Problem #1: Galaxy S6 won’t turn on when power button is pressed | Galaxy S6 screen becomes unresponsive randomly after an update

I have just applied the update that my Galaxy S6 has been hounding me with after about a week of hitting the update later button. However, my phone is now giving me multiple troubles. The phone does not turn on immediately after I hit the power button and any command that I try is either completely ignored or only occurs after a minute of the screen being frozen in place and not responding to anything else. Other times, it will act as if I turned it off and back on or it may just close the app that I am using or turn off completely for no reason. I can’t tell if it is the update or if there is another reason, but I want to fix my phone and not have to get a new one. — Nathan

Solution: Hi Nathan. If this issue started after installing the latest update, the usual dose of software troubleshooting may help.

Refresh the system cache

The first potential solution that you want to try is to ensure that the system cache is updated. Sometimes, updates can corrupt the system cache, resulting to all sorts of issues afterwards. You need to delete the old cache to make way for a new one. 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.

Update apps

Having a good system cache won’t matter if the issue is due to an incompatible or even a bad app. Make sure that ALL your apps are compatible with the operating system. Uninstalling old or unused apps is always good practice but it’s all the more important after you notice issues following an update. Not all developers are keen on updating their apps so there’s always a chance that you may have installed a buggy one. Stick to official or popular apps as they tend to have lesser problems than those built by unknown developers. Inexperienced developers, most of the time, commit coding mistakes that can be carried over after updating an operating system. Don’t fall into the same mistake many Android users do after a system update — not to update apps. System updates are modifications to the operating system but not to apps. Apps must be compatible with the new Android version in order to work in harmony within that complicated web of software environment. Failure to do so is the main reason why there are a lot of people whining about a new OS version.

Try to read reviews of other users if you are not sure if an app is compatible or not. You can also try to contact the developer directly.

Observe the phone in safe mode

If updating the apps won’t change anything, the next logical step that you can do is to restart the phone to safe mode. Doing so will help you see if one of the installed third party apps is responsible. Safe mode blocks post-unboxing apps and services, making it a good tool to use if you suspect that an app is problematic. To boot to safe mode, follow these steps:

  • Press and hold the Volume Down and Power keys for 20 to 30 seconds.
  • Once you see the Samsung logo, release the Power key immediately but continue pressing the Volume Down key.
  • Your phone should continue booting up and you will be prompted to unlock your phone as usual.
  • You will know if the phone successfully booted in safe mode if the text “Safe mode” is displayed at the lower-left corner of the screen.

Remember, safe mode will only tell you if a third party app is causing trouble in a general sense; it won’t identify the particular app. You must do some follow up if you want to get to the bottom of the issue by individually removing apps and observing the phone after each uninstallation.

Wipe the phone clean via factory reset

Finally, if nothing appears to work, the last potential solution that you can try is factory reset. As the name suggests, factory reset will bring all phone software settings back to their factory state. This will allow you to compare how the phone behaves when there’s virtually nothing new to the system and when you have everything installed as it is at the moment. That said, make sure that you observe the phone for at least 24 hours after a factory reset. If everything appears normal, that’s proof that a glitch may have developed after the update you installed. If nothing changes though and the same symptoms remain, a hardware problem may be to blame. In this case, you must consider having the phone’s hardware examined or replaced.

To factory reset your S6, follow these steps:

  • Turn off your Samsung Galaxy S6 Edge.
  • Press and hold the Volume Up, Home and Power keys together.
  • When the device powers on and displays ‘Power on logo’, release all keys and the Android icon will appear on the screen.
  • Wait until the Android Recovery Screen appears after about 30 seconds.
  • Using the Volume Down key, highlight the option, ‘wipe data/factory reset’ and press the Power key to select it.
  • Press the Volume Down button again until the option ‘Yes — delete all user data’ is highlighted and then press the Power key to select it.
  • After the reset is complete, highlight ‘Reboot system now’ and hit the Power key to restart the phone.

Problem #2: Galaxy S6 stops charging via USB cable

About a month ago my phone screen would turn into this rainbow and my phone wouldn’t charge one bit. I tried many different chargers. A few hours later it worked like nothing happened. Yesterday night when I left my phone unlocked the rainbow screen would pop up again and I would tap the screen and it went back to normal. Around 8, I was charging my phone on my little travel charger until it died so I plugged it into my regular charger and it wasn’t working. So I tried a few more chargers and it didn’t work either. It’s now noon of the next day and I’ve been charging it wirelessly and its only at 82%. I’ve thought about resetting it completely, or go take it to a repair place. I just don’t want to spend the money if it’s an easy fix. — Alexia

Solution: Hi Alexia. Doing some basic software troubleshooting first might indeed you some money, provided there’s no hardware malfunction involved. If your phone’s software has simply encountered an unknown error, the software solutions we mention in this post might help. Because the issue seems to appear out of nowhere, we recommend that you try booting the phone to safe mode first so you can compare how charging works when third party apps are disabled. Refer to the steps above on how to boot to safe mode.

Should safe mode won’t make any difference at all, don’t hesitate to do a factory reset to wipe everything on the phone’s internal storage device. Of course, as mentioned above, it would also bring all software settings back to their default state. Make sure that you try wired charging after a factory reset so you’ll see if it works or not. If the same issue occurs and the phone refuses to charge via cable, you can assume that the charging port may be defective, the battery stopped working, or an unknown hardware issue is causing trouble. In any case, you would want to have the phone’s hardware checked. If it’s still in warranty, try to see if you can have the unit replaced instead.

Problem #3: Cannot uninstall ShutApp from Galaxy S6

Hello. I am having a problem with an app that I downloaded. It was downloaded from the Google Play Store. It is called ShutApp. It is basically used to shut down background apps that are running. The problem is when I try to uninstall it, it tells me that the app is a device administrator and needs to be deactivated before it can be uninstalled. I try to turn it off as a phone administrator, but it will not allow me to do so. Shortly after attempting to turn administrative rights off, I get an error message stating, “Unfortunately, settings has stopped.” There is no way to get this app off of my phone. Any, and all help on getting rid of this rogue app would be appreciated. I am trying to avoid doing a factory re-set. Thank you in advance! — Pete

Solution: Hi Pete. There are generally two ways to uninstall an app from an unrooted phone. One is via apps list in your Google Play Store app, and the other is via Application Manager under Settings. If you’ve already tried both methods before, try using other third party uninstaller apps such as Easy Uninstaller App Uninstall or Uninstaller. If third party uninstallers won’t work either, just do a factory reset.

Problem #4: Water-damaged Galaxy S6 won’t turn on

I left my Galaxy S6 in my bag with a water bottle and the charger. i opened it a few minutes later to see that the water bottle opened up and wet my phone and charger. I dried the charger then removed the phone case and dried it. i soaked it in rice and didn’t try to turn it on. i checked the charger on another phone and it worked (which gives a little hope). but since the phone is a Galaxy S6, i couldn’t remove the back, so i couldn’t really dry the battery. After soaking the phone in rice for almost 4 days, it refuses to turn on and wont charge but i could feel the phone heating when i tried to charged it although the screen didn’t show anything. i looked into the SIM slot and i don’t see any pink or red color and I really don’t know what to do. Is it hopeless? — Celia

Solution: Hi Celia. We hate sugarcoating in a case like this so, yes, the situation is hopeless. The Galaxy S6, unlike the S5 and the S7, does not have an extra layer of dust- and water-resistance (IP67 certification for the S5, IP68 certification for the S7 and S7 edge) protection. In other words, the Galaxy S6 soaks up whatever water or liquid thrown at it. If your phone no longer turns on at this time, some components must have stopped working at this time due to water damage. The best thing that you can do right now is to have the hardware dismantled and examined. There’s no way someone can help you. Forget about fixing a water-damaged electronics yourself. Unless you have the necessary tools and knowledge to check every major component in the motherboard, self-help repair is really out of the question.

Problem #5: Galaxy S6 keeps freezing and screen turns black

Hello. My boyfriend recently got me the Galaxy S6 for my birthday (around 2 weeks ago). The first week it was working perfectly fine but the second week is when things took a major turn. The phone would freeze to the point where I have to do the maintenance boot (volume and power button) because it refuses to turn off with the power button. The phone randomly restarts whenever it feels like it and sometimes, the screen turns black but the LED light is still blinking. I do not know how to fix this problem or what caused it. It has not been dropped nor does it have any water damage. I also went to Verizon but they didn’t help besides suggesting a third-party place to fix it. Thank you. — Angela

Solution: Hi Angela. Telling us that your phone randomly restarts and the screen sometimes turns black is like telling your doctor your stomach aches without giving him more background details such as things you ate and drank before. The symptoms you’re describing here can be caused by anything. Technicians like us needs more information like things you did to the software that may have led to the problem. Without enough background information, there’s just nothing that we can do to help you identify the problem. Please get back to us with more information. We’ll update this post once we received additional details.

In the meantime, you can try doing a factory reset to see if that will make any difference.

Problem #6: Galaxy S6 edge keeps saying SMS sending failed

I have a Galaxy S6 edge. My text messages are giving me a hard time. After i sent out a vast amount of texts saying happy new year to people and got some people to respond back, when i try and text them again it tells me that it failed to send. I tried sending a text to myself and it said it failed to send but after maybe 5 minutes it then was sent back to me. I also sent a text to my mom who was sitting next to me in which it said message failed sending but she got my text right away. I also had messages come twice or more from the same person after it was already sent to me. Yes i am receiving text messages tho. Is this just because i shouldnt have sent out so many texts and my phone is trying to keep up with me or is there something else i can do. Thanks! — Yvette

Solution: Hi Yvette. This is either a network glitch or an issue on your phone. To see if it’s a device issue, try to wipe the cache and data of the messaging app. Here’s how:

  • Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  • Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6.0.
  • Once in there, click on an application.
  • You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
  • You should now clearly see the Clear Data and Clear Cache buttons for the application.

If nothing changes after doing this process, contact your carrier and ask for direct assistance.

Problem #7: Galaxy S6 unable to receive incoming calls and text on FreedomPop network

I bought a Samsung Galaxy S6 refurbished phone 3 months ago from Freedom Pop which operates over Sprint towers. It works fine while on WIFI, but won’t accept incoming calls or texts with it off. I have to have a WiFi connection or nothing. Data is on using 4G LTE and 3G connections with a strong stable signal. Outgoing calls and texts work perfectly without WiFi on while using cellular connections.

Reading through your other posts, I have booted in safe mode with no changes in incoming call/text status. I also wiped the cache partition successfully. Still no difference. Incoming only with WiFi, outgoing either WiFi or cellular service works. Service selection switch off as per posts.

Freedom Pop customer service now costs $10 per 5 minutes. Used to be free before 7/1. Other than the above, everything works perfectly. I’m really not sure if this phone ever worked on incoming cellular calls because I rarely get calls or texts. I just figured out this problem a couple of days ago when people wondered why I didn’t answer their calls or respond to texts. Hummm.

Any suggestions to get ‘er going so I can receive calls/texts when there is no WiFi available? I would really truly  appreciate any assistance! Think it might help to go with Consumer Cellular instead? Thanks in advance for any and all assistance!! — Dennis

Solution: Hi Dennis. Like it or not, you really want to direct your questions to FreedomPop support and not to third party technicians like us. We have no idea how their services work and if there are some special configurations that you need to set up first. We’re thinking the problem may have something to do with how wifi calling is setup on your device so make sure to mention that when you call them. We also know that there are at least two apps that you can install from them so you might want to also check them out. These apps are:

  1. FreedomPop Messaging Phone/SIM, and
  2. FreedomPop OTT Call and Text

Again, we are not familiar with how FreedomPop’s services work so make sure that you let them know about your issue.

A quick Google search about FreedomPop issues provides some reference. You can start checking this knowledgebase out: How do I make calls and texts?
