Problem #1: Galaxy Note 4 slow internet and fast battery drain issues after an update

Dear friends. After the update from 5.0.1 to 5.1.1 the WCDMA internet data is very, very, very slow and battery drain very fast. I made soft reset, wipe cache, factory reset. Same problem. With 5.0.1 work perfectly. I’m from Romania, carrier is Telekom.

I tried to downgrade to 5.0.1 with Odin and SamMobile stock rom but Odin cannot write to NAND.I follow all yours advices on:

http://thedroidguy.com/2015/11/samsung-galaxy-note-4-problem-after-software-update-1051650 but still no success. Very slow internet and battery drain. APN is correct like was on 5.0.1, no changes. Please help me. Best regards. — Mihai

Solution: Hi Mihai. Update problems are usually resolved by doing the basic software troubleshooting and solutions we provide including everything that you have done. Since nothing changes and issues appear to be coming from your carrier’s update, make sure to let them know about especially the one that concerns slow internet connection. There’s nothing more that you can do on your end to fix them.

Problem #2: Galaxy Note 4 won’t install Android update

Note 4 with similar issues. i can download the most recent update 150.5MB but it won’t install. I have 14Gbs  available memory and already have to hard reset my phone on a regular basis maybe once a week due to crashes. Not a big deal there as i have my phone and all contents backed up to too many clouds, PC, laptop etc… as it is.

Kies being called Smart Switch now no matter neither has worked when they were technically separate entities. No, i do not have a custom ROM, nor is it SIM unlocked as I’m more than familiar on how to mod my devices but have my Note 3 for that.

Whew… All that being weened out at this point if an option exists how, where, or does a complete file replacement albeit gutting the OS and starting fresh with a  new factory image?

I have been on chat with Samsung and all they’ve offered is warranty repair and “Safe mode” for a few hours as to “Repair itself”… If its a dead stick i understand but if possible i like fixing these issues myself and at times with a guiding hand with some tricks i don’t know. Thanks! — Mark

Solution: Hi Mark. Try this trick: charge your Note 4 and unmount the external SD card. After that, try to restart the phone normally then insert the SD card again. Keep in mind that this is only a workaround and may not work on all devices. This procedure can also potentially damage your SD card. If you want to take the risk, make sure that your files in the SD card are all saved to a different device before proceeding. Otherwise, simply go ahead with Samsung’s suggestion for a warranty repair. There’s nothing more that you can do on your end to fix it.

Problem #3: Internet and fast battery drain issues after updating Galaxy Note 4

Ever since the Lollipop 5.0.1 update came out, my Note 4 hasn’t been working properly. Battery drainage is one issue, but nothing works on my 4G network. Before, the apps would give me notifications and work fine whether connected to 4G or Wi-Fi, but after the update, all my apps are unresponsive. They don’t load properly or send notifications while I’m away from home.

But as soon as I connect to WiFi, my phone gets bombarded by notifications and will sometimes freeze and needs to be rebooted. None of my apps are Restricted, I’ve removed, deleted and reinstalled, but it’s the same issue. Is there a fix or will this be something I have to deal with?

Thank you for your time. — Jorge

Solution: Hi Jorge. It’s usually recommended to delete the system cache and do a factory reset after a system update, especially if problems start to manifest. Here are the steps to do them.

How to wipe the Note 4 cache partition

  • 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 Vol Up key.
  • Using the Volume Down key, highlight the option ‘wipe cache partition’ and press the Power key to select it.
  • When the wiping of the cache partition is finished, highlight ‘Reboot system now’ and hit the power key.

How to do a Note 4 factory reset

  • 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 Vol Up key.
  • Using the Volume Down key, highlight ‘wipe data / factory reset’ and press the Power key to select it.
  • Now highlight ‘Yes — delete all user data’ using the Vol Down key and press the Power key to begin the reset.
  • When the master reset is complete, highlight ‘Reboot system now’ and hit the Power key.
  • The Note 4 will restart but it will be longer than usual. When it reaches the Home screen, then begin your setup.

Both procedures are known to be effective solutions for firmware- or cache-related issues after a major update. If nothing changes, that means that the cause of the issue may lie somewhere else. Make sure that all your installed apps are compatible or optimized to work with the current OS. Some developers may no longer update their apps as new Android versions are released. This can cause problems that can show in many forms including slow performance, freezing, crashing, or preventing basic functions to function properly. Try to install apps individually and make sure to observe the phone’s behavior before installing another one to isolate the possible culprit.

Problem #4: No 4G signal on Straight Talk Galaxy Note 4

HELP!..I have a AT&T Note 4. I bought it unlocked and use Straight Talk plan AT&T service. Everything has worked fine — no complaints. ISSUE- I went to Europe, KIEV, for two weeks. I bought a SMS Ksatr service and installed SIM card. everything worked fine again. I come home put in my Straight Talk SIM and…no 4G. The phone doesn’t show my service any longer. Only way to get internet is if Im by Wi-Fi which works.

Here’s the strange part. I can make and receive phone calls. But it does not show my network any longer and no 4G. Upper left says HOME.

I know the tech manually ran some numbers to set my service up in Kiev. Did she change some setting that now prevents my service.

Once phone is unlocked is it not always unlocked?  I’m sure it’s just a matter of resetting some setting but have no clue.

CAN YOU HELP ME??  Thanks. — Lee

Solution: Hi Lee. The answer depends on what changes were made by the Ksatr staff on your phone. If they merely modified or added the APN settings as well as other network settings like selecting a different network mode. The first thing that you can do is to ensure that the phone’s network mode says 4G. You can do that by going under Settings>Mobile data>Network mode. If the phone already says 4G under network mode but doesn’t pick the right signal, make sure to call Straight Talk technical support and ask for direct assistance from them.

Problem #5: Galaxy Note 4 slow mobile connection speed

Hello Sir. Please I’ve got a problem making my life­ a living hell. I am using a Samsung Galaxy Note 4, and ­it’s 2G connectivity is very horrible. When it drops from 3G to G, it gets very­ slow and very very unstable. Most times­ I need to turn airplane mode on and off­, to reset the network bars, when on “G”­ to be able to open Google on Opera Mini­.

But the speed is very normal on H+ and 3­G.

Because I am in Cameroon, a country in C­entral Africa, my operator’s signal in i­ndoors (my apartment) is only on “G”. I ­need to step out to access H+. And when ­I get back indoors, before it goes back ­to G, the network bars go off for a shor­t while, as if it is restarting and come­s back on with G.

And it takes relatively long to move to ­3G from G.

Before now, I had an S3 and I could at le­ast browse, eventhough a little slow. Now with­ my Note 4, it is sooooo slow and very u­nstable as i explained above.

I also noticed that when I create a grou­p for another to join and share files wi­th me on Flashshare (app, which creates ­a Hotspot to share files), sending or receiving is extremely slow (32kb/s). But w­hen another creates and I join, the spee­d is very fast (7000kb/s).

I don’t know if it’s the software (custo­m rom?) or something.

Please help me. It is making my life a l­iving hell. — M

Solution: Hi M. The first issue regarding connection speed on your phone is not obviously not your fault, nor a device problem. “G” signal means that your device is only receiving the slowest Internet data transfer speed. Given how websites are designed today, G signal speed is not even fit enough to load a site page fully. “G” stands for General Packet Radio Service (GPRS) which is the slowest and the oldest mobile technology in the planet. It’s bandwidth is usable for calls and text but it’s never meant to handle demanding requests for internet access. GPRS data transfer speed is rated between 56 and 114 kbit/second, which is barely enough to even open a decent website page. If you want to browse the web inside your apartment, you must find a way to boost your carrier’s signal so enhanced HSPA (H+ signal) reaches your device. In the U.S., subscribers can ask their wireless carriers for a signal booster to be installed to improve signal reception. Try to talk to your carrier about your options regarding the matter.

The second issue regarding the slow transfer speed when using the Flashshare may be phone related. We don’t know how this app works exactly but generally, the transfer speed also depends on the device that creates the hotspot. The Galaxy Note 4 has a pretty fast transfer speed when moving files via its wireless radio so we don’t know if you have an issue with the app as well. Try to talk to the app developer and ask them for direct assistance.

Problem #6: Galaxy Note 4 won’t connect to work Wi-Fi

Hi All. Greetings!

From 2 days I have problem in connecting my mobile to Wi-Fi in my office. Earlier it was working well. Others in my office can access the Wi-Fi even now except me. And I am able to access Wi-Fi at home or in other offices.

In short only my mobile is not getting connected only to my office Wi-Fi connection.

I have restarted my mobile, clicked forgot password and again logged in, I closed mobile with forgot password and logged in again after restarting mobile, all of these is not able to fix the problem.

Can you please suggest?

Regards. — Alex

Solution: Hi Alex. Please talk to the Wi-Fi administrator so they can check if your device has been filtered out of the system. We can’t see any other reason why the device won’t connect to the internet other than this. Some type of restriction or limitation may have been put in place to limit internet access for your device.
