There were considerably many owners of the Samsung Galaxy Note 3 to have complained about the device’s tendency to boot up with a blank screen. While the manufacturer, Samsung, didn’t provide an explanation as to why the issue occurs, we understand there would always be problems in the manufacturing of the device and not all units are built perfectly. There were always be units that could be considered “reject’ and it’s just a matter of who gets which.
Based on our online research, blank screen could be more than just a manufacturing flaw. There were also instances that the blank or black screen occurs due to insufficient power or due to the malfunction of some third-party apps. But basically, it’s just a matter of uncovering what the real cause of the problem really is.
This post, however, will help you determine what makes your Samsung Galaxy Note 3 go blank all of the sudden. But before anything else, here is a couple of emails from our readers telling about their experiences with the Samsung Galaxy Note 3 black screen:
“My Note 3 is just a month old and in that span of time, I already experienced at least 5 times that the screen goes blank while I’m in the middle of something. Once the screen goes black, it seems that my device would stop responding and all I gotta do is remove its battery and boot the device up again. I do this every single instance that my screen goes blank and it always resolved the problem. But I hope you could provide a permanent solution to this problem. Thanks.” – Roberto, NJ
“I am currently experiencing a bizarre problem with my Galaxy Note 3. Just today, when I boot it up, the screen remains black, although I know it is powered on because I can see the backlights turn on. I thought it was going to be like that for a few seconds but I waited 15 minutes and the screen remains black. So, I had to remove the battery from my device to turn it off completely. I tried researching online but found a few similar problems so I know it is very rare. Have you guys experienced this problem. Please shed some light because I really need your help to make this go away.” – Justin, MN
Drained battery or not enough battery to power the screen up.
Third-party app is messing up with the phone’s normal operations.
Temporary device issue.
Hardware or internal component problem.
Step 1: Plug the Charger In
It is undeniable that the Samsung Galaxy Note 3 is one of the most powerful mobile devices ever built with its quad-core processor (regardless whether it uses Qualcomm’s Snapdragon 800 SOC or Samsung’s proprietary Exynos chip) integrated with a graphics processing unit (GPU) that enhances its top of the class Super AMOLED display.
One of the reasons why the Note 3′s display remains blank even if backlights are already on is because its display needs more power than its backlights. The first thing an owner should do if ever this problem occurs is to make sure there is enough charge in the battery to power all components including the display. Therefore, it is recommended owners should plug the charger in and let the device replenish its power before attempting any other troubleshooting steps.
Step 2: Power-shock the Phone
This procedure will attempt to drain static electricity in the device’s components and to refresh its memory. While the term used sounds more “techie,” power-shocking simply follows a very simple procedure:
While the device is on, remove the back panel off and take the battery out.
Leave the phone without battery for a minute to allow it to discharge all electricity stored in its components.
Place the battery back and boot the phone up normally.
As mentioned in both emails at the beginning of this post, the owners said they need to take the battery out to turn the phone off completely and once they would boot the phone up, the problem is gone. But obviously, this is just a temporary remedy. But the purpose of this procedure is to turn the phone back on so that owners could manipulate the device again and investigate further.
Step 3: Find the Rogue App(s)
There were reports that some apps may result to having the phone freeze up to the point that it becomes unresponsive. When this happens, the screen goes blank or dark while backlights are still on.
Many of those who have experienced this problem were gamers and there are quite a lot of games that require higher resolution rendering. While the Note 3 is a very capable device when it comes to specs and graphics, the amount of data being transferred may sometimes result to a hold up.
If you are pretty sure that an app is causing the problem, you must decide whether to keep the app and experience the same problem over and over or uninstall it and find something new or an alternative.
To uninstall an app, follow this:
Go back to the Home screen, then tap the Menu key.
Tap Settings, then More tab.
Tap Application Manager.
Swipe to right once to choose All tab. (Other tabs are Downloaded and Running.)
Scroll up or down to look for the app you suspected of bringing ads to your notification bar.
Tap the Uninstall button.
Tap the OK button.
Step 4: Send the Phone for Repair
If the problem persists and you’ve done everything to resolve it, there’s no need for you to pop the phone open because you might end up voiding its warranty. Instead, bring the phone to where you bought it and have it checked by an authorized technician. If it is a hardware problem, you may be given a replacement unit or the problem will be fixed permanently.
