S4 Does Not Turn On
Problem: Hi, I was browsing thedroidguy.com and was unable to find a solution to the problem I’m currently experiencing. My samsung S4 (GT 19500) has been off for a couple of weeks now, and I have no idea what happened. The phone won’t turn on at all unless it’s connected to the charger. Which then leads to a grey battery sign display which appears for a couple of seconds and then disappears for about 4 seconds and then reappears. This loop goes on as long as the phone is connected to the charger. I tried the volume up, home and power button combo which displays the intro Samsung S4 message, this message is shown also in about 4 second intervals but only as long as I’m holding on to the three buttons. When i let go, it goes back to the grey battery display. The volume down, home and power button shows the message from the first image in the link below (the warning OS message)
When i click volume up, it goes back to the grey battery.
Solution: It looks like the phone may have a hardware issue.You should however do some troubleshooting first to eliminate other causes.
The first thing you need to do is to do a battery pull. Take out the phone battery then press and hold the power button for a minute. Reinsert the battery then turn on your phone. This procedure clears out any residual power in the phone and also clears out the phone RAM.
If the problem still persists then try to replace the battery with a new one. In some cases a faulty battery can cause this type of issue so we should eliminate this possibility.
Try connecting your phone using a USB cord to a computer running on kies. If your phone can be detected then backup its data. Once you have backed up your data attempt to do an emergency firmware update.
Go to Tools and choose Firmware Upgrade and Initialization.
Enter the name of your phone.
Input the model name of your Galaxy S4 (in CAPS). It is found at the back of its casing.
Kies will now verify if your device is supported along with a warning message saying that all data from your device will be deleted during the process.
Click OK if you agree with it.
Kies will download and initialize the firmware update. Wait until it finishes.
Just hit Continue with every warning message until you reach the emergency recovery process.
Don’t forget to put a check on the confirmation message saying, “I have read all of the above information” once you have performed all the required information in the window.
Configure your desired information saving option, connect to Kies and switch your phone to Recovery Mode.
Hit the Start Upgrade button and wait until the process finishes. Do not interrupt the process.
After you see a confirmation message saying that everything is complete, hit the OK button to finish.
If the problem still persists then bring your phone to an authorized service center as this may already be a hardware related problem.
S4 Turns Off When Back Part Is Tapped
Problem: Hello, My Galaxy S4 turns off when the back of my phone is tapped. If it is in my pocket it happens alot. Sometimes it restarts but most of the time it just shuts off. Even a slight tap does it such as laying the phone down. Is there any cure for this other than getting a new phone? Thanks!
Solution: This issue is most likely caused by a loose component or connection inside your phone. What you can do on your end is to first check the battery and see if it is properly secured in its place. If it has room to move around then this may be the cause of the problem. Check the battery contact points of your phone and make sure that it does not move. If possible, try to replace your battery with a new one.
If the issue persists then you should bring your phone to an authorized service center. Have them open your phone and check for any loose connections.
S4 Retrieving Data From Bricked Phone
Problem: Hi, I have an S4 M919 and it has been bricked for almost three months now. It got bricked overnight and I’m just trying to find the most affective way possible without losing my data. So I researched about it and finding ways to fix this but some would lead me to think that it was soft bricked and others would lead me to think it’s hard bricked. (I take out the battery, put it back in while I press the power, home and bottom volume key. My phone would vibrate, it says that if I want to continue press the top volume key, which I do. It then shows the android shows up for a split second and it shuts back off). Alright, after about a week of my phone being bricked it turned on and I tried to back up my pictures from my gallery but as soon as I got to the ones I was trying to save, I ran out of space. The following day, it got bricked again.. Is there a way to unbrick my phone, and backup my pictures ASAP without downloading? I hope you can find a solution for this. Thank you
Solution: You should first try to use a new battery on your phone. Make sure to connect the phone to the wall charger for at least 20 minutes before turning it on when you insert the new battery.
If the issue persists then try connecting your phone using a USB cord to a computer running on Kies. Turn on your phone and if it is detected by Kies then you can backup your phone data.
S4 Stuck In Boot Loop
Problem: Hi. I was wondering if you are able to assist me, i have a Samsung S4 GT-I9500. it is currently stuck in bootloop, i am unable to enter recovery mode as it does not process the command. is there ANY way i can restore my phone without losing my data? Thank you very much in advance.
Solution: What you need to do first is to try to boot your phone in Safe Mode and check if it proceeds.
Turn the device off completely.
Press and hold the Power button.
Once the Samsung Galaxy S4 logo appears on the screen, release the Power button.
As soon as you release the Power button, press and hold the Volume Down key.
Continue holding the Volume Down key until the phone has completed the reboot process.
If you can read ‘Safe Mode‘ at the bottom left corner of the screen, release the Volume Down key. Otherwise, repeat the process until you can boot the phone to Safe Mode.
If your phone is able to boot then the issue may be caused by a third party app installed in your phone. You will need to figure out what app is causing this and uninstall it. Try starting with the latest app you installed prior to this issue occurring.
If your phone does not boot in Safe mode then proceed with wiping the cache partition of your phone.
Turn off the device.
Take out the microSD card (if you have one installed).
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.
After the the cache wipe is complete, press the Power key to select reboot system now.
Press the Power key to select. The phone will automatically restart after the cache is wiped.
