Problem #1: White triangle icon near Galaxy S5 4G indicator

Hello. I have multiple issues. I recently bought this refurbished phone on eBay, so I hope that my issues don’t stem from a faulty sale, but that is a possibility. I previously had a Galaxy S4.

1) My Google account has been established on the S5, but all of the apps that I have downloaded on my old phone have not transferred over to the S5. In the past, simply logging into my google account on a new phone has moved over all of my apps. “Sync app data” is selected when I look at the Google account sync details. I also had moved as many apps as possible from device storage to SD card storage on my S4, and installed that same SD card on my new S5. My pictures and documents HAVE transferred to the new phone, but that could be because I did a Verizon Cloud transfer of this data.

2) Above the service bars, there is a small white triangle. This is next to the 4G icon. I have turned off roaming capabilities, so I shouldn’t be roaming.

3) I can’t send picture message through the texting app, but I can send normal text messages.

Thanks for your help! — Sarah

Solution: Hi Sarah. Let’s answer your questions individually.

1). We know what you mean. Apps are usually installed to a new device once you log-in previously used Google account from another phone. If that doesn’t happen on your S5 right now, we recommend that you install your apps via Google Play Store. Simply open the Play Store app, go to the menu and tap “My apps & games”.

2.) There is no white triangle in the list of the standard Galaxy S5 icons so that must be coming from your carrier or a third party app. Try to contact the technical support team of your wireless carrier to gather more information about the said icon.

3.) The first thing you want to do in this case is to ensure that there is no on-going network problem in your area. This can be done by calling your wireless carrier. If they’ll say that everything is working fine, restart the phone and try to send an MMS to yourself. If it continues to fail, delete the cache and data of the messaging app you’re using. You can follow these steps:

  • Go to Settings.
  • Proceed to Applications.
  • Select Manage Applications.
  • Tap the All tab.
  • Look for the messaging app and tap it.
  • From there, you will see the Clear Cache and Clear Data buttons.

If the issues remains, review the APN configuration together with your wireless carrier technical team. The device is most likely not setup properly to send MMS.

Problem #2: Galaxy S5 not connecting automatically to mobile data

Hello. I have a Metro PCS Samsung Galaxy S5 with unlimited data but lately I’ve been having issues with my Samsung Galaxy S5 mobile data randomly turning off. I guess it happens when I’m in an area with limited service but the 4G network and bars used to turn back on (show up at the top of the screen) when I had service again. Now I have to manually turn on the mobile data in the settings section.

I tried taking the phone back to the carrier and explaining the problem but the guy there didn’t really know how to help and only suggested I close out open app windows and to turn Wi-Fi off when not in use. It’s incredibly frustrating to have to keep turning the data on just to send, receive, and use my apps. Please help! Thank you. — Nailah

Solution: Hi Nailah. An issue like this is sometimes caused by an operating system bug, or even a corrupted cache. The first thing that you can do is to clear the cache partition by doing these steps:

  • Turn off the device.
  • Press and hold the following three buttons at the same time: Volume Up key, Home key, and 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 cache partition.’
  • Press the Power key to select.
  • When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
  • Press the Power key to restart the device.

If deleting the cache partition won’t help, make sure to do a factory reset. Here’s how:

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

Problem #3: How to unlock APN settings of Verizon Galaxy S5

I recently bought a used Galaxy S5 that had been a Verizon phone but was already set up as Straight Talk and I just needed to activate it. After I activated it, it worked completely normally until I accidentally clear the APN. I have tried literally everything to reset it and nothing will work. It won’t let me add a new APN or reset to default (which is what I’d really like to do) when I open the one that is there it is called Verizon Internet but all the other settings are clear with the APN being the only one I can change. I know very little about fixing any kind of electronics and am completely lost! If any of this didn’t make sense i can try to explain it better. Please help if you can thanks! — Hannah

Solution: Hi Hannah. Verizon issued phones are designed to lock the APN settings and it usually takes some effort to unlock them again. An important requirement in unlocking a Verizon S5 is to have root access. Once the phone is rooted, you have to install another app to allow you to edit some system values.

We’ve come across a helpful walkthrough on what you need to do from XDA-Developers forum. Try to see if the suggested steps are still working. We haven’t tested the procedure ourselves but we do know that most tutorials from this site are reliable.

If you can’t figure out what to do, or if you find the steps beyond your Android knowledge, try to ask assistance from someone to ensure that you’re doing the steps right.

Keep in mind that rooting modifies your phone software and can lead to problems if not done correctly.

Problem #4: Galaxy S5 won’t connect to home Wi-Fi

My Internet cable connects through a modem to a very good router that connects by Cat5 cable to a new Netgear router acting as an Access Point inside my residence. That works great for various notebooks and DVD Players that access the WWW by WI-FI inside the house. It worked fine on my Nokia cell phone and my wife’s cell phone. Every device uses the same settings and same password. Instantly works. 

But when my brother was here over the Christmas holiday, his Galaxy S6 would NOT login to the Access Point signal. I just changed to a Galaxy S5 and am experiencing the same problem. My Galaxy S5 phone sees the Access Point signal very strong, but like my brother’s S6 it will NOT login.  I have checked all the settings a dozen times. He and I are inputting the correct password. When we try, our phones briefly flash “incorrect password.” So obviously the fault is the two Galaxy phones. What are we doing wrong? — Larry

Solution: Hi Larry. We have no idea what happened to your local network but the most likely culprit may be the Netgear router itself or its settings. Try to factory reset the router to bring it back to its default configuration. You can either refer to your router’s manual or to this Netgear knowledgebase page. If the netgear router was provided by your internet service provider, make sure to call them first to let them know about the problem. Doing a factory reset will erase all critical information that you might need to reconfigure it including the ISP name, ISP password, wireless security key, IP addresses, etc.

Problem #5: Galaxy S5 no longer connects to Wi-Fi

I cannot connect to any reliable Wi-Fi (that works with other devices and use to work with mine very well). This is real unusual and the Verizon store cannot figure it out. They called Verizon and tech support suggested a factory reset. It seemed to work for a few hours that night, and not since then though.

When you depress the WIFI selection the button marked “OFF” is grayed out and cannot be slid into the “ON” position.

I am using up data like crazy.

I have taken a battery out.

Powered off for an hour or so.

I have not wiped it all clean nor have I had it reimaged (as the Verizon store called it), but was thinking about it.

It is just a year old.

I have tried many things on blogs and other support sights like, Smart Network Switch ON and OFF. Interesting that the SMART Network switch is ON on a Factory settings reset. and Also the reset called for Always scan to be OFF.

I try it both ways, but I suspect WIFI is not reliable from possibly a hardware reason (maybe).

Any ideas or advice? — John

Solution: Hi John. Did you make any software changes prior to noticing the problem by updating the operating system, or installing some new apps? If you did, try to see if booting in safe mode will help. While in safe mode, all third party apps will be prevented from running so if one of them is to blame, the issue will not occur. Here are the steps on how to boot in safe mode:

  • Turn the device off.
  • Press and hold the Power key.
  • When ‘Samsung Galaxy S5′ appears on the screen, release the Power key.
  • Immediately after releasing the Power key, press and hold the Volume down key.
  • Continue to hold the Volume down key until the device finishes restarting.
  • Safe mode will display in the bottom left corner of the screen.
  • Release the Volume down key when you see Safe Mode.

If nothing changes even when on safe mode, there may be a hardware issue behind the trouble. Consider having the phone checked or replaced by Samsung or by your carrier.
