Problem #1: Galaxy S5 stopped charging normally after an update, only charges when connected to PC

Since the last update my phone will not charge with a wall charger or car charger. It will only charge on a USB on a computer. Tech support confirmed that this issue was legit and that there were also problems with others as well but it was with them connecting to a PC to exchange info, not a wall charging issue. It also is having massive power drains now.

I took the phone to a very reputable battery/cell phone shop and had them check the battery and port and they tested fine. I contacted Samsung and they sent me to Best Buy for a firmware flash. But they couldn’t even flash it cause they said their software could only communicate with my phone so far and would stop.

So you know before the update, I had no issues with this phone. But within 30 minutes of the update, I noticed my phone would start to charge when I plugged it in and then loop like I plugged it in again over and over as I watched the battery still slowly drain.

Other chargers aren’t even acknowledged by my phone any more. But a USB port on any PC seems to charge it! Any thoughts?

I was trapped in to buying a new phone cause I’m on the road a lot and it has to charge on a car charger. So whatever I try at this point won’t matter. Thanks. — Ed

Solution: Hi Ed. There are three important steps that you can do on your end after an update, especially if you encounter problems afterwards. These steps are:

  1. refreshing the cache partition
  2. updating ALL apps
  3. wiping the phone with master reset

The first one is necessary after an app or system update installation. Sometimes, the system update can get corrupted after an app or firmware update installation so you want to ensure that the device is using a new cache. A corrupted cache can make apps behave erratically and in order to fix the issue, you must simply refresh it. Here’s how it’s done on a Galaxy S5:

  • 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.

The next thing you want to do is to make sure that all your apps are up-to-date. This step is often overlooked by many Android users. Updating the operating system does not mean apps are automatically updated as well. Although most users go through with their lives normally after a system update, some may not be so lucky, particularly if one of the apps now become incompatible with the newly updated operating system. In some cases, problems show right away after an update because an app may be no longer be compatible with the firmware. This is often true for apps that were originally not designed to work with more advanced Android version. In this context, you have two things to do:

  1. check that EVERY app you install is compatible with the Android OS,
  2. install the latest update after you’ve verified that every app is compatible

Simply visit the Google Play Store page of each app to see if it’s designed to work with whatever OS version running on your phone. We are assuming of course that you only install apps from Google Play Store. If you have apps from third party sources (outside of the Play Store), it’s your responsibility to make sure that said apps are compatible with the OS.

Finally, the ultimate step that you can do on your end (there’s only so much that you can do, right?) if master reset. As the name suggest, master reset, also known as factory reset, will restore the software environment of your phone to its last known, working state. This means that bugs and glitches that may have developed after some time will all be eliminated from the system. With the OS now reverted to its known working state, there should be no reason for your issues to occur. However, if the problem remains after performing a factory reset (without any apps installed yet), that can mean only two things — either there’s a problem with the firmware in the first place, or there’s an unknown hardware malfunction behind the trouble.

In order to fix a firmware issue, you can try to flash the previous OS version (this may not be possible if your computer won’t even recognize the phone). The important thing to remember is, if the issue continues after a factory reset and you haven’t installed anything yet, you should consider having the phone repaired or replaced.

Problem #2: Galaxy S5 has missing serial number | Galaxy S5 won’t connect to other networks

Hopefully you guys can help cause I have been having several problems. I bought a Samsung Galaxy S5 phone from an individual who stated the phone was an unlocked CDMA/GSM phone that he had purchased to use on NTELOS network and no longer needed it. The thing is the phone didn’t have a serial number. It is not found on the box, behind the battery, or even using the Android app. It only indicated all 0’s for the serial number. I contacted Samsung who told me to contact US Cellular to find the serial number; everyone was no help.

My plan was to use the phone for Straight Talk since that was what I had. So they sent me an AT&T SIM card to use for my area. After several tries, the phone would never connect to AT&T from anywhere. So Straight Talk assumed it was bad and sent me another one. Prior to receiving the last SIM card I decided to try my Verizon SIM card that was I was using in a previous phone in the S5 and it would call out no problem, just didn’t have data. After trying the last SIM card from AT&T it would still not work. I looked in the more network settings and it only has settings for CDMA/LTE and CDMA only, no GSM and etc., so I think the fella lied to me about it being a GSM phone. Plus there is no option to get into the APN settings. It is not even listed under mobile networks. I am curious would this phone work with the Straight Talk cdma/LTE sim card, but if I can’t change the apn settings it seems like it would be incompatible? Thanks. — Nick

Solution: Hi Nick. The absence of the phone serial number is an interesting fact in this case. If you can’t find it using the Settings app, the system of your wireless carriers may also be having a hard time recognizing the phone. A serial number is in fact one of the critical information used by carriers to properly provision (register) a device in their networks. This may or may not be the main reason why the phone is unable to connect to any network at this time. We have no way of checking this ourselves but we are very positive that a missing serial number can potentially result to network issues. Your average technical support representative from your carrier may not be able to confirm this as well as provisioning is supposed to be automatic for GSM networks.

If your current phone is a CDMA device, it needs to be network unlocked first before you can use its SMS, MMS, voice calling and other features in other networks. Once it’s been network unlocked, the next CDMA carrier will need to reprogram it again before it will be allowed on their network. During the provisioning or registration process, a serial number is needed as one of the critical information to identify a device. If this phone is unable to identify itself because of its missing serial number, no provisioning can take place. For GSM phones, they need to be network unlocked too but registration to another network is almost automatic once you insert a SIM card to it. To check if your phone is a CDMA or GSM phone, look for the exact model number and use Google to identify its network specifications.

The previous owner may have modified the phone’s software and deleted the serial number in the process. The missing serial number should be enough reason for you not to take the phone in the first place.

Another possible reason why this S5 won’t connect to AT&T or other networks is the fact that CDMA phones, like those from Sprint and Verizon, would normally have limited functionality when used in other networks. There’s also a chance that your phone’s operating frequency bands are different from those of other networks in your area. This means that your phone is incompatible with said networks. Unfortunately, there’s nothing that you can do about it as this is a hardware limitation. Operating frequency bands depend on hardware network chip in the phone. Together with the missing serial number, any of these two possible scenarios can be the cause of the problem.

If still possible, consider returning the phone and get your money back. If you can’t do that, you can keep the phone as an expensive paperweight.

Problem #3: Galaxy S5 status bar is missing

Hi. I really can’t remember what I did that has caused this problem but I remember that I was trying to restore some settings I had prior to make a factory reset because my Samsung GS5 had been infected by a virus which redirected all my attempts to visit any web pages I tried to visit. After the factory reset, everything seemed to be working as usual but most (if not all) my setting had to be manually replaced. I was trying to turn on the setting which turn off the screen while you have your ear on the cellphone during a phone call. All of a sudden, I noticed that the Status bar on top of the page wasn’t there anymore; it had totally disappeared for an unknown reason.

I also discovered that many other features too long to list were also not available anymore. I tried countless attempts to solve these problems without success and I don’t know what else to do anymore. The last thing I wanted to try is to perform a Factory Reset one more time but there seems to be no way to switch the pone to the MTP USB mode. I can turn on USB debugging but I can’t find how or where to switch USB mode to MTP. Because of it Kies can’t detect my Samsung GS5 USB connection. My Windows 10 device manager is detecting it but it doesn’t appear in the disk drive listing anymore… I tried hard as hell to find solutions to recover the status bar but I found nothing at all about it on Internet.

I also tried to find diagnostic and troubleshooting tools for the Samsung GS5 but I found none. So, I’m pretty desperate. I hope that you’ll find a way to help me and I thanks you in advance. — Chris

Solution: Hi. There are many apps, particularly launchers, that can make the status bar disappear. There is no option under the default Android OS to hide the status bar however so this must only be caused by an app. It’s hard for us to tell because you didn’t give us any system and app information on your device. To see if a third party app is causing the issues, boot the phone to safe mode. Here’s how:

  • 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.

Safe mode blocks third party apps and services so if the status bar returns, that’s a confirmation that a setting in one of your third party apps is to blame. Uninstall apps until you’ve pinpointed the app you don’t want.

If nothing changes even when your phone is in safe mode, do a factory reset. Factory reset should also resolve the rest of your issues here.

As a friendly reminder, make sure to understand what you’re doing when changing phone settings next time.

Problem #4: Galaxy S5 won’t turn on after charging

Hello! After much browsing of your website and many tries of the tips and tricks you have posted, I am still unable to do anything with my Samsung Galaxy S5. Last night the battery was getting low, so I put it on to charge via the USB and plug in the wall method. This is always how I charge my phone. The phone would not recognise that it was charging once plugged in, so I tried a different charger. Still nothing. I have a second S5, so I tried switching the batteries (identical batteries for both phones – this one fully charged) and I still can not turn the phone on. I then connected it to my computer to see if that would charge it or even show up in the ‘this pc’ section.. but still nothing appears.

I have tried to do the factory reset (holding Volume Up, Power Button and Middle button at the bottom of the screen) and still absolutely nothing happens. No vibrate, nothing on screen. I have also tried removing the battery for a good few minutes and then reinserting it (the charged one) and still nothing happens! Tried using a different charger, tried charging from computer, tried switching to an already fully charged battery, tried factory reset, tried soft reset (removal of battery for 10 seconds). Is there something I am missing? I very much appreciate your help. If the phone is dead, then I guess it is dead, but I would very much like it not to be, lol. Thank you so much for reading and I look forward to your reply. — Dru

Solution: Hi Dru. The most straightforward thing that you can do in this case is by using another battery. If a phone remains unresponsive or won’t turn on at all with a known, working battery, that’s a clear sign that the phone’s dead. You can try booting the phone to other modes to see if it turns on but we doubt that it will. If you want to give booting to other modes a shot, below are the steps:

Boot to Maintenance mode:

  • Charge the phone for at least 30 minutes.
  • Turn off the phone.
  • With the phone turned off, press and hold the Power and Volume Down Buttons at the same time
  • Continue holding these Buttons until you see the special maintenance boot mode screen.
  • Release both the buttons.

Boot in Recovery mode:

  • Charge the phone for at least 30 minutes.
  • Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  • When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  • When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  • Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  • You can either wipe the cache partition or do a factory reset when in this mode.

Boot in Download Mode:

  • Charge the phone for at least 30 minutes.
  • Press and then hold the Home and Volume DOWN keys, then press and hold the Power key.
  • When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume DOWN keys.
  • Wait until the Download screen appears.
  • If you can boot the phone in download mode but not in other modes, that means that your only way out may be to flash a stock or custom firmware.
  • Use Google to look for a guide on how to do it.

Boot in safe mode:

  • Charge the phone for at least 30 minutes.
  • Press and hold the Power button.
  • Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
  • Continue holding the button until the phone finishes rebooting.
  • Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
  • The only difference of safe mode from normal mode is that the former prevents third party apps from running. If you can boot the phone in safe mode but not in normal mode, uninstall all apps until the issue (that prevents you from booting normally) is eliminated.

Problem #5: Water damaged Galaxy S5 no longer charging properly

Reprogramming, Software, Charging Port, or Virus ISSUES?!?!

Samsung Galaxy S5 Lollipop Version 5.0.1.

Carrier: Union Wireless

My phone was water damaged, heavily spilled on but not submerged. It was placed in a bag of rice for almost a week and would only rarely vibrate when plugging in or pushing power button, so it went in a drawer for a few months. I recently pulled it out after discovering I could reprogram it myself… I completed the programming via laptop connection, somewhat successfully. However, I am still experiencing MULTIPLE ISSUES W/CHARGING!!

Problems such as:

  • not holding a charge,
  • battery draining quickly & charging very slowly,
  • refusing to recognize charging cords/boxes,
  • only accepting a charge when plugged into my PC,
  • accepting only ONE charge cord/box combo after starting via laptop.

Now it will barely charge and mostly via PC connection. I have tried numerous things like:

  • Reprogramming again,
  • clearing cache both in safe mode and non,
  • battery replacement + clearing battery data (with battery removed & holding power button for 60 seconds), and
  • charger port cleaning… as far as I know.

I am thinking of downloading the Android SDK Platform Kit/Files but honestly do not know what I am doing when it comes to the software/coding areas. I simply have searched via Youtube and Google LOL. Any ideas or advice would be greatly appreciated!! If there is any other information needed, please let me know also where to find it. I look forward to hearing your response! Thank you. — Andrew

Solution: Hi Andrew. There’s one critical thing that you missed considering that the phone was exposed to water before and that is a thorough hardware check. Water damage can result to all sorts of problems so you want to make sure that bad hardware is not to blame. Make sure that you let a professional open and examine important hardware components like the charging port, battery, and generally, the motherboard. If corrosion has already set in at this time, it may now be impractical to repair the device. Nevertheless, if you really want to get to the bottom of the issue, a full hardware diagnostics is necessary.
