Problem #1: Galaxy Note 5 lock screen options

First time switcher to Android on the back of a Note 5 purchase. For this reason I didn’t realize my phone’s lock screen was “absent” as my phone was being locked (fingerprint in my case) only directly to and from the home screen. I never saw the actual lock screen until I activated Smart Lock using the Bluetooth option.

As soon as this was enabled the screen lock appeared and I guess I found myself in the same position as 99.9% of other Android users.

Needless to say my preference is to unlock directly from the home screen. The closest discussion I could find after hours of web searching which mentions odd lock screen behavior being related to Smart Lock was this thread.

I finally bit the bullet and reset my phone in the hope of reverting back to home screen locking but this didn’t work and alas I’m now stuck with the traditional lock screen.

My question is simple. Is it possible for my Note 5 to recover its original home screen lock screen?

P.S. I do not wish to root my phone. — Patrick

Solution: Hi Patrick. We don’t think we understand what you really want to accomplish here. First of all, lock screen customization options are straightforward. Start by checking out Swipe, then proceed to the rest of other options to see if you can get what you missed after a factory reset.

Secondly, your phone’s lock screen mechanism will change once you enable Smart Lock regardless of which trusted lock you’re using. The “absent” lock screen will now be visible on the home screen if your device is not detecting the trusted Bluetooth device. This is how Google designed it and unfortunately, there’s no way to change it at this time. If you want to revert to the original lock screen set up, simply turn off Smart Lock.

Problem #2: Galaxy Note 5 showing a flashing screen after trying to recover photos

After losing my photos  and videos on my Note, I tried to recover it by Dr. Fone but not only did I not get my files but also phone didn’t boot any more. I tried to re-root it, it comes up but there were a webroot warning (secure anywhere) and a massage that the license has expired.

I tried to uninstall it but in initial process without confirming uninstallation it started to flash and restart. It didn’t help to get better. I don’t know what happened!

1-how i can get rid of this flashing (screen get on and off on secure anywhere) and it doesn’t allow to access anywhere?

2-how can i get back this license?

3-Knox warranty void:0x1 (4)??

Thanks. — Mohsen

Solution: Hi Mohsen. Let’s answer your points individually.

Firstly, the flashing message may be an indication that a software modification has messed up the system. Make sure that you perform a factory reset to restore the default settings of your phone’s operating system. For easy reference, here are the steps to do that:

  • Turn off your Samsung Galaxy Note 5 completely.
  • Press and hold the Volume Up and the Home buttons first, and then press and hold the Power key.
  • Keep the three buttons pressed and when ‘Samsung Galaxy Note5’ shows, release the Power key but continue holding the other two.
  • Once the Android logo shows, release both the Volume Up and Home buttons.
  • The notice ‘Installing system update’ will show on the screen for 30 to 60 seconds before the Android system recovery screen is shown with its options.
  • Use the Volume Down key to highlight the option ‘Yes — delete all user data’ and press the Power key to select it.
  • When the process is complete, use the Volume Down key to highlight the option ‘Reboot system now’ and hit the Power key to restart the phone.
  • The reboot may take a little longer to complete but don’t worry and wait for the device to become active.

Secondly, you have to contact Dr. Fone’s customer support for assistance on how to get the license of their product again, especially if you paid for it.

Lastly, we don’t know if your third point is a question what a “Knox warranty void:0x1”. If it is, this means that your phone’s KNOX Active Protection security protection had been tripped probably by your attempts to flash non-official firmware, or by rooting. Knox is an electronic fuse that tells Samsung if the phone’s software has been modified. Tripping the Knox counter means the device no longer has warranty and there’s no way to reset it back to 0x0 (original status).

Problem #3: Galaxy Note 5 battery drain issue after an Android update

Hi. I have an Note 5 which used to run perfectly on its stock Lollipop OS. But recently I was asked to install updates which claimed to optimize performance. The only thing I noticed after the update was a few apps re-skinned, but then the battery started draining like crazy. The phone gets hot when charged apart from when it is off, and to sum it all up THE PHONE IS ONLY 1 WEEK OLD.

Before the update battery life averaged 30 hours constant use, now I get less than 13 hours. ‘Android System’ takes up most battery and shows it to be consuming 40% of the total power when the screen takes only 12% on high brightness. This is clearly an Android issue, since the battery was perfect and there were no problems before updating. Please help, thank you. — Usama

Solution: Hi Usama. Android updates can serve different purposes like improving user experience, fix known bugs, update security features, add or remove services, among others. In general, they are intended to fix rather than to create problems. The thing is, installing an Android update does not necessarily mean you are updating your apps too. Outdated apps working with an updated Android operating system can be problematic and often results to issues including the one you are experiencing right now. Actually, this is only one of the many potential causes.

Make sure that your apps are compatible with the version of your device’s operating system. Official apps from popular developers or products are often up-to-date. The same cannot be said of old apps or those built by least known developers though. Get rid of apps that you haven’t used lately. A good rule of thumb when it comes to getting rid of apps is by going over all of them. If you haven’t used an app for the last 2 weeks, chances are it is not that important to you. Install as few apps as possible. The lesser the number of apps your operating system has to work with, the lesser the chance of conflicts and battery drain issue from happening.

Also, make sure that you wipe the phone’s cache partition. The cache can sometimes get corrupted so you need to get the system create a new cache. Deleting the system cache won’t affect your personal date like photos, videos, contacts, etc so it’s perfectly safe to do. In fact, we recommend that you do it once every few months. Here are the steps how it’s done:

  • Turn off your Samsung Galaxy Note 5 completely.
  • Press and hold the Volume Up and the Home buttons first, and then press and hold the Power key.
  • Keep the three buttons pressed and when ‘Samsung Galaxy Note5’ shows, release the Power key but continue holding the other two.
  • Once the Android logo shows, release both the Volume Up and Home buttons.
  • The notice ‘Installing system update’ will show on the screen for 30 to 60 seconds before the Android system recovery screen is shown with its options.
  • Use the Volume Down key to highlight the option ‘wipe cache partition’ and press the Power key to select it.
  • When the process is complete, use the Volume Down key to highlight the option ‘Reboot system now’ and hit the Power key to restart the phone.
  • The reboot may take a little longer to complete but don’t worry and wait for the device to become active.

Among the issues that may be fixed by this procedure are…

  • Phone got stuck in the logo during boot up
  • Device entered the boot loop or can’t boot up successfully
  • Phone randomly reboots after an update
  • Device can’t get out of Safe Mode
  • Phone always freezes, lags, or becomes unresponsive from time to time

Problem #4: Galaxy Note 5 won’t turn on

My phone has had the issue that seems pretty common. The lock screen is unresponsive then the phone freezes up and then restarts.  It was been more and more frequent and then last night it went spastic, started restarting over and over again. 

When I woke up this morning, the screen was once again unresponsive, there was a LED notification flashing but nothing else. I let it sit for a few minutes and then pop it back in and power up the phone. Except as of almost 2 hours ago now, it will not power on.

When i put it on charger no battery charging light comes on. I am at a loss as to what to do at this point.  Can you help me? — Josh

Solution:  Hi Josh. The first thing you want to do is to try another charger, or connect the phone to a computer. This will help you determine if there’s a problem with the current charger or USB cord. Make sure to leave the phone charged for at least 30 minutes.

The next best thing to do is to check if you can restart the phone in another boot mode. We suggest that you try recovery mode first as doing so can give you options to either perform a factory reset or delete the system cache. Here’s how:

  • Press and hold the Volume Up and the Home buttons first, and then press and hold the Power key.
  • Keep the three buttons pressed and when ‘Samsung Galaxy Note5’ shows, release the Power key but continue holding the other two.
  • Once the Android logo shows, release both the Volume Up and Home buttons.
  • The notice ‘Installing system update’ will show on the screen for 30 to 60 seconds before the Android system recovery screen is shown with its options.

You can also try to boot in Download mode (by pressing Volume Down, Home, and Power buttons), or restart the phone in safe mode. For reference, here are the steps to boot safe mode:

  • Turn off the phone completely.
  • Press and hold the Power key.
  • Once ‘Samsung Galaxy Note5’ shows, release the Power key and immediately press and hold the Volume Down button.
  • The phone will restart but keep the Volume Down button pressed.
  • Once the phone has finished restarting, ‘Safe mode’ will be display in the lower-left corner of the screen.
  • You may now release the Volume Down button.

If nothing seems to work, have the phone checked for possible hardware problems.

Problem #5: Galaxy Note 5 overheating issue

My Samsung suddenly went off and came on after a while on its own and started showing this animation like it wanted a reboot. This lasted for over six hours without any change on the screen. After some time, it came on but I noticed that the phone was unusually hot (very hot) and ever since then it’s remained that way — very hot.

Now it goes off and comes on on its own and sometimes refuses to come on. I have done a factory reset still same problem. Please can you offer any assistance? Thanks. — Chuks

Solution: Hi Chuks. Overheating is almost always a manifestation of a hardware issue. To see if our hunch is right, make sure that you do a factory reset first. Observe how the phone works after a factory reset (without installing any apps) for at least 24 hours. If overheating remains even after a factory reset, that’s a confimation that the phone suffers from a hardware issue. Make sure to have it checked by Samsung.

Problem #6: Galaxy Note 5 audio not working properly

I have a big problem with my Samsung Galaxy Note 5. I was listening to songs through my phone on my external Microlab speaker. For some reason i unplugged the audio jack and plugged it again. it was playing fine but after plugging again i did not hear any sound. Then carefully I heard the speaker is making very very low sound. I almost needed to put the speakers in my ear to hear sound. After that i unplugged the jack and tried playing songs or any music or video through my phone speaker. But it’s all the same thing. Very little sound is coming out of my mobile speaker too at full volume. Tried headphone — it’s the same. In headphone i can hear distorted sound. Very very low. when i make a call there is no sound on my earpiece and if i talk the other person can’t hear me. What could be the problem?

I tried rebooting many times. Tried factory reset and all other things i could find on forums. Nothing seem to work. i don’t think it’s a speaker IC issue as it makes very very low sound. And moreover, i can’t hear through earpiece or headphone on calls which i guess isn’t related to the speaker IC? this is really weird. Anyone got any help for me? — Vincent

Solution: Hi Vincent. If a factory reset did not change anything, that’s a clear indication that there must be a hardware problem behind this trouble. It can be anything from a bad speaker IC, malfunctioning headphone jack, to other audio-related components. A physical check of your phone is needed to know the exact reason for the audio failure on your device. If it’s still covered by warranty, make sure that you send it to Samsung. Otherwise, call your wireless carrier for a warranty repair or replacement.
