot system now’ is highlighted.

S3 Retrieving Data on Phone That Won’t turn on

Problem: Hello, I came across your page looking for ways to retrieve old files from my old/broken phone. A little backstory, the phone in question is a Samsung galaxy s3 with Verizon wireless. It was thrown from about four stories up and the already cracked screen cracked even more. The phone was also dented up pretty bad. The plastic on the side, by the on button was damaged pretty badly. The device no longer turns on. I might have to get a new screen, but there are some files from the phone I’d like to retrieve which I don’t need the phone to be on (I don’t think). Is there a way to perhaps plug my phone to my computer and attempt to retrieve these files? I am completely unaware of how to do something like this, but was hoping you might be able to help. The phone won’t turn on or even light up with the battery in the phone, but when I remove the battery and plug it into a charger, the red light on the top left of the phone lights up. At this point, anything would help. Thanks

Solution: If your phone hasn’t been used for a long time then chances are the battery has already fully drained or is already dead. There is one way to retrieve data form your phone and that is to connect it to a computer running the latest version of Kies. You can download this software from the Samsung website.

Your phone however needs to be turned on for this to work. You should try to insert a new battery in your phone (one that is known to work and is fully charged). Never mind if the display does not light up at this time. Once the new battery has been inserted connect your phone to the PC (installed with Kies) using a USB cord. Run the Kies software and wait for it to detect your phone. If it can’t detect your phone then try pressing the power switch on your phone and see if it will be detected.

Once Kies detects your phone you can then make a backup of the data stored in it.

S3 Won’t Make or Receive Calls

Problem: Hi, my S3 is 16 months old and has almost stopped receiving and sending phone calls. It is hit and miss but more miss. Rogers says their system is fine and it’s my phone. I think it may have started after the software update. Do you have any suggestions? Wi-Fi works great etc. Texts sometimes does not work as well but it can phone through Wi-Fi Rogers one no problem. Please help. Regards.

Solution: If the problem started right after the software update then the best way to resolve this issue is to perform a factory reset on your phone. The reason why you are facing these issues is that data form the old software version is still present in your phone. This data conflicts with the new software version causing all sorts of issues. The only way to completely remove this old data is to do a factory reset.

Before doing a factory reset make sure that your phone is completely charged and that you have made a backup of all your data.

  • Turn off the device.
  • Press and hold the following three buttons at the same time: Volume Up key, Home key, 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 data / factory reset.’
  • Press Power button to select.
  • Press the Volume down key to highlight ‘delete all user data.’
  • Press Power button to select and start the master reset. When the master reset is complete, ‘Reboot system now’ is highlighted.

In most cases once the factory reset has been completed the issues will disappear.

S3 Won’t Turn On

Problem: Good afternoon. I have a recently purchased Samsung S3, I am however having a problem switching the phone on all day. It just shut down this morning and when I switched it on it didn’t have any of my apps or setting so I restarted the phone and it won’t switch back on. I don’t see how it could be the battery because I’ve had the phone for less than a month. Is there anything you can recommend that might get it started again? I would prefer not to take my phone in for a service if possible. I really appreciate any advice that you can give me to try solve the problem. Thank you.

Solution: When a phone shuts down and does not restart the first thing that needs to be done is to check if whether the battery has sufficient charge. Charge your phone using the original Samsung wall charger then try turning it on. If it turns on then chances are the battery may have just drained. If the time interval between charges is too short then your phone may have several apps and services running which causes the battery life to become low.

To avoid situations where your battery drains quickly you should check what apps and services are running in your phone. Uninstall any app that you don’t really need and turn off the services that you aren’t immediately using (GPS, Wi-Fi, mobile data, Bluetooth, etc.).

If your phone does not turn back on despite charging it then you may have a faulty battery. Try to replace your battery and see if your phone turns on. If it does then your previous battery is the cause of the problem.

If after replacing the battery your phone still does not turn on then this might already be a hardware related issue. In this case you should bring your device to an authorized service center for checking.

S3 Difficult To Charge After KitKat Update

Problem: After receiving the Kit Kat update I’m having difficulty charging the battery.  I have 8 chargers, 2 OEM Samsung with OEM cables that came with both my wife’s and my S3.  None would charge the phone unless you turn it off, pull battery, replace battery, and don’t turn back on until finished charging.  I went to my network service center and they sent it back for replacement.  Received replacement S3 today.  I transferred SIM and SD card from old phone, booted, and get it up and running.  It was charging just fine.  I then installed the Kit Kat update and it’s now having the exact same problem as my original phone.  Any suggestions how to remedy this problem?  I’m traveling for work leaving Sunday and I have to have a working phone for the trip.

Solution: It appears that the problem occurs whenever you update your phone to KitKat. One of the main reasons why this is happening is that data from the previous software version has not been completely removed in your device. This data is causing a conflict with the new software version thus causing this problem. The quickest way to fix this is to do a factory reset on your phone. Before performing this procedure you should backup all your personal data as it will be erased.

  • Turn off the device.
  • Press and hold the following three buttons at the same time: Volume Up key, Home key, 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 data / factory reset.’
  • Press Power button to select.
  • Press the Volume down key to highlight ‘delete all user data.’
  • Press Power button to select and start the master reset. When the master reset is complete, ‘Reboot system now’ is highlighted.

Once the factory reset has been completed the issues you are experiencing should be gone.

S3 Stuck In Boot Loop, Won’t Charge

Problem: My phone has been acting funny for the past week or so.  Won’t hold a charge, and the charge it does take drains VERY quickly.  Today, however, the phone shut down on its own and would not reboot.  It goes to the Samsung icon screen and then would go immediately to black screen.  I tried a factory reset, but when I got to that screen I was looking at a ‘dead bot’ with a red exclamation mark above it.   I’ve tried the factory reset and the system reboot from the same screen. I now get to the homescreen for about 4 seconds, then it shuts down again.   The setup wizard attempts to start and then the phone just powers off.  The phone has no damage…. physical nor water.   Oh, also, it’s showing a full 100% charge, but when it restarts itself it shows an empty battery icon on the screen before it goes to black screen.   I need this fixed asap, please help! Thank you in advance!

Solution: The first thing to consider in this scenario is to replace the battery with a new one. There are instances when this issue occurs if the battery is already faulty. When getting a new battery always make it a point to use an original Samsung battery.

Once the new battery is inserted in your phone leave it charging using the original wall charger for around 2 hours. Try turning on your phone. If the problem is related to the battery then your phone should turn on normally.

If it still displays the Samsung screen then go black then proceed with the following steps below.

  • Turn off your phone
  • Remove the battery
  • Remove the microSD (if one is installed)
  • Press and hold the power button for 3 minutes
  • Replace the battery (don’t insert the microSD yet)
  • Turn on phone

If your phone turns on normally then the problem may just be caused by corrupt data in the phone’s RAM. You can now insert your microSD.

If the problem still occurs then you will need to connect your phone to a PC with the latest Kies software installed. Using a USB cord connect your phone to your PC then run the Kies software. Turn on your phone. Once your phone has been detected backup all of its data then attempt to recover the firmware. You may need your device model name, S/N number, or IMEI number in order to proceed. This information can be found on the label underneath your device battery.

  • Open Kies and click Tools > Firmware Upgrade and Initialization.
  • Enter your device Model name and click OK.
  • Enter the device S / N number and click OK.
  • Kies will verify that the feature is available for your device. If the feature is available, click OK to continue.
  • The firmware version is displayed along with a note that the information on your device will be permanently deleted during this process. Click OK to continue.
  • Follow the steps to prepare your device for emergency recovery. Mark the checkbox next to I have read all of the above information. Select whether you agree to share this update with Samsung. Connect your device to Kies when you have activated the download mode. When your device is in download mode and connected to Kies 3, the Start upgrade button is available. Click Start upgrade to reinstall the firmware.
  • Touch Create backup to create a copy of selected items before proceeding. Touch Skip backup to proceed without backing up any items.
  • Kies 3 will download and prepare your system to update the firmware. This process can take some time. The time will vary based on your network and computer capabilities.
  • Respond to any security warnings about installing software.
  • The progress screen is shown during the upgrade process. The process will take several minutes to complete. Do not disconnect your device, turn the device off, or turn off your computer during this process.
  • Click OK when the upgrade is finished.

S3 Mobile Data Randomly Turns On

Problem: When my phone screen locks, the Wi-Fi will disconnect and 4G will turn on. When I unlock, it takes a second to connect to the Wi-Fi again, but the mobile data stays on. My device was manufactured without a stock mobile data toggle, so I’ve tried Data ON-OFF by Antonio La Rocca, Juice Defender, and a few other mobile data toggle widgets but to no avail. When I lock and then unlock the screen again, the 4G will just come back on. I have the Connections Optimizer unchecked, Wi-Fi is set to never sleep, Wi-Fi power save mode is off via the dialer code but NOTHING WORKS. It seems like a very recent problem, I’m not sure if it has to do with updating the Connections Optimizer (which I removed all updates for) but I would like to fix it. I just don’t want to have 4G turning on all the time when I don’t need it to. Also, I don’t want to just switch to Airplane Mode because I still need to text and make calls, just don’t want 4G at work when I can use their Wi-Fi.

Solution: Try going to Settings -> Connections -> Data usage -> Menu button -> Restrict background data. You could also uncheck “Auto sync data” from here.

S3 MicroSD Card Not Saving Photos

Problem: When I got my S3, the guy at Sprint set it up wrong so I lost half of the pictures on my SD card. But now none of my new pictures will save to it. I’ve tried switching on the camera app to save the new pictures to the SD card and I have tried copying them from the My Files app. Anyone have any advice? I don’t want to lose anymore pictures! Thank you!

Solution: It looks like you may already have a faulty microSD card. Take it out from your phone and using a microSD adapter connect it to your PC. Browse the contents of your microSD from your PC and copy the photos to a new folder in your desktop. Once you have copied everything reformat the microSD card (be sure to uncheck the quick format option). After the format has completed reinsert the microSD on your phone. If it still does not save photos then replace it with a new one.
