Galaxy S3 Can’t Connect To Mobile Data Network

Problem: Hello! I was hoping you could help me solve my phone issues. Ever since the last update – 4.4.2, it will no longer connect to a mobile network. It says no connection found when I try to go online or check email. I spoke with boost (after many many hours of clicking buttons on the phone) and was told nothing was wrong with my phone and that I am in an excellent service area. Under mobile network, the box is checked,  but it doesn’t work. I also can no longer send or receive picture texts. Thank you for reading my message. I look forward to your reply oh wise droid guy 🙂

Solution: What you need to check first is your mobile data settings and see if you are using the correct ones. Go to your mobile network settings and verify these settings.

  • APN enable/disable: APN enabled
  • Bearer: Unspecified

If something is not right then edit the particular field and correct it. Reboot your device normally then check and see if you can connect to your mobile data network.

If you still can’t connect then try to delete your APN and MMS settings then go to the Telstra Mobile Phone Setup page where you can have the settings sent to your device OTA.

Once you have saved the new settings try to check if you can access the Internet or send out an MMS. If you still can’t then perhaps there is a third party app that is blocking your device from connecting to your mobile network. If so then you will need to uninstall that particular app.

To check on this boot your device in Safe Mode.

  • Ensure the device is powered off.
  • Press and hold the Power button until the Samsung logo appears then release.
  • With the Samsung logo on screen, press and hold the Volume down key.
  • Continue to hold the Volume down key until Safe mode appears in the lower-left of the unlock screen then release.

Galaxy S3 Email Issues After KitKat Update

Problem: Hi. Following a firmware update on 6/28/14 (kitkat) on my s3 I have been unable to receive emails via optonline. I can, however send email via optonline as well as send and receive via gmail. Any assistance would be greatly appreciated. Thank you.

Solution: First check and see if you have enabled auto sync on your device. Go to > settings > connections tab , then “Data Usage” , then click on hard menu button (bottom left) of phone-check (tick) Auto Sync data. Now try sending your optonline account an email and see if you can receive it.

Try to check also if you have the correct Incoming mail settings. This should be mail.optonline.net or mail.optimum.net depending on your account with port number 110.

Galaxy S3 Screen Goes Black In Google Maps

Problem: I enjoy your newsletter and you have helped me some many of the “problems” with the upgrade on the Samsung Galaxy III. I hope you haven’t covered this issue already but I can’t seem to find it. I love my phone but after the latest upgrade (4.4.2), when I am using driving directions in Maps on my phone (phone plugged into the charger) the screen on the phone goes black after ~ 10 minutes. It will come back on if I touch the screen some of the time but mostly I have to re-start google maps; very dangerous when I am driving. Is there a simple fix or should I install an app (Caffene?) to get around it. Thanks in advance!

Solution: First we need to check if this issue is caused by a third party app that’s interfering with the screen timeout. Boot your device in Safe Mode.

  • Ensure the device is powered off.
  • Press and hold the Power button until the Samsung logo appears then release.
  • With the Samsung logo on screen, press and hold the Volume down key.
  • Continue to hold the Volume down key until Safe mode appears in the lower-left of the unlock screen then release.

Once in Safe Mode try using Google Maps and see if the issue still exists. If it doesn’t then you will have to uninstall any third party app that you may have recently installed.

If you are still having a problem then you might want to try clearing the cache partition of your device as the problem occurred after you updated it. Take note that this does not delete your personal 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, let go of 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 and wipe the cache.
  • With ‘reboot system now’ highlighted, press the Power key to restart the device.

This should fix the issue of your device not responding after 10 minutes of inactivity.

When using Google Maps as a navigation aid you might also want to try to change the setting of the display to never turn off automatically.

Galaxy S3 Lag Issues

Problem: Hi there, I read your article on saving memory on the Samsung Galazy S3, I noticed another issue on my S3, there seems to be a 3 sec lag when I open contacts on my S3, feels like it takes forever to open in emergencies, is there any way I can fix this lag?? Any request would be grately appreceated.

Solution: When a Galaxy S3 is experiencing lag issues then one of the main causes of this is not enough RAM. There could be lots of apps running in the background that are using system resources and slowing your device down.

If in your case it is only the Contacts app that is lagging then you might want to clear its cache.

  • Go to Settings
  • Click Apps
  • Go to All Tab
  • Search for Contacts
  • Click on Clear Cache

Now try opening the Contacts app and see if it is still lagging. If it is then try booting you device in Safe Mode (instructions in post above) and check on the Contacts app from there. If you are not experiencing any lag problems then you may want to uninstall third party apps which you don’t need.

Galaxy S3 Photos In SD Card Disappear

Problem: Hi, I was hoping you could help me out with this problem. Recently pictures that I have taken with my phone camera and saved to my memory card are disappearing. Sometimes right away sometimes a week later. First when I open my gallery (i use quick pic) everything seems okay. Then the next time I’ll notice a fewif the more recent pictures day fail to load but some will show up. Then eventually all the recent pictures just disappear like they were never there. I’ve check different forums and haven’t been able to find a solution. I checked hidden folders, checked file manager, restarted my phone nothing seems to work. Any help would be greatly appreciated. Phone is Samsung s3, latest android installed 4.4.2, 64gig sd card, never had an issue with it for 2 years. Thanks

Solution: What we need to do first is to isolate the SD card and see if it is the cause of the problem. Try using a new one ( if possible a different brand) and observe if the problem still occurs. Usually when an SD card becomes faulty it does not work properly anymore and it’s possible that it may not be able to store data properly.

If after replacing the SD card the problem still exists then we now have determined that the phone is causing it.

We start by checking if any third party app is causing this issue. Boot your device in Safe mode then observe its operation again. Take photos and see if your photos disappear. It may take a week for you to perform this step since the issue seems to be random. If you have determined that you are no longer losing photos then a third party app may be causing this in which case you must uninstall it.

Galaxy S3 Screen Black But Notification Flashing

Problem: I have a calculated s3 and have had it a long time now and it didn’t start doing this till the other night. Basically I always put my phone on silent and on charge before I go to bed even if it’s got 97% battery life so I will wake up to a full battery over the last few days I wake up grab my phone and the little notification light will be blinking either blue or yellow or it will still be green which means full charge. I unplug it and hit the unlock button and nothing happens I tried the home button still nothing. I can hit them over and over and still nothing I tried holding them both down for twenty seconds nothing. So I pull the back off and rip the battery out and restart it only problem is I’m losing my notification when I do that. I had a couple missed calls and a text the other night I know for sure but when I turned the phone on they were not there I know I was supposed to though because who sent them told me. Please help this is truly frustrating.

Solution: When your device freezes it could mean that there is an issue with its software and you may need to do a factory reset to restore it to its original condition. Before doing this procedure though you will have to backup all of your data stored on the device as they will be erased.

  • Turn off device
  • Simultaneously press and hold the power button + volume up button + home key until the Samsung logo appears, then release only the power button. Release the volume up button and home key when the recovery screen appears.
  • From the Android system recovery screen, select wipe data/factory reset.
  • Note Utilize the volume up/down keys to highlight and the power button to select.
  • Select Yes — delete all user data.
  • Note Allow several seconds for the factory data reset to complete.
  • Select reboot system now.
  • Note Allow several minutes for the reboot process to complete.

This should help solve the issue you are facing with your device.

Galaxy S3 Sensitive Power Button

Problem: I’ve been reading your post about the problem after updating the OS on the S3, however this issue doesnt have to do with an update I believe. The issue I am having is the power button is hypersensitive,  it is sensitive when I have a case on it and when I dont. It is so sensitive that I just have to brush my finger near the button and it activates the button, this can be very annoying when I put it in my pocket since it is constantly restarting due to the button being pushed. What can I do about this?

Solution: Several Galaxy S3 owners are also complaining that their power button has suddenly become super sensitive. From what you mentioned it appears that this could already be a hardware issue. But just in case let’s first check the software side of your phone. While still turned on remove its battery and leave it off for 10 seconds. Replace the battery and turn your device on. Check on the power button and see if it works normally. If it is still sensitive try booting your device in Safe Mode to check whether a third part app is causing this.

The final checking that you can do on the software side is to do a factory reset. Before doing the procedure make sure to backup all your data first.

If after thoroughly checking the software of your device and the problem still exists then this could already be a hardware issue. In this case you will have to bring your device to an authorized service center for checking.

Galaxy S3 Overheating Error

Problem: Hi there, This is the message I’m getting:  Unable to open this application. Your device is overheating. The phone will allow me to make calls and text and send and receive emails, but when I try to open up any other application (camera, internet, games, etc.) I get the above message.  I’ve rebooted a few times and tried removing and replacing the battery.  I don’t think it’s really overheating: it’s not in the car and it doesn’t feel warm to the touch. Any suggestions?

Solution: One of the main causes why the S3 overheats is that the processor is doing a lot of work. To make sure that your device does not overheat try uninstalling apps that you don’t really need. They may be running in the background and using unnecessary system resources. Next, turn off the services which you are not using. These includes, Bluetooth, GPS, and mobile data if you aren’t using them. Also, try to get a new SD card. Old SD cards tend to contain a bunch of data that’s not really needed and when your phone access the card it will take more processing power to find the needed data.

Try also to boot your device in Safe Mode and see if the “Unable to open this application. Your device is overheating” error message still pops up. If it doesn’t then this is most probably caused by a third party app in which case you must find out which app it is and uninstall it.

Galaxy S3 Does Not Turn On

Problem: hi, i brought my samsung galaxy s3 about a year and a half ago. i used it for a few weeks before packing it up and putting it away due to going back to using an iPhone. I gave it to my daughter tonight due to her needing a phone urgently but it will not turn on at all. charged it for hours and still nothing. do you have an ideas on how i can get it working or even tell me whats wrong with it? its practically brand new and shouldn’t have these issues. thanks.

Solution: The first thing to check is the battery and charger. Try using a new battery and a new wall charger and see if you could turn on your device. If a battery or charger is faulty then there’s a huge possibility that you won’t be able to turn on your device.

If you are not getting any response at all from your device like a notification light that it is charging then try connecting it to a laptop using a USB cord. If it doesn’t respond at all then you might want to bring your device to an authorized service center as this may already have a faulty hardware.

Galaxy S3 “unfortunately system ui has stopped”

Problem: Hi, My Samsung galaxy s3 is only 9 months old. On Wednesday 25th June 2014, I was just browsing when I got this message pop-up: ‘unfortunately system ui has stopped’. From that moment the phone is consuming battery charge in just three hours. I normally spend a day using the phone on calls & Internet but without the battery discharging that fast! The phone is also getting hot even when the mobile data is off. The message pop-up has not shown again but something isn’t working right! Please help me. Am so frustrated carrying a charger all the time. Thanks for your quick response

Solution: This error message is caused by system incompatibilities. It could be because of an app you have recently installed or if you are using a custom ROM it could be the ROM itself. There are various ways of solving this problem however the best and most direct way is to do a factory reset on your device. Backup all your important data first before doing this procedure.

  • Turn off device
  • Simultaneously press and hold the power button + volume up button + home key until the Samsung logo appears, then release only the power button. Release the volume up button and home key when the recovery screen appears.
  • From the Android system recovery screen, select wipe data/factory reset.
  • Note Utilize the volume up/down keys to highlight and the power button to select.
  • Select Yes — delete all user data.
  • Note Allow several seconds for the factory data reset to complete.
  • Select reboot system now.
  • Note Allow several minutes for the reboot process to complete.

Once the process has completed do not install any third party apps on your device yet. You may update the apps in your device. Observe it first and see if the error message appears. If it’s gone then an app may have caused it. Now one by one install your favorite apps at the same time observe if the issue comes back.
