My phone went completely dead last night while carrying it in my purse pocket. I had used it prior to putting it into my purse and when I took it out it was completely dead and would not turn on but I know that it had battery life. I tried to charge it with three different chargers so I know it was not the charger. I did get the phone to turn on with the volume up button and power button but it only shows the charging icon and a dark blue/light blue flashing light. It does not look like it is adding any charge. I pressed the volume down, power and home button and it shows the Galaxy S6 screen but that is all. It is stuck, any suggestions? I don’t really know what the Android Version is, I was guessing with Lollipop. — Deb
Solution: Hi Deb. There are a number of failures that can lead to an issue like this. Below are these possible causes:
- dead battery
- malfunctioning motherboard
- broken power button
- unknown software glitch
As you notice, the first three in the list are all hardware causes. If any of them is the main cause, the next best thing that you can do is to seek help from a professional. You may ask how do you determine if hardware is to blame. Well, it’s actually simple in this case. You just have to try to boot the phone to alternate modes by following the steps below. If the phone remains unresponsive, or if you can’t, for example boot to any particular mode to do a follow-up procedure, that’s proof that hardware is to blame. Here are the steps on how to boot your phone to different modes:
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.
After last system update, 1 out of my 100 contacts is not getting my texts, but I get his just fine. Mine say “sent” but not delivered, like the rest. When I go to text him, instead of the grey record microphone to the right of the “type message,” it’s blue. When I start to type, it turns into that send arrow & says “chat” instead of “SMS” like all the others. And it’s still blue, unlike the grey on the others. I tried rebooting my phone, uninstall/install, deleting the contact & reentering the contact, but it hasn’t helped. I did the text update & this did not help. I uninstalled the updates on the app & now my messages for this contact says “sent” not delivered, like the rest. I downloaded a different app & he got my message, which is great, but I really want to use the Verizon message instead. — Coldnosekennels
Solution: Hi Coldnosekennels. If you can send SMS fine to this contact using another app, that’s a clear sign that the Verizon messaging app is problematic. Make sure that you let Verizon know of the problem so they can let their app developer team about it. An issue like this may or may not have immediate solution so make sure that you let Verizon know about it.
Good Morning. Last night my phone froze and restarted itself randomly about 6 times until it completely turned itself off. I tried charging it, tried the soft re-set, turning it on etc. and none of it has worked. I was wondering (more like hoping) that it’s a simple issue to fix and some other people I’ve tried asking for help (so called ‘gurus’ were no help at all). I’m quite worried, more so about all my files, photos etc (memories we’ll call them) and losing them. Because I’m not certain that I’ll be able to transfer all the files if the phone can’t be fixed. I hope you are well, and that you’ll be able to provide some light on this issue. Kind Regards. — Elizabeth
Solution: Hi Elizabeth. Your issue is similar to Deb’s above so kindly refer to our suggestions for her. Keep in mind that your main task here is to see if you can boot the phone back on to any alternate mode. Even if, for example, you will be able to turn it on to download mode, there’s no guarantee that you may be able to recover your files because you can only do that when the phone is either in normal mode or safe mode. The Nand chip, or the storage device in your phone requires power and a working operating system so a user can access its content. If the phone remains unresponsive, there’s no way you can get your files back.
Hi and good morning. My issue on my Samsung Galaxy S6 edge is not charging even if i left it plug in for several hours. It is still not showing sign of charging. I check the charger and cable and there’s no problem in them. It started last night. seems perfectly working. i left it with a 30 percent battery life with wifi on and mobile data is off. And i woke up 5 hrs later and when I look at my s6 edge, it’s completely off no matter what combination of pressing the button i did. I search on the troubleshooting guide on the internet still no success to power it on while the charger is plug in to the wall. My S6 edge is running on official Android Marsmallow 6.0.1. And i take care of it very much. no scratch never been dropped. Hoping very much that you could find a solution for my device and very much appreciate it. Thank you. — Mikeyutuc
Solution: Hi Mikeyutuc. Sometimes, a pin inside the charging port can be bent due to misuse or wear-and-tear so make sure that you inspect it with some form of magnification. Try to look for signs of damage and see if there’s something that you can do to fix it yourself (such as straightening a bent pin). If everything looks normal inside or if you can’t inspect it thoroughly, try the suggestions we provide for Deb above. If you won’t still be able to power the phone back on, have the phone repaired or replaced.
Recently my Samsung S6 had an update notification that I clicked to install. Usually I’m cautious about updates, because they cause problems. The standard updates were fine to this point. I presumed it was for the operating system. This particular update also FORCED updates for ALL my applications INCLUDING Gmail. Arggh!! I want to revert back to my old Gmail that I have had for the last 2 years. It worked just fine and I purposely did not update it when notified.
I had 3 updates including GMAIL that were pending and I chose NOT to update them, because the old versions worked just fine. I am most upset about the update to my Gmail though. However, I guess under settings I did not have the “do not auto update” selection active for some reason. I remember having it before, but they must have changed that feature in previous updates because I looked at it after the fact and it was not set to NOT update. So I got stuck with having my Gmail updated without wanting it to.
In this case my Gmail was updated into this awful version with a bunch of colored icons that takes up too much real estate on my phone screen. It’s just terrible to use. Stuff is hidden and hard to find. I don’t like it AT ALL. I really really want my previous older version back. I called the Google App store support and we tried to uninstall the updates from the settings and application manager and then clear the cache and restart. It didn’t work. The new version was still there. We tried disabling and re-enabling the Gmail app. The new version persisted. I also called Samsung support. They said because it is a third party application from Google they can’t change back to the old Gmail. I am trying to get back my previous version of Gmail, in whatever way I can. So I thought to ask you if you had any ideas as to what to do. — Expotube
Solution: Hi Expotube. Android and apps evolve so as long as you keep your phone connected to the internet, there’s always a chance that it will receive unwanted updates.
As far as reverting apps to their factory state is concerned, the only way to do it is by disabling or clearing their data under application manager by doing the following steps:
- 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 you don’t want to use the default version of the current Gmail app, you can try to manually flash the older version of the operating system. For example, if your phone is now running Android Marshmallow but you want the Gmail app version of the Android Lollipop OS, you can flash the older OS to your phone via Odin mode. Keep in mind that flashing, if not done correctly, can lead to problems. We don’t recommend that you do it on your phone but if you can’t live without the old Gmail app version, this is your only choice.
We don’t provide step-by-step guide in flashing any device so use Google to search for one.
Hi. I was wondering if you guys/gals could help me. I have a Verizon Samsung Galaxy S6 (4G LTE), unlocked when received. I used it with Consumer Cellular (AT&T network) for a year with relatively few problems. It can no longer connect to the AT&T network. My friend had factory reset it before giving it to me. Toward the end of the year, the network would cut out every so often for a day or two at a time. As of January 3rd 2017, the network cut out completely. Confusingly, testing a friend’s Verizon SIM card in the phone got me full bars and I could call people. I’m wondering if the problem is that it is not updated to Marshmallow. AT&T said they phased out their 2G towers as of Jan 2017, but the phone should be able to go to 3G / 4G. I have always had it on global network mode. (The other 2 options are “LTE / CDMA” and “GSM / UMTS”. Neither gained access to AT&T network after January 2017).
I factory reset it a few days ago. Unsurprisingly, I still can’t access AT&T’s network, but my friend’s Verizon SIM still works, full bars. When I called Verizon, they said they can’t unlock it remotely and that phones have been known to spontaneously lock themselves. Is there any way to unlock the phone again? I’m leery of rooting it, that’s my last option. The phone is not reported as lost (bought from my friend) It has not been Rooted. Thank you for taking the time to read this! — Aleksandra
Solution: Hi Aleksandra. There are only two possible causes for this problem. Either (1) the phone’s software or network settings have been changed, or (2) there’s a problem with AT&T’s network services in your area.
The first one usually happens if a ported phone like the one you have, which is a Verizon phone, is updated, rooted, or flashed. In some cases, doing a master reset, a type of factory reset via recovery mode, can revert the original network settings of the phone, which in this case is Verizon’s. if you did an update, rooting procedure, flashing or master reset on the phone prior to noticing the problem, that may be the reason why the phone can no longer connect to AT&T network. To fix it, you must ask your friend again what changes were made on the phone before it was given to you. Verizon phones are notoriously difficult devices to configure so they can be used with other networks. If you did not do anything after you received it from your friend, ask him or her what else she tried other than factory reset that made it compatible with AT&T network.
Otherwise, talk to AT&T technical support and ask for direct assistance. There may be an on-going issue that affects users in your area.
