Problem #1: Galaxy S7 “Touchwiz not responding” error

I have Galaxy S7 for several weeks now, running Marshmallow 6.0.1. Battery is not removable. Problem occurs in the middle of running an app. it just reboots on its own and then I get the “process not responding” and “touchwiz not responding” messages.

I have done several “wipe cache” actions, and the problem does not go away. If I select “Wait”, it eventually restores Touchwiz and all the icons. I have also tried Good Lock, which is supposedly a good launcher, from Google but the problem continues, telling me that “Touchwiz isn’t responding” even though the default is Good Lock.

I have removed many apps that I wasn’t using, always “close all” after I open a few apps.  And I removed CleanMaster, which I thought was taking a lot of battery power. Battery holds up fine, the only problem is this rebooting on its own, and process and “Touchwiz not responding”. It’s not ready for Nougat, yet. Can I revert to version 6.0? — Alice

Solution: Hi Alice. With so many free apps available for download in Google Play Store, it’s not uncommon to find many average users install whatever catches their fancy without considering the risk of creating complications. The general rule when it comes to dealing with Android issues is to keep wary of apps. The less apps you have installed, the lesser the chance of encountering problems. The thing is, there is no way for anyone to know what the offending app may be once problems start to show. The only thing that you can do is to either use A) method of elimination to identify the app, or B) by doing a factory reset and observing how the phone behaves after you install an individual app.

We recommend that you do B (factory reset) so you can effectively isolate the problematic app. Doing so takes time as you need to observe your device after every app installation but it’s the better method if you are really intent on identifying the reason for your problem. Make sure that you don’t install everything at once after a factory reset to ensure that your effort pays off.

For reference, here are the steps on how to do a factory reset on your S7:

  • Turn off your Samsung Galaxy S7.
  • 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 data / factory reset.’
  • Once highlighted, you may press the Power key to select it.
  • Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
  • Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  • The phone will now reboot longer than usual.

Remember: Factory reset will erase your photos, videos, contacts, and other personal data. Make sure that you create a backup of them before you proceed.

It’s not ready for Nougat, yet. Can I revert to version 6.0? There’s no official way to revert to the previous Android version so you must do it manually via Odin mode. We don’t provide step-by-step guide on how to do it in this blog so find a reputable guide online via Google. Keep in mind that manually flashing a firmware can lead to problems. Do it at your own risk.

Problem #2: Galaxy S7 touch screen issue due to water damage

Hey! I bought a Galaxy S7 in June and within a week the phone blacked out and stopped working. But as I was travelling, I was not able to show it in the service centre but thankfully it started working on its on after 10 days. It was working normally when suddenly the phone started acting up like the screen would go black and show lines and the ear phone jack stopped working and finally the touch screen stopped responding. So I took it to the service centre in July and they said that the phone has been water damaged and won’t come under warranty and refused to replace or fix it for me.

Please advise as to what can be done to get the touch screen to respond again? The screen is coming on properly, If I tap the home button twice the camera opens up and I can click pictures with the volume keys. So basically everything else is okay except the touch screen which is unresponsive. Thanks. — Shreshth

Solution: Hi Shreshth. If you’ve read this post and other similar posts for water-damage issue, you will notice that there’s nothing much that can be done about it. You ultimately need to either have the phone repaired or replaced. Since you’ve already tried the Samsung service route, your only way out now is to hope that a third party repair shop can still save your device. If you’re lucky and, for some reason, the failing hardware is isolated to the screen only, replacing the bad screen assembly may resolve the problem. Keep in mind though that moisture can also damage other components in the long term, especially if water damage is extensive. Screen replacement may allow you to use the phone normally for some time before other damage parts can manifest in other issues.

We don’t know what your expectations are but if you’re hoping that there’s something that you can do on your end to fix a hardware issue, you are mistaken. Unless you have the right tools and experience to disassemble Galaxy S7 components, the best way to fix your problem is by seeking help from a professional. Even repair by a good technician may not also guarantee a fix because water damage can lead to other issues. It will not hurt though if you can invest in a repair at this time so you can boot the phone normally and save your personal data.

Problem #3: Some Galaxy S7 apps won’t connect to the internet

My problems began with my S6 Edge after a system update. 3 apps suddenly wouldn’t connect to the internet and they would say that I was in offline mode. I would also get notifications that said “check network connection and try again” almost constantly. Facebook (a pre-installed app) would say “cant connect right now” and lead me to my settings. I contacted Samsung customer support but they couldn’t fix my problem. I was due for a new phone anyways so I got the S7. I had all of my apps, contacts, photos and such transferred over. The next day I started to have all the same problems all over again. I tried the clear the cache thing that was suggested on here but it didn’t help at all. The whole thing is very irritating so I am really hopeful you guy could help me. — Jessica

Solution: Hi Jessica. Because the issue happens on two devices, the problem must either be due to a firmware (operating system) glitch or something that’s caused by a third party app. If all the affected apps are pre-installed, consider booting the phone in safe mode first. This will allow you to tell if one of your third party application is the culprit. Follow these steps to boot your S7 in safe mode:

  • Turn your Galaxy S7 off.
  • 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.

In the event that other affected apps are third party apps themselves, consider doing a factory reset. Once the reset is done, observe the Facebook app for at least a full day without installing any third party app. Make sure that your Facebook app is updated during the observation period. If Facebook works fine, install the next previously affected app and observe again. Do the same thing on the last app and check if there’s any difference. If all of them works normally, you can bet one of your other third party applications is the cause.

If, on the other hand, the problematic apps behave the same even without installing the rest of your apps, contact their individual developer for assistance.

Problem #4: Gmail in Galaxy S7 email app won’t send to group

I am the captain of a tennis team who needs to email 13 people on my team. I have been unable to send any emails, because while it says “sending”, they do not send. I discovered, the hard way, that no one got my emails, and I finally found them in an outbox with “Failed”. No reason, just unable to send. I use the Samsung email app, but I have a Gmail account. I have tried to send it within email, and also in the Contacts app for groups (“Send email”). No matter how I’ve tried it, it ends up in the Outbox. I use my phone most of the time, and have to contact these people at least 3 times per week. I deleted the group and recreated it, with no difference. How do I fix this? — Joni

Solution: Hi Joni. First off, you need to make sure that your Gmail account has no issue with sending emails. You can check this by sending the same email you tried to previously send to the same set of contacts. Use a computer to do this so you’ll see the difference. Once you’ve established that your Gmail account work as expected, remove the Gmail account from the Samsung email app. After that, configure your Gmail account in the email app again and resend the same message to the group. If it continues to fail to send, send the same message to your own Gmail account. If the same thing happens, consider using another email app or Google’s own Gmail app.

If you don’t want to switch to another email app for the moment, try to check the settings of the current email app and make sure that you change everything back to default. Of particular interest is the Delay email sending option, which can sometimes cause sending errors. If you’re fond of changing things without doing enough thinking for possible consequences, simply delete your email app’s cache and data. This will ensure that you set everything back to default. To do that, follow these steps:

  • Open the Settings menu.
  • Tap Apps (some versions may show Applications or Application Manager).
  • Tap the email app.
  • Tap Storage.
  • Tap Clear Data button.

Sometimes, an email app may find a particular email format difficult to manage and send normally, resulting to errors. If you’ve been trying to send an email with an attachment, try to send without one for troubleshooting purposes.

Problem #5: Galaxy S7 won’t turn back on

Hi. I saw your post regarding how to troubleshoot an S7 that won’t charge or turn on. I tried doing the steps that was in your website, but there’s no improvement on my phone. So I decided to email you, just in case you might give me an answer regarding my problem before I go to a technician.

So, I woke up today with my phone already dead. I was confused as to why it was off, when it was at 70% the night before. At first, it was okay — it turned on, and it was in Safe Mode. I decided to turn off the safe mode so I can use the other apps on my phone. After it came back to its normal state, I was able to use it for a few minutes. But then all of a sudden, it turned off, like it just shut down.

I decided to charge it thinking that it since it turned on, there will be no problem with me charging it. The icon appeared, telling me that it was charging, so I decided to leave it and take a bath. After I came back, my phone was so hot (not just the battery but the whole phone), I disconnected it from its charger. I let it cool off, but now it won’t turn on no matter what I do. Please help me. I thought I might ask your help first before consulting a technician. Thank you in advance. I hope you can answer my email as soon as you can. Best regards. — Elle

Solution: Hi Elle. If nothing happens when you attempt to normally boot your phone at this time, the only other thing that you can try is to see if you can turn it on to Recovery mode or Odin mode. If neither of these modes won’t work, that’s a sign that there may be a hardware issue causing the problem. That means that you must have the phone checked physically so a full diagnostics can be done.

In Recovery mode, you will have the options to clear the cache partition and/or do a factory reset, while in Download or Odin mode, you’ll be able to manually install a firmware. To boot in Recovery mode, here are the steps:

  • Turn off your Samsung Galaxy S7.
  • 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.

To boot in Odin mode, here are the steps:

  • Turn off your Samsung Galaxy S7.
  • 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.
  • When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
