Problem #1: Galaxy S5 unable to connect to mobile data

Hi guys. Odd problem here. I recently encrypted my Samsung Galaxy S5, and am now unable to connect to mobile data (4G, 3G, EDGE, anything). A few detailed points: This only started happening after encrypting my device. I did upgrade to Android Marshmallow 6.0.1 a few days prior, but my mobile data was working normally after the upgrade. I doubt the problem has to do with reception as I am in the same areas it has always worked in, and it’s not that I don’t have bars when I AM connected, but that it won’t connect at all.

I have cleared the cache partition as per the articles I have found on your site, with no change. I am sometimes able to connect briefly by going into airplane mode and then coming back out, at which point it connects and works normally for a few minutes before disconnecting again, but this does not always work.

I checked the LTE connection, but I don’t have the LTE/WCDMA/GSM connections you talk about. Instead I have it set to automatically roam across 4G/3G/2G. I’m assuming this is because I am in Australia working off different wireless standards.

I have taken the SIM card out to test signal connection with no issues. I have booted into safe mode and the issue is still occurring. Simply turning off and on the mobile data will sometimes work, but not always.

GPS works as the offline Google Maps I have downloaded will still accurately track my position without the mobile data. Connected Wi-fi is similarly unaffected. When I go into ‘About device’ and select ‘Status’, while it does give me my correct carrier and a signal strength (~1-5dBm 35asu) and the service state is ‘In Service’, the ‘Mobile network status’ is ‘Not connected’ (despite being on in my phone settings) and the ‘Network type’ is ‘Unknown’. But then it also says ‘My phone number’ is ‘Unknown’, but I am able to make/receive calls just fine. I have also restarted many, many times whist troubleshooting. Phone details are as follows:

Model number: SM-G9001

Android version: 6.0.1

Android security patch: level 1 July 2016

Baseband version: G900IDVU1CPC1.

Thank you guys so much for your assistance. I’ve tried solving this myself but can’t get it working. Anything you could do would be greatly appreciated. — Christopher

Solution: Hi Christopher. If you’ve been following some of our articles that answers mobile connection issues, you’ll should notice that you are yet to do two important things. One is to do a factory reset and the other is to contact your wireless carrier.

Factory reset is the next logical step after doing all other software troubleshooting steps. The problem may be caused by an operating system glitch so it’s important that you reset everything back to factory default first. To do a factory reset on your S5, kindly do these steps:

  • Power down the Galaxy S5.
  • Press and hold the Volume up button, the Home button, and the Power button together until you see the Android on screen.
  • Use Volume down to highlight the wipe data/factory reset option and press the Power button to select it.
  • Use Volume down again to highlight Yes – delete all user data and press Power to select it.
  • Use the Power button to select Reboot system now.
  • When the S5 restarts it should be completely wiped and ready to set up again.

Factory reset will wipe everything that’s stored in your phone’s primary storage device (SD card will not be affected) so it’s important that you create a backup of important personal data before proceeding. In the event that your phone continues to behave abnormally and the issue remains, do not hesitate to let your wireless carrier know about it. There may be some account- or network-related issues causing it that only they can fix.

Problem #2: Galaxy S5 won’t charge

Hi. So my phone suddenly stopped charging the night before last. I put it on the charger before bed and everything was fine as usual. The little lightning bolt appeared and there wasn’t any issue with the phone.

Then yesterday morning, I noticed my phone was at 6% battery life, which means that probably sometime shortly after I put it on the charger, something happened and it stopped charging.

I thought maybe it was the charging cord, so I tried using my car charger, which did not work.

Then I tried my computer USB and I tried my portable charger, none of which worked.

What keeps happening is that I’ll plug the charger in, and the battery sign with the lightning bolt will appear, only to disappear seconds later. Usually the battery with the bolt stays up and it fills with the green light to show you it’s charging, but it just comes up empty and then disappears…and then returns again empty and disappears. This is when the phone is off.

When it’s turned on it doesn’t show the lightning bolt or register a charge at all. I thought perhaps it was a battery issue, though the phone is barely over a year old, so I bought a new battery, which made it so I could turn my phone on, but it still won’t take a charge.

The people at T-Mobile said they don’t see anything wrong with my port at all. They tried several chargers there and couldn’t get it to charge either. They had no idea why it wouldn’t charge.

I tried cleaning the port with a dry toothbrush and air, I tried jiggling the charger in the port, I tried doing a soft re-start where you hold the power button down for a minute while the battery is out of the phone, and I tried starting the phone in safe mode to make sure that power sharing app wasn’t somehow the problem. I’ve done everything but a full factory reset on my phone. Do you have any other suggestions besides the factory reset or buying a wireless/battery wall charger?

I really can’t afford a new phone, and I don’t understand how a phone can just stop accepting a charge literally overnight for no apparent reason at all. — Heather

Solution: Hi Heather. Doing a visual check on the charging port cannot know the true status of said equipment. It may look good on the outside but it may actually be suffering from corrosion or some contacts may have come loose inside. The only way to know if it’s working is by having the phone checked in a repair center. Before you do that though, we highly recommend that you do a factory reset first. This is the only procedure that you can do on your end. Its aim is to check if the root of the problem is only at firmware level. If the true cause is hardware in nature, which means nothing will change after a factory reset, that’s where repair or replacement comes in.

Problem #3: Galaxy S5 won’t turn on after an update

Hi Droidguy.

Device: Samsung Galaxy S5 Prime (SM-G906K). After updating my S5’s software to the latest Lollipop version, the phone wouldn’t boot after restarting. I have tried taking the battery off for 10+ minutes and pressed the power button for a minute while the battery was taken out. I have also attempted going to recovery mode but it wouldn’t even let me go to it in the first place!

Sometimes I get blue light on the top left corner and I get notifications but obviously can’t see anything on the screen. After hours and hours of work I have finally got it to download mode and installed stock ROM for Marshmallow and it finally worked. But after a day while I was listening to music on the phone it just died on me, while the battery wasn’t even low. Strangely, it started working again after a day! This repeated for about 3 times where if i try to restart my phone or when it randomly dies on me it wouldn’t boot for over a day.

Now I have already purchased a new phone (Note 7) but it won’t be available for me to use for a week, so could you please provide a solution or a quick fix to transfer all my data inside my phone as it died again last night. — MC

Solution: Hi MC. Well, there’s obviously nothing that you can do if your phone refuses to boot up normally during select days. You can only move your files when it’s up and running.

As far as solution is concerned for this problem, the only suggestion that we can give is repair or replacement. We have no way of knowing what the problem is. The issue may be isolated to the screen assembly, or to another unknown component.

Hopefully the device will work again in the coming days. Once it boots back up, try to boot it immediately to safe mode and connect it to a computer so you can transfer your files. To restart in safe mode, follow these steps:

  • 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.

We’ve encountered a few cases in the past wherein the cause of a similar issue is a bad Power button. Make sure to press the Power button hard when trying to use it.

Problem #4: Galaxy S5 backup app not working

I have AT&T Pro Tech. I’m told to use Wi-Fi to back-up data. Since I have no access to Wi-Fi at home, I go to the local library and use their free Wi-Fi which works fine for all my other Wi-Fi needs. It starts out working okay with the backup but then quits. For the last 6 weeks, it’s showed I have 1.2GB (of 50 available) backed up, no matter how long I’m there. It says it’s backing up data and then quits; twice has said all contacts are backed up but then will say I need to back up contacts.

I never willingly added this app to my phone; it just appeared one day. If it won’t work, then how do I get rid of it. Know you’ll have more questions so email me. I need help. Maybe I’m missing something here. I have done all of your suggested fixes already but don’t think that’s the problem. Thanks. — Barbara

Solution: Hi Barbara. You should have mentioned the name of the app you’re having trouble in your problem description to help us identify the issue. Since we can’t use the information (or lack thereof) you provided, we suggest that you do a little research about it and see if you can contact its developer. If the app happens to come from your carrier, call them and let them help you figure the issue out.

Problem #5: Galaxy S5 apps won’t load with mobile data after Marshmallow update

Hi. Since updating my Samsung Galaxy S5 to Android 6.0.1 Marshmallow, certain apps on my phone won’t load or run properly when just using mobile data. I have no problems with the apps when using Wi-Fi.

I have tried the following and also contacted my provider (Optus) who have insisted i should do a factory reset Marshmallow data problems If you suffer from data connectivity issues after an update, the solutions are equally low-brow: turn your phone off and on again, toggle mobile data on and off, remove and replace your SIM card and toggle Airplane Mode on and off. If these don’t help, hit your carrier support pages to see if others are having the same problem and contact your carrier to see if there are any known connectivity issues on the new Android version. — Jessica

Solution: Hi Jessica. First of all, make sure that the affected apps properly updated to make them compatible with the new operating system version. They may have worked great with Lollipop or the previous iteration of Marshmallow but that may not be the case with the most recent update you have installed. Keep in mind that updating the operating system does not automatically update apps as well. Some app developers are keen to release updates to their own products once new Android updates are released but there are also some that may take a long time to do so. Others may no longer care to make their products compatible at all! If there’s no update available for the said apps, consider contacting their developers for direct assistance.

If the apps in question are already updated, the next thing that you want to do is wipe the cache partition. 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 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 wiping the cache partition won’t help, the final but drastic solution is factory reset. Refer to the steps above.
