Samsung Galaxy S4 Does Not Boot

Problem: I have Samsung Galaxy S4, I have been using this mobile since two years, all of a sudden its not working, when I reinsert the battery, it displays the model of the mobile and doesn’t start further. Please help with my issue.  

Solution: If the phone does not go past the boot logo then there’s a possibility that this could be a software related issue. To troubleshoot this problem you need to take out the battery and the microSD card first. Press and hold the power button for at least a minute then reinsert just the battery. This will discharge the phone circuit then clear out its RAM. Try to turn on your phone and check if the issue disappears.

If the problem persists then you need to turn on your phone from the recovery mode. From here proceed with wiping the cache partition of your phone. This will delete the temporary data stored in the device which could cause the problem.

One last troubleshooting step that you should consider should the above troubleshooting steps fail is a factory reset from the recovery mode. Take note that your phone data will be deleted in this process so make sure to have a backup of your data before proceeding.

Samsung Galaxy S4 Buzzes When Switched On

Samsung Galaxy S4 Buzzes When Switched On

Problem: My fiance tried to power on his phone but it buzzed once and then this yellow screen with a static look to it popped up and then when black. This was after the yellow screen had just stayed there until the phone was powered off. He dropped his phone into the sink but the phone wasn’t even close to being submerged because it was empty. We don’t think its the battery because we tried mine and it did the same thing.

Solution: If this issue occured right after the phone was dropped in the sink then the issue is most likely caused by water damage. Try to dry the phone first by placing it in a bag of rice for at least 48 hours with the battery removed. After 48 hours reinsert the battery then turn on the phone. If it doesn’t turn on then connect it to its wall charger and let it charge for 20 minutes then turn on the phone again.

If the issue persists then I suggest you bring the phone to an authorized service center and have it checked.

Samsung Galaxy S4 Does Not Switch On Or Charge

Samsung Galaxy S4 Does Not Switch On Or Charge

Problem: Hi, My samsung galaxy s4 does not switch on nor does it show that the device is charging. I’ve used several new batteries and new chargers the phone refuses to do anything. While on charge the processor does heat up and so does the battery

Solution: This issue could already be hardware related. You can however do some additional troubleshooting steps such as cleaning the phone charger port using a can of compressed air or cotton bud dipped in alcohol. Once this is done charge the phone for at least 20 minutes then try to turn it on.

You should also try to discharge your device. To do this just take out the battery and the microSD card. Press and hold the power button for at least a minute then reinsert just the battery. Check if you are able to turn on the phone.If the problem persists then I suggest you bring your phone to an authorized service center and have it checked.

Samsung Galaxy S4 Switches Off Does Not Restart Issue

S4 Switches Off Does Not Restart

Problem: My phone was working perfect this morning then suddenly switched off and would not restart.  I took the battery out the back and put it back in and it came up with Android initialising then when blank again.  It has not powered up still 3 hours later.  I have took the battery out again and still nothing however when I press the button on the side to switch it on it buzzes but nothing happens.  Can you please advice me?  Many thanks.

Solution: There are a couple of factors that we should check for this type of issue. The first thing to do is to check if the issue is caused by a weak battery. Try connecting the phone to a wall charger and let it charge for at least 20 minutes. With the charger still connected try to turn on the phone. If the issue does not occur then it’s possible that it could be caused by the battery. If this is the case then you should get a new battery.

Another possible reason why this problem exists is because of a glitch in the phone data or software.

To troubleshoot this scenario you need to take out the battery and microSD card ( if you have one attached). Press and old the power button for at least a minute then reinsert just the battery. Turn on your phone in recovery mode then wipe its cache partition. This will delete the temporary data in your device. Restart your phone then check if the problem still occurs.

If at this point the issue still occurs then you will need to backup your phone data then do a factory reset. The best way to do a factory reset is through the recovery mode. If you are unable to access this mode then the issue could already be hardware related. If this is the case then you should have you phone checked at an authorized service center.

Samsung Note 4 Shuts Off When Snapchat Is Used

Problem: My Samsung Note just shuts off whenever I open the Snapchat app. And when I try to turn it on, it just keeps shutting off and turning on, on its own. The only time I’m able to fully start it, is when it’s plugged into a charger.

Solution: This issue could be caused by some form of corrupt data in your phone. Try clearing the cache and data of the Snapchat app then uninstall it. Start your phone in recovery mode then wipe the cache partition of your device. Restart your phone normally then download a fresh version of Snapchat from the Google Play Store. If the problem still occurs backup your phone data then do a factory reset.

If the issue remains then try getting a new battery.

Samsung Note 4 Continuously Turns Off

Samsung Note 4 Continuously Turns Off

Problem: My phone continually turns off and on regardless of the charge. I have tried a soft reset and have also done a factory reset. I have also recently gotten a new battery.

Solution: If a factory reset fails to resolve the problem then this could be a hardware related issue. You should however check if the issue occurs even when your phone starts in recovery mode. If the issue does not occur in recovery mode then the problem could be with the phone software. You should consider flashing your phone with an updated stock firmware. Instructions on how to perform this procedure can be found at several of the popular Android forums online.

If the issue occurs even in recovery mode then I suggest you have your phone checked at an authorized service center.

Samsung Note 4 Turns Off Everytime Camera Is Used

Problem: My Note 4 turns off everytime I use my camera. It never turns on until I connect the device to the charger. And my battery never gets fully charged, it just stays in 80%. Plz help

Solution: Try checking first if a third party app is causing the problem by starting the phone in Safe Mode. In this mode only the pre-installed apps are allowed to run while apps you downloaded are disabled. Check the camera in this mode. If the issue does not occur then an app could be causing the problem. Find out what app this is and uninstall it.

If the issue occurs even in Safe Mode then proceed with a factory reset. Take note that you should backup your phone data before doing this procedure.

If the issue still occurs after a factory reset then the problem could be caused by a faulty hardware. Try replacing the battery with a new one. If this doesn’t work then have your phone checked at an authorized service center.

Solution: It looks like the battery of your phone is already faulty. Try backing up your phone data first then do a factory reset. Once the reset is done do not install anything in your device yet. Check first if the issue remains. If it does then proceed with getting a new battery.

Samsung Note 4 Does Not Hold A Charge

Samsung Note 4 Does Not Hold A Charge

Problem: My phone will not hold a charge..it will only stay on when plugged into outlet otherwise it would turn off and turn self back on continuously on its own. Now it wont stay on for anything.

Solution: There’s a possibility that this issue could be caused by a weak battery. Try getting a new battery first then check if the issue gets fixed.

If the problem remains even with a new battery then charge your phone for at least 20 minutes before turning it on. With the charger still connected turn on your phone then backup your data. Once a backup has been made I suggest you do a factory reset.

Samsung Note 4 Charges Slow After 80%

Note 4 Charges Slow After 80%

Problem: Recently my note 4 charge really slow after 80%, and stops around +/-85%, secondly, the battery can only stand till 10-20%, the phone will automatically switch off. Recently I notice also, before it switch off, my phone will deactivate all my phone line, once start charging, the phone line will be back to normal. Lastly the problem that I am facing is also, when my phone is 10-20% battery, I plugged to charge, the battery will 1st decrease the % to 0%, after that it will only start charging like normal 0-85%.

Solution: It appears that your phone has a faulty battery. Try replacing this battery with a new one then check if the issue still occurs. If it does then follow the troubleshooting steps listed below.

• Use a different charger and charging cord. While this may not resolve the issue of your phone turning off on its own it will address the slow charging issue that you are experiencing.
• Clean the phone charging port with a can of compressed air or cotton bud dipped in alcohol. Again, this is meant to address the slow charging problem.
• Backup your phone data and do a factory reset. Sometimes if a phone turns off on its own it means that there is a problem with the phone software. A reset is highly recommended in this case.

Samsung Galaxy Note 4 Will Not Charge Issue.

Note 4 Will Not Charge

Problem: I just paid $470 for my new Note 4 and it will not charge to 100%.  I will plug it in at night at 60% and by the time I wake up 6-7 hours later it’s only at 70%.  It says it’s fast charging. I am using the cable that came with it.  The “fast charging” section is checked.  My husband is already pissed I already spent this much on a new phone….any help would be awesome!

Solution: If this is a new phone then it should be able to charge properly unless there are issues with the hardware or software. Even with fast charging not checked the phone should charge to 100% in a span of 7 hours.

The first thing that you should check in this case is to verify if the charger is getting continuous power from the power outlet. Try charging your phone from a different outlet then check if the battery charge rises.

The next thing you should check is the charger itself. Sometimes, even if the charger is new, it will have some issues. Try using a different charger and different charging cord when charging your phone.

Moving to the phone itself, a software issue can also cause the device to charge slowly. In this case I suggest you backup your phone data then do a factory reset. Once the reset is complete do not install anything in your phone yet. Instead, charge your device and check if the problem disappears.

If the issue remains even after a reset then you should consider returning the device and asking for a replacement if it is still under warranty.

Samsung Galaxy S4 Can’t Access Wi-Fi

Problem: I have 2 of these phones. They are currently locked until I pay off the bill. I was told that I can still use these phones as wifi only. I plan to use them for music or podcast downloads. However…no matter what I do…I can’t access any wifi services. How can I use these phones? I can’t find anything on the internet that helps me. Thank you.

Solution: Make sure to turn on the Wi-Fi switch of the phone then let it scan for any available network. If you see your network in the list then connect to it. You may need to enter the network password. Once connected the phone should be able to go online.

Samsung Galaxy S4 Wi-Fi Keeps On Asking For Password

Problem: My WiFi keeps on asking for a password again and again.I would like to attach some screenshots of the settings of the advanced WiFi settings.

Solution: Try forgetting the Wi-Fi connection then connect to it again. If this does not work then restart your phone and the router. Try connecting to the Wi-Fi network again the check if the issue still occurs. If it does then start your phone in recovery mode then wipe its cache partition. This deletes the temporary data stored in your phone that could be causing the problem. You should also try connecting the phone to a different Wi-Fi network to check if the problem is caused by the router you are trying to connect to.

If the above troubleshooting steps fail then I suggest you backup your phone data then do a factory reset.

Samsung Galaxy S4 Not Connecting To 3G

Samsung Galaxy S4 Not Connecting To 3G

Problem: After a factory reset done due to full internal memory, the 3g has stopped working! The icon is turning green but the mobile is not connecting and the mobile is not receiving the configuration message from the operator as well. Before the message was arriving immediately. The connection is configured well manually and the sim card is working in 3g with my old galaxy s3 mini. Thanks

Solution: Since you can connect to mobile data when the SIM card is transferred to another device then we can eliminate any account or network signal related problems that can cause this issue. The most probable cause behind this is that the APN settings of your phone does not match the one you network is using. I suggest you compare your phone APN settings to the one your network is using then make the necessary changes if needed.

Samsung Galaxy S4 Auto Connect to Wi-Fi Option Missing

Problem: Hello there. I have a Samsung Galaxy S4 mini GT-I9195 Android version 4.4.2. For some time I have the problem of losing WIFI password. I was happy to find a solution in your article about this: http://thedroidguy.com/2013/08/galaxy-s4-asks-for-wifi-password-every-time-wifi-turns-itself-off-automatically-70074.

Problem: My wifi will not enable, I try to turn it on, the phone thinks for a min then shows wifi as off. My blue tooth also does the same thing. I have factory reset the phone several times, tried safe mode, still same issue. Please help!!!!

Solution: Unfortunately this issue looks like a hardware problem already. The Wi-Fi and Bluetooth of your phone is handled by a single IC and a single capacitor.

Samsung Galaxy S4 Freezes When Making A Call

S4 Freezes When Making A Call

Problem: During a call, the mobile will act like it has no signal even though it does, and it will freeze when I try to end the call, so I have to restart the screen.

Solution: Have you tried to check if the issue occurs when your phone is connected to its wall charger? If it doesn’t occur then the problem could be caused by a weak battery. Get a new battery then see if this fixes the problem.

Some form of corrupt data in your phone could also be causing this problem. Try to wipe the cache partition of your phone from the recovery mode then check if the issue still occurs. If it does then I suggest you backup your phone data then do a factory reset.
