Galaxy Note 4 fails to power on after installing an app, other power-related issues

Power-related problems on #SamsungGalaxyNote4 by installation of an app is rare but that’s what one of our fellow Android user experienced. No same apps react almost the same way in different devices. The dynamics of many apps and firmware version vary per device so there is no surefire way to anticipate all problems. This is one of the biggest challenges Android developers face when designing and debugging their apps. It is no wonder that we sometimes get unusual problems like the one below. We hope that the standard troubleshooting and solutions provided in this article are helpful.

Problem #1: Samsung Galaxy Note 4 does not turn on after installing Holo Launcher app

I have been using my Note 4 for close to a year now. I installed CM Security with the charge boosting feature enabled, I have used the phone with this configuration for several months without any issue at all. CM Security is a very good app.

About three days ago, I saw Holo Launcher advertised on my Facebook page. I downloaded the launcher from Google Play Store and installed it. I configured it the way I wanted but did not see any power or charge boosting feature with it.

I used the phone until I got a low power alert from CM Security power booster and it asked and I accepted that it closes some power hogging  apps, the power went down to 15% I then put the phone on charge. When I plugged the phone to power, I saw a power screen saver different from that of CM Security, it started restarting the programs that were shut down due to power insufficiency, during this activity, restarting apps, the screen went off blank and I was not able to turn it on again.  I have tried all troubleshooting tips and trick, including the one on your site, but I cannot bring my phone back to life any more. It appears to me that Holo Launcher or the combination of Holo launcher and CM Security could be very destructive. Any help you could offer will be highly appreciated.  — Ishaque

Solution: Hi Ishaque. We’ve heard of Holo Launcher app but are not familiar with its code or how it interacts with other similar apps. Installing multiple launchers on an Android phone is common and we don’t know of any serious problems like the one you have to happen. Something must have triggered the quick battery drain issue which eventually resulted to total boot failure. If installing Holo Launcher is the only difference done on your phone prior to the problem, that might very well be the cause of trouble here.

Because you did not specify what troubleshooting suggestions you have tried so far, let us give all the things that you can try again here for your benefit as well as for other readers having a similar problem.

Boot the phone in recovery mode

Recovery mode is a special environment for your device designed to allow users to do repair or install operating system updates if the normal methods of doing such maintenance tasks are not available. In recovery mode, you also have the option to reset the phone to its factory defaults or delete the system cache. You can boot your Note 4 in recovery mode by doing these steps:

  • Turn off the Galaxy Note 4 completely.
  • Press and hold the Volume Up and the Home keys together, then press and hold the Power key.
  • When the Note 4 vibrates, release both the Home and Power keys but continue holding the Volume Up key.
  • When the Android System Recovery shows on the screen, release the Volume Up key.

Once you are in recovery mode, you can navigate to available options using Volume Up and Down buttons. To select an option, simply press the Power button.

If you can successfully boot your Note 4 in recovery mode, select the wipe cache partition option to delete the system cache. This ensures that your device uses a clean set of cache. Outdated or corrupted system cache sometimes lead to problems like apps freezing, crashing, or failing to work normally.

If wiping the cache won’t make any difference, please proceed to restoring the phone’s defaults via factory reset. This will wipe everything off the phone’s internal memory unit so you will lose whatever files stored there. Only consider wiping the phone totally if you have already tried doing everything. Files, photos, videos, etc stored in the cloud can be recovered later.

Boot the phone in download mode

Download mode is another special mode in your device that provides an option to flash (install) a new ROM or a stock ROM or firmware using a program like Odin. If you rooted your phone or customized the ROM before you installed Holo Launcher, consider unrooting your device by flashing to stock firmware. Please use Google for instructions on how to flash your phone to stock ROM or firmware. The stock ROM on your phone may be specific to your carrier so make sure to check this before you proceed. That means that if you get the device from T-Mobile, the stock firmware should be from them and not from other carriers like AT&T, Sprint, Verizon, or any other carrier.

Make sure to download the correct file for you Note 4.

Problem #2: Samsung Galaxy Note 4 does not charge and showing Power Sharing mode message

I have been having issues with my phone doing 1 of 2 things.  1) not charging at all. I have replaced the battery and gotten a new Samsung charger. Taking the battery out and replacing with full one is the only thing that works sometimes. After restarting or taking battery completely out a couple times it will start to charge.  Or 2) the phone say that it is  in “power sharing mode”  and it will completely drain my battery.  I did find this option in my Samsung apps area but I only have the option to pause it, not disable it. So it will drain it until My battery is down to 20%. I’m going to try a factory rest today and see if that helps.  Any advice, or solutions for this problem? — Jackie

Solution: Hi Jackie. There’s only so much a user can do when it comes to charging problems and we think you have already tried almost all of them. If after using another battery and charger doesn’t work, the problem is clearly on the phone. This means that’s it’s either a hardware malfunction or a firmware issue. Please do a factory reset and see if it will make any difference. Doing so may also resolve the second problem.

And speaking about power sharing mode, this is actually related to a Samsung-developed app named Power Sharing. While created by Samsung, it is not pre-installed so you if have this app, you can simply uninstall it.

Power Sharing app is designed to allow users to charge other devices by sharing your Note 4’s remaining battery power. Using a special Power Sharing cable, you can transfer power to other devices easily like a regular power bank. This app only gives you two options when enabled–Start and Pause. If you don’t plan on sharing power to your other devices, please remove this app from your phone. Here’s how:

From any Home screen, tap the Menu key.

  • Tap Settings.
  • Tap the More tab.
  • Tap Application manager.
  • Swipe left or right to go to the All tab.
  • Scroll to and tap Power Sharing.
  • Tap Uninstall.

Problem #3: Galaxy Note 4 restarting randomly after updating to Lollipop 5.1.1

Since receiving the new 5.1.1 update, It dies at 10 percent with no warning beep before doing so. It used to do the 15 percent and the 5 percent battery warning beeps. So after the phone dies, it then restarts itself automatically. When loaded up it shows 0 percent on the notification bar and then dies again for good until charge. Any ideas what could be causing this or any other similar reports? — Jeffery

Solution: Hi Jeffery. If problems started happening after an update, make sure that you clear the phone’s cache partition to delete corrupted or outdated system files left after the update. The steps are provided above.

Problem #4: Galaxy Note 4 won’t boot in download mode

Hi. I have a Samsung Galaxy Note 4 model SM-N910F.  It is running Andriod version 4.4.4 and I have very bad reception with this phone and I have been told to update the firmware. I have tried to get this phone to connect to Kies and won’t work and I have tried to put phone into download mode via Volume Down, Power and Home button. When using those buttons it takes me to Factory Mode which OS actually Chinese writing…I don’t know where to go from here to get an update done. Odin won’t read phone till in download mode. I’m willing to root it as there is no warranty…can you help me? Thanks. — Michael

Solution: HI Michael. There’s no logical explanation why your phone fails to boot in download mode but we noticed that turning off the phone, removing the battery, putting it back in, turning the phone again, and finally, attempting to boot in download mode have worked in older Samsung flagship Galaxy phones before. Please try that. If nothing works, consider doing a factory reset.
