Galaxy Note 4 Abnormal Battery Drain After Lollipop Update

Problem: I bought my Samsung Galaxy Note 4 about two months ago and it’s my first experience with Android. I love the new ecosystem and interface and all other features I haven’t experienced with Apple’s iPhone. So far, so good…until after I installed the recently rolled out Android Lollipop update. Immediately after the update, I noticed the battery doesn’t last as long as before. For example, I used my phone for Facebook and it was only about 15 minutes. When I check the battery percentage, it dropped from 87% to 81%. Before, an hour of use will only use up 2% to 3% of battery with mobile data on. So, with my Note 4 running lollipop, it won’t last a day of use unlike before. Can you help me figure out the problem is? Thank you for all the help! — Jerome

Troubleshooting: This problem is common not only to Galaxy Note 4 but to other Android devices and it often occurs after a major update. The most common cause is the corrupt data used by the new system that is why the problem won’t occur if the user boots the phone in safe mode. There, however, some cases wherein the problem wasn’t caused by corrupt app data but rather by corrupt caches used by system apps and services. But since we don’t know for sure what’s causing the issue, let’s take the safest route in troubleshooting it. The first thing I want you to do is boot the phone in safe mode and observe:

  1. Turn off the phone completely.
  2. Press and hold the Power key and the Volume Down key.
  3. When the phone starts to boot, release the Power key but continue holding the Vol Down key until the phone finished restarting.
  4. Safe mode will be displayed at the lower left corner; you may release the Volume Down key now.

When the phone is in safe mode, all third-party apps and services are temporarily disabled. So, if some of them were causing the problem, the phone should not drain it’s battery as fast as when it’s booted normally. In this case, clearing the cache and data of the third-party apps as well as updating all those that have available updates will fix the problem. However, if the problem remained even if the phone is in safe mode, wiping the cache partition will do the trick.

  1. Turn off the Galaxy Note 4 completely.
  2. Press and hold the Volume Up and the Home keys together, then press and hold the Power key.
  3. When the Note 4 vibrates, release both the Home and Power keys but continue holding the Volume Up key.
  4. When the Android System Recovery shows on the screen, release the Vol Up key.
  5. Using the Volume Down key, highlight the option ‘wipe cache partition’ and press the Power key to select it.
  6. When the wiping of the cache partition is finished, highlight ‘Reboot system now’ and hit the power key.

WiFi Drops, Disconnects Intermittently After Lollipop

Problem: I update my Galaxy Note 4 to lollipop about a couple of days ago and since around that time I can’t use my WiFi as well as I could because it often drops or disconnects after a minute or two. The phone is pretty new and before the update, it was working great that I haven’t noticed any problem. It was only after the update that I encountered a few issues that I was able to resolve except this WiFi thing. Not really a techie person so to be honest, I’m afraid I might mess up the settings if I continue to fix this problem without guidance from people who know what they’re doing. So, I really need your help guys. Please help me fix this problem. Thank you so much! — Jamieson

Troubleshooting: When it comes to WiFi issues, there are a lot of factors we need to consider and the first of them are your network equipment (i.e. modem, routers, etc.); make sure these equipment are working properly. If you have a laptop or other IP-capable devices, try to connect them to your network and see if they can browse the internet. If they can, then it’s not network-related. Otherwise, you need to troubleshoot your network by simply rebooting the equipment to refresh them. Or, you may call your service provider to get it sorted out.

But let’s assume your WiFi network is completely fine, the first thing you need to do is “Forget” the network from your device’s Settings menu. After doing this, let your device detect and re-connect to the same network. This will refresh everything and for minor WiFi issues, this procedure is very effective.

If the problem remained after doing the aforementioned procedures, then check if Power Saving Mode is enabled. There were a lot of reports from users suggesting the feature is interfering with the phone’s normal connectivity functions. You may disable the Power Saving Mode feature or just some restrictions that have something to do with wireless connectivity.

After all these and the issue persisted, then it’s time you backed up all your important data and perform a full hard reset of your device as the problem may be caused by the system itself. Here’s how you do it:

  1. Turn off the Galaxy Note 4 completely.
  2. Press and hold the Volume Up and the Home keys together, then press and hold the Power key.
  3. When the Note 4 vibrates, release both the Home and Power keys but continue holding the Volume Up key.
  4. When the Android System Recovery shows on the screen, release the Vol Up key.
  5. Using the Volume Down key, highlight ‘wipe data / factory reset’ and press the Power key to select it.
  6. Now highlight ‘Yes — delete all user data’ using the Vol Down key and press the Power key to begin the reset.
  7. When the master reset is complete, highlight ‘Reboot system now’ and hit the Power key.
  8. The Note 4 will restart but it will be longer than usual. When it reaches the Home screen, then begin your setup.

Galaxy Note 4 Cannot Install Android 5 Lollipop Update

Problem: Hi droid guys! I own a Samsung Galaxy Note 4 and about 4 days ago, I received a notification that there’s an available update. I waited a couple of days to finally deciding to download it but when I did, the phone refused to download it. I don’t know why it can’t download the update but if there’s something you can tell me to fix this problem, I will greatly appreciate it. Thank you!

Problem 2: Hello! I already attempted several times to update my Galaxy Note 4 to the recent lollipop firmware but it seems stuck somewhere. One time, the download was successful but the installation failed. There was also another time when it was stuck in the download process. Again, I already attempted several times to no avail. I really can’t figure out what the issue is, so please help me. — Barry

Problem 3: I tried installing the lollipop update to my Note 4 today but it didn’t push through. The phone is still powered on but there’s no activity for so long now. I don’t know what to do. Help me please.

Question: How come I haven’t received a notification about the lollipop update for the Note 4? My wife has the same phone she already received the notification and installed the update.

Troubleshooting: Updates are rolled out in batches, so if your wife or friend received the notification about the update, just wait until you get one. Rest assured your device will be updated soon.

Now, for Note 4s that couldn’t complete the lollipop download/installation, there are some things you need to check to make sure your phone is lollipop-ready.

  1. Make sure you are connected to a fast and stable WiFi network. Unstable WiFi connection may disrupt the download process or may corrupt some data that will consequently mess up with the installation.
  2. Your phone must have, at least, 3GB space left in its internal memory. Yes, the new lollipop firmware need that much space to be installed and run on your phone.
  3. Allow 30 to 60 minutes to download and install the new update. If the phone seems to have no activity, let it be. Remember, removing the battery during OS update may cause more serious issues to your phone.
  4. Your phone will automatically reboot after OS installation and this time, it will take more time to boot up as the new system creates new caches and data for apps and services. Don’t panic if it seems stuck during boot up, just wait until it reaches the Home screen.
  5. Apps may also take time to load for the first time after the lollipop update as they will be optimized for the new system.

I hope this helps.

Galaxy Note 4 Stuck During Boot Up After Lollipop Update

Problem: Hi! Yesterday my Samsung Galaxy Note 4 has been updated to Android 5 Lollipop update. The download and installation was smooth and fast but when the time for the phone to reboot after the installation, it got stuck during boot up. I was thinking maybe it only needed time to boot up for the first time after the new system was installed so I left it for more than an hour considering the number of apps I installed. I actually left the house to run some errands but when I came home, the phone was still on the same screen as when I left it. So, I removed the battery and tried rebooting it, still the same. So now, I’m confused why this is happening and at the same time very annoyed because the new update messed up everything for me. I need your expertise on this. Thank you. — Leanne

Related Problem: After I downloaded lollipop to my Note 4, the phone freezes when it starts up and won’t continue to the Home screen. My brother said to remove the SIM card and reboot but it’s still the same. My neighbor also told me to remove the battery and press the Power button for 30 seconds and then try to reboot but the problem is still the same. Don’t know what to do at this point. Help me.

Troubleshooting: Hi Leanne! I will, of course, assume that the download and installation was successful. More often, the phone gets stuck on the boot up screen after the update when some caches were corrupted during the process. Clearing all them will fix the problem, so that’s all you need to do to continue using your phone. Just follow these steps and you’ll be fine:

  1. Turn off the Galaxy Note 4 completely.
  2. Press and hold the Volume Up and the Home keys together, then press and hold the Power key.
  3. When the Note 4 vibrates, release both the Home and Power keys but continue holding the Volume Up key.
  4. When the Android System Recovery shows on the screen, release the Vol Up key.
  5. Using the Volume Down key, highlight the option ‘wipe cache partition’ and press the Power key to select it.
  6. When the wiping of the cache partition is finished, highlight ‘Reboot system now’ and hit the power key.

Some Of The Apps Won’t Open After Lollipop Update

Problem: Hi Harold. I’ve been following your blog ever since you posted the first part of your Galaxy Note 4 troubleshooting series. I enjoyed reading the first few posts but I haven’t had issues with my phone until I downloaded the recent lollipop update. I successfully installed the new firmware and the process was actually smooth. The phone’s performance improved and I love the new interface and additional features. However, some of the apps I installed won’t work anymore after the update. I know the problem is update-related as I was still able to use these apps before I updated my phone. I rebooted many times already because I’m afraid to change the settings in my phone thinking I might cause more trouble than good. I need your advice on this. How can I make these apps work again? — Lilibeth

Troubleshooting: More often than not, if an app won’t work after a major update, then it’s a compatibility issue. Meaning, the app needs to be updated so it would work or run smoothly on the new system. Apps developed by small-time (individual) developers are often the ones to have problems like this. Modifying a running app will also take time and only big-time developers can afford to spend so much time tweaking their apps and make them compatible with the new firmware, in this case, it’s Android 5 Lollipop.

That said, the first thing you need to do is check via Google Play Store to see if there available updates for apps that won’t open after the recent update. If there are, then update the apps at once to fix the problem. Otherwise, the best thing to do is clear both the cache and data to see if that would make a difference. Also, uninstalling the app and downloading a fresh copy from the Play Store may fix the issue. But if all else failed, it’s time you contacted the developer of the app and report the problem. There’s nothing much we can do if it’s a compatibility problem than wait until the developer releases a patch to fix the issue or a new update to make the app run on a new system.

Galaxy Note 4 Overheats After Lollipop Update

Problem: I noticed that after I updated my Note 4 to lollipop, it began to develop heat like it never did before. It’s not normal because when I hold the phone, the heat will make my hand feel uncomfortable. Since I bought the phone 3 months ago, I have always been observing its performance and behavior and immediately after the update, the performance deteriorated and then there’s excessive heating. Not really sure what caused these issues but if you have something you can suggest I do to fix them, I would greatly appreciate your effort. Thank you and please continue with what you’re doing. You are helping millions of Android users around the globe. — Ben

Troubleshooting: There are a lot of factors that may contribute to the development of heat in a device and considering Note 4 is a powerful smartphone, it develops heat faster than phones with lower specs. But then, of course, the heat it develops must be within the threshold because too much heat can damage some of its components inside not to mention the discomfort it creates for its user.

Since the problem started immediately after the lollipop update, we can narrow the problem down to corrupt data or caches and more often, third-party apps are among the common culprits. That said, it would be wise to boot the phone in safe mode first and then observe its performance and how much heat it can develop when all third-party apps are temporarily disabled.

  1. Turn off the phone completely.
  2. Press and hold the Power key and the Volume Down key.
  3. When the phone starts to boot, release the Power key but continue holding the Vol Down key until the phone finished restarting.
  4. Safe mode will be displayed at the lower left corner; you may release the Volume Down key now.

If the phone still develops too much heat even in safe mode, there’s no other option but to perform full hard reset so that all corrupt data will be wiped out. Otherwise, you need to find those apps that are causing the problem; begin with apps that need to be updated.

Full Hard Reset

  1. Turn off the Galaxy Note 4 completely.
  2. Press and hold the Volume Up and the Home keys together, then press and hold the Power key.
  3. When the Note 4 vibrates, release both the Home and Power keys but continue holding the Volume Up key.
  4. When the Android System Recovery shows on the screen, release the Vol Up key.
  5. Using the Volume Down key, highlight ‘wipe data / factory reset’ and press the Power key to select it.
  6. Now highlight ‘Yes — delete all user data’ using the Vol Down key and press the Power key to begin the reset.
  7. When the master reset is complete, highlight ‘Reboot system now’ and hit the Power key.
  8. The Note 4 will restart but it will be longer than usual. When it reaches the Home screen, then begin your setup.

Galaxy Note 4 Keeps Connecting To Mobile Data After Lollipop

Problem: I am currently experiencing a very weird problem with my new Note 4 and it started after I updated the phone about 3 days ago. The problem is, it keeps on reconnecting to mobile data and disconnects from my WiFi network and between those sessions, internet connectivity is cut off. In short, I cannot get a decent internet connection even if my WiFi network is fast and stable because the phone thinks I wanted to use mobile data. I am 59 years old and I’m not really savvy when it comes to this thing. I’m afraid I might change something that will break my phone. By the way, the phone was a gift by my daughter so I really don’t have a choice but to accept and use it. I have worked with a tech company so I have a little understanding how internet works but when it comes to troubleshooting some problems, I’m not into that. Can you help me, please? — Josie

Troubleshooting: Hi Josie. This problem is common to Galaxy devices that recently received lollipop update. The Note 4 has a feature that will allow it to connect to a network that has better signal. While it is a useful feature, more often, it becomes very annoying as it makes the phone dumber. That said, it would be better if you turn the feature off to fix this problem. Or, if you don’t use mobile data, turn it off so that the phone will be forced to connect to WiFi even if the signal reception isn’t that good. To disable Smart Network Switch feature, follow these steps:

  1. Swipe down from the top of the screen with one finger.
  2. Tap the Settings icon.
  3. Tap Wi-Fi.
  4. Tap the checkbox next to Smart Network Switch to uncheck it.
  5. Tap OK.

Galaxy Note 4 LED Indicator Not Working After Lollipop

Problem: Hi guys! First of all, thank you for making yourselves available for us users. You’re more helpful than other websites in this niche.

I have a problem with my Galaxy Note 4 but before that, one of the features I love most about this phone is the fact that it has LED indicator that notifies me whenever something has arrived or if the battery is low and so on. After the lollipop update, the indicator doesn’t work anymore and as much as I want to troubleshoot, I really just want to know if Samsung intentionally removed the feature.

Of course, I will be very happy if you can help me turn it back on because, at night, I always rely on it to tell me if I have messages or missed calls. More power to your website. — Rose

Troubleshooting: Hi Rose! Removing the feature would be one of the most absurd decisions Samsung could ever make considering majority of its devices have LED indicators. It would be a total waste of resources having a component that won’t function. So, the answer to your question is no. Samsung didn’t remove the feature.

However, Android 5 Lollipop can now disable all notifications if the phone is set to Silent Mode or muted. If, the phone wasn’t muted but the LED indicator still won’t notify you, then make sure the phone is set to notify you for your desired alert types. Go to Settings > Display > LED indicator > check desired alert types. At this point, the problem should have been solved already. Otherwise, you need to further check on the General Priority Notification settings by going to Settings > Sounds and notifications > Interruptions > set priority interruption for Events and reminders, Phone calls or Messages.

How To Change Font Style on Note 4

Question: Hi. I recently purchased a brand new Galaxy Note 4 and it is my first Android phone. I’m still learning how to use it to my own advantage and there’s one thing I can’t figure out; how can I change the font style? By the way, I already updated it to the latest firmware and I’ve seen from a friend that the font style of his Note 4 was different from the default. Do I have to root the phone to have a new font style? Or, is there a setting for it? Thanks! — Mia

Answer: Hi Mia! Welcome to the Android bandwagon! Note 4 is a good phone for starters. To answer your question about whether you need to root your phone to change the font style, no, you don’t have to. There’s a setting for that, although, I understand why new users can’t easily find it. Go to Settings > Display > Font > Font style. Now choose among the available font styles and hit the Download button. That’s pretty much it!

How Can I Delete All Personal Information on Note 4
