How To Fix T-Mobile Samsung Galaxy S4 Problems and Errors

While we’ve already published more than 20 parts of our Samsung Galaxy S4 Problems series, we would like to provide support to our readers who cannot get support from their respective carriers or service providers. Hundreds of our readers from the U.S. are subscribers of the four biggest wireless companies, however, they prefer to contact us to ask questions. We’re cool with that. In fact, we’re open to everybody regardless of the brand of the phone or service provider.

For those who have problems with their phones, feel free to email us at It’s a free service but we urge you to please provide as much details as possible so that we will know where to start and how to fix your problem. We also have Facebook and Google+ pages you can use to communicate with us.

Problem: Hi guys, I really need your help now. My phone, which is a Galaxy S4 I got from T-Mobile, cannot continue to the home screen. It will power on but stays in the Samsung logo. I am only an average user and I don’t know how to deal with this problem. I purchased this phone thinking I can use it without having problem but it seems I was wrong. I don’t know what information to include here but as far as I know, I didn’t do anything that may have triggered this problem; it just happened out of the blue one morning and that’s it. I would do anything you would suggest but please be very specific so that I won’t mess my phone even more. — Clarence

Solution: Since we don’t know for sure what caused the problem, let’s take the safer way to troubleshoot this. That said, we have to assume what happened. Based on my experiences, problems like this is often caused by a rogue app and a firmware glitch. I wouldn’t want to drift further from those possibilities for now.

If this problem was caused by a third-party app, you can force the phone to boot up in Safe Mode and from there, find the app that’s causing the problem and uninstall it, then you can boot up to normal mode. Here’s how you boot your phone to Safe Mode…

  1. Turn the device off.
  2. Press and hold the Power key.
  3. When ‘Samsung Galaxy S4’ appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. Safe mode will display in the bottom left corner of the screen.
  7. Release the Volume down key when you see Safe Mode.

Again, if your phone successfully booted up to safe mode, it means one of your apps is causing the problem. Find that app and uninstall it. Perhaps the one you installed before this problem happened…

However, if the phone refuses to boot up even in safe mode, I suggest you try booting it to recovery and wipe its cache partition. Don’t worry, wiping the cache partition won’t delete any of your files. To wipe the cache partition, follow these steps:

  1. Turn off the device.
  2. Press and hold the following three buttons at the same time: Volume Up key, Home key and Power key.
  3. When the phone vibrates, let go of the Power key but continue to press and hold the Volume Up key and the Home key.
  4. When the Android System Recovery screen appears, release the Volume Up and Home keys.
  5. Press the Volume Down key to highlight ‘wipe cache partition.’
  6. Press the Power key to select.
  7. After the the cache wipe is complete, press the Power key to select reboot system now.
  8. Press the Power key to select. The phone will automatically restart after the cache is wiped.

After this and phone still won’t boot up successfully, then there’s no other option but to proceed with factory reset. You can still do this via the recovery mode.

Get Google Voice icon back on keyboard

Problem: Hi guys, I am Janice and I’m emailing you in behalf of my father. Also, the reason why I emailed you is because I am not technical enough to know how to bring back features that were lost in the phone. My father is a war veteran with both hands almost cut off. In other words, it’s difficult for him to type text messages. Instead he used to dictate what he wants to send to his phone and he was pretty good at it until that feature is gone. He has the Samsung Galaxy S3 phone and he’s on T-Mobile network. All he wanted to know is how to bring back that feature so he could just speak to the phone what he wants to send. He said, there was a microphone icon on the keyboard before but now it’s gone. Please help.

Solution: Hi Janice, thanks for providing all necessary information about your concern. Don’t worry, it’s easy to bring back the Google Voice button on the keyboard. Just follow these steps…

  1. From the Home screen, tap the Menu key.
  2. Choose Settings.
  3. Tap on My device tab.
  4. Scroll down a bit to Language and input and tap on it.
  5. Look for Google voice typing. There’s a checkbox beside it, make that is checked.
  6. The Microphone icon (Google Voice) should now be displayed on the keyboard.

I hope this helps. Thanks.

“Unfortunately, the process has stopped”

Problem: Droid guy, thanks for this great service you provide. I’ve been an avid follower of your website and Drippler. I have a problem that started lately. At least, 3 or 4 times a day, I would get the error message, “Unfortunately, the process has stopped” and I don’t understand a bit what it means or what app it’s referring to. By the way, my phone is a 2-year old Galaxy S3 which I got from T-Mobile. I’m still using their service but I don’t think my service has something to do with it. I know you guys have encountered this problem before so if you know how to fix this, please let me know. It’s not actually impacting my use of the phone (yet) but I’m afraid it will become worse soon and it’s very annoying.

Solution: I understand the feeling of frustration when your phone starts to malfunction or gives you error messages every now and then. But I can assure you this problem isn’t serious, although it concerns one of the Google apps you have in your phone. In case you noticed which app was running when this error message popped up, you can solve the problem by simply clearing the cache and data of that app to bring it back to its default settings. However, if you don’t know which app, then there’s a general way to fix this problem. Here’s how…

  1. Pull the Notification Bar down.
  2. Tap on the Settings icon (cogwheel) on the upper right corner.
  3. Touch the More tab.
  4. Tap on the Application Manager.
  5. Swipe left twice to display contents of the All tab.
  6. Tap the Menu key.
  7. Touch Reset app preferences.
  8. Tap Reset apps.

The last time I encountered this problem was last week. It was my customer’s phone and the procedure above solve the problem. I hope this fixes your problem too.

Phone turns off while booting after update

Problem: Droid guy, I just updated my Galaxy S4 to the recent firmware and it seems like I got a bad update because my phone won’t continue booting up. I can get it to reach the Samsung logo but after that, it turns off and I have to hit the power button again. I was able to boot it up to Safe Mode, though, but I was also getting errors from there. I’m at a loss here dude, so I really need your help. The phone was working perfectly prior to the update. If I had known this would happen, I shouldn’t have updated it. Thanks for you time and effort. — Marlon

Solution: Since the phone can boot up to Safe Mode, it is obvious the problem is with the firmware and it is more likely that some data may have been corrupted during the installation of the new firmware. I’m sure the phone can boot to recovery as well, so from there, we will perform factory reset. However, before that, boot the phone to Safe Mode again and backup all your data or those that you can’t afford to lose. After that, follow these steps…

  1. Turn off the device.
  2. Press and hold the following three buttons at the same time: Volume Up key, Home key and Power key.
  3. When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
  4. When the Android System Recovery screen appears, release the Volume Up and Home keys.
  5. Press the Volume down key several times to highlight ‘wipe data / factory reset.’
  6. Press Power button to select.
  7. Press the Volume down key until ‘delete all user data’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, ‘Reboot system now’ is highlighted.
  10. Press the Power key to restart the device.

I hope your problem will be fixed by this.

“Unfortunately, Contacts has stopped”

Problem: I have a problem with my phone that whenever I make a call, an error message pops up telling me that my Contacts stopped working. I think it was the recent update that caused this problem but I’m not really sure. I have a limited knowledge when it comes to smartphones that’s why I need your help on how to fix this problem. I can receive calls from anybody but I can’t make calls due to the error message. If you can explain to me why this happens and provide me a fix, I would surely appreciate that. Continue what you guys are doing, you can help millions of people with it.

Solution: You may be right, the recent update may have messed up your phone a bit affecting the dialer and the Contacts app. But don’t worry, this problem is minor and can be fixed by simply clearing cache and data of apps concerned. Since the error message says it’s the Contacts app that crashes, that’s the first app we’ll have to look into.

  1. From any Home screen, tap the Menu key.
  2. Tap Settings.
  3. Tap the More tab.
  4. Tap Application manager.
  5. If necessary, swipe left or right to display the All screen.
  6. Tap Contacts. (DO NOT clear the cache and data of Contacts Storage)
  7. Tap Clear data and then tap OK.
  8. Tap Clear cache.

It would be wise to reboot the phone after this just to refresh the memory. If the problem, however, persists after the procedure, then do the same thing to the dialer app. I hope that solves it.

  1. So my Galaxy S4 is stuck on the T-Mobile 4G LTE white screen. I rebooted and did whatever I could to turn it back on properly but its just stuck there. What do I do?

  2. My s4 microphone works properly expect when I get a phone call. People cannot hear what I am saying and I cannot hear what they say too. Expect that I can hear music I also can record voices. It also does not work by headphone
