Problem #1: Galaxy S6 “USB device not recognized” error

I rooted my phone using Odin a few months ago. Then it just crapped out on me. Now it is stuck in a boot loop mode. I can get it to recovery mood and download mode. I have tried wiping the cache partition and done the factory rest. That isn’t the issue. The issue is that when I have Odin open the phone isn’t being recognized. it keeps saying “USB device not recognized. the last USB device you connected to this computer malfunctioned, and Windows does not recognize it”. I have tried reinstalling the drivers for my Sprint S6. I have also updated the media package for my windows 8.1. But it still isn’t recognizing the phone. I also tried un installing and reinstalling. I have smart switch but still nothing. I am not entirely sure how to fix this. Please Help!!

Also, in the top left hand corner where it says “[kernel is not seandriod enforcing. custom binary blocked by frp lock” I am not entirely sure what version of Andriod lollipop i have. I am pretty sure it is the most recent. Please please please help. I am desperate.  — Pari

Solution: Hi Pari. First of all, you have to know that your phone has triggered the FRP lock feature, which means that you can no longer perform any software modification unless you supply the correct Google account credentials. We’ve written a short explanation about what FRP is previously so please follow this post if you want to know what to do.

Secondly, since the computer you are using right now does not recognize the phone via USB connection, consider using another PC to the job. Using another USB cable will not also hurt. We’ve seen some few cases before wherein bad USB cables trigger the “USB device not recognized….”  error.

Problem #2: Galaxy S6 not charging

Hello. I am unable to charge my S6 Edge that I’ve purchased in May 2016. The device has already turned off. When I’m trying to charge it, i am seeing the charging icon, but it is not filling up. At times, I am able to switch it on. But once it reaches to the point where I have to enter my password, it just switches off. While it’s on, I am able to notice the small battery icon which indicates 0% and not charging, even though i’m charging it.

I’ve tried charging other devices with my Samsung charger. It’s working perfectly. I’m also tried connecting my device with my laptop with the same unsuccessful results.

Please try to enlighten me on the matter. Thank you. — Sidrah

Solution: Hi Sidrah. Try charging your phone wirelessly if possible. Should the issue remains even when being charged wirelessly, there must be a problem with the hardware or battery. Make sure to have the phone checked by Samsung or simply ask for a replacement.

Problem #3: Galaxy S6 not booting up properly due to water damage

Literally dropped the top of my phone into a half drinken cup of tea (no sugar and with soya milk) for a split second wiped it all down. it had a clear plastic case on the back that I removed and wiped down. Phone was phone and working completely normal then checked and it wouldn’t turn on at all. Placed in a bowl of rice for 24hours. Phone now won’t charge but the screen comes on and starts up normal but when gets to the home screen it says 0% battery and the dies. When I plug in the charger it just shows the battery with a lightening bolt and the shows 0% but won’t charge. I brought a wireless charging pad that shows blue on the charger but nothing on the phone. Only will turn on with the charger in it but won’t actually charge. Hope this is enough information! Phones only a month old! — Maddie

Solution: Hi Maddie. Some liquid may have found their way into sensitive components of the motherboard causing damage to the phone. The best thing that you can do right now is to have the device checked by Samsung or a third party shop.

Keep in mind that liquid- or water-damage voids whatever warranty you have left on the phone. This means that you will have to pay Samsung if you want them to fix the issue for you. Water-damage can also potentially knock down the entire motherboard, even if only a couple of parts are affected. Motherboard replacement of an Android device is basically expensive and may not guarantee full functionality of the device so it’s actually a big gamble. If you can no longer boot the phone normally at this time, you may have to consider replacing it eventually.

Problem #4: Galaxy S6 memory keeps getting full

The first thing is I really think when they synced my old to the new I think I have double apps.  I’m not really sure what I need to keep or what to delete. I first got the 32G, and it totally locked up within 2 days my memory was full.  It would not do anything.  I came from the Flex & had around 2% of memory never had a problem. I think it was a 24G. Never made since and they wanted to delete my pictures. They traded up to the 64G & now it tell me it’s almost full. 

I don’t play games, but I take quite a few pictures of my granddaughter.  I like to craft so I like some documents to print templates, love P, some Facebook not much, Instagram not much, YouTube about like P.  To see the DIY’s.  But I have Wi-Fi and a signal extender.  I can see that it keeps switching from WiFi to the network, and at times it shows both.  This drives my data crazy. I’m not out much so I should stay on wi-fi.  So why do we keep going over our limit which is quite a bit?

I’m so confused and really would like to throw this thing out the window while going down the highway.   Never had this must trouble with my Flex. I loved it though this would be a great Christmas present. Got it the week of Christmas.  So what the****? — Lorrie

Solution: Hi Lorrie. The Galaxy S6 is a great phone if it works properly so let’s see how we can fix the mentioned issues one by one.

First off, you need to manage your phone’s storage properly so the primary internal memory does not get full in a short time. Checking what stuff are consuming your storage space should be your first priority. You can do so by doing the following:

  • On the Home screen, tap Apps.
  • Tap Settings.
  • Tap Storage.

Under Storage section, you should see a breakdown of the things that compose the device memory space. Touching a component in this section, for example, Miscellaneous files, will give you an option to delete it. Make sure that you delete any redundant or unnecessary large files here.

For the second issue, make sure to turn off mobile data when you’re at home to avoid going beyond your subscription threshold. This will force the phone to stick to Wi-Fi at all time.

If you enabled Smart Network Switch feature, we also suggest that you turn it off. Smart network switching is a feature that tells the phone to automatically connect to mobile data if Wi-Fi signals are weak to maintain internet connection. To turn it off, just follow these steps:

  • From the home screen, tap the Apps icon.
  • Tap Settings.
  • Tap Wi-Fi.
  • Tap MORE.
  • Tap Smart network switch.
  • Tap On or Off to enable or disable as required.

Problem #5: Galaxy S6 restarting on its own

I recently had to reset my S6 because I was informed that my CM security app me a hefty virus. Everything was fine until the next morning when my text would not send so I restarted my phone. then it showed all of my apps were uninstalled. They eventually came back but Facebook would freeze when I opened it. So I uninstalled it and came to the exact reason that I reset it in the first place. It would download to 95% but the phone thought it had downloaded fully. I popped out the SD card and shortly it fully downloaded.

Now I have a new issue. Any app that is running and in my status bar cannot be opened if I pull down the bar and select it. It’s very annoying. Also, if the phone goes to sleep while an app is open then hit the home button to turn it on, the phone bypasses the lock screen and goes straight to the home menu. I believe the lock screen works if I manually turn of the phone or go home then turn if off. The phone also shuts off by itself but I turn it back on. Please help me if you can. Thank you! — Dan 

Solution: Hi Dan. Looks like you have a corrupted operating system. Make sure that you perform a factory reset to quickly bring things back to normal. Factory reset will erase everything off the phone’s internal memory device so make sure you create a backup of all your files before proceeding. If you haven’t done a factory reset before, simply 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.

Since we are dealing with a possible virus issue via an app, we suggest that you take your time installing third party apps next time. Make sure that you only install trusted apps from Google Play Store. If you notice problems after installing an app, you can also boot the phone in safe mode. If the issue fails to occur in this mode, that means that one of your apps is to blame. Make sure to uninstall it right away. If you can’t identify which app is the culprit, simply do another round of factory reset and install apps individually. Then, try to observe how the phone behaves after each app installation so you will have time to see if that app is problematic.

  • To boot your S6 in safe mode, these are the 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.
