Galaxy S4 Cannot Get Rid Of Accuweather

Problem: I have just got my first smartphone a Sprint Samsung S4. I was playing with the accuweather app and realized I did not now how to turn it off. I was able to use the app manager to uninstall the app. It removed the app icon but not the running program. The weather is there when I turn the phone on. I did a factory reset, but the program is still running. How can I get rid of it? How should I have turned it off ie not showing any weather information. Salutations from beautiful downtown Carmichael, CA.

Solution: Apps that are pre-installed with a device are usually difficult to remove unless you root your device. In your case you have a Sprint Galaxy S4 which I’m sure comes with several bloatware. When you uninstall any of these pre-installed apps what you are actually doing is simply uninstalling the update of the app and not the app itself. This is why when you uninstalled Accuweather the app is still present in your device. The only way to get rid of any unwanted pre-installed apps in your device is to get root access however since your phone is still new then this process is going to void its warranty. If you really want to get root access then I suggest following the procedures outlined in some of the popular Android forums. Just make sure to follow the procedure for your specific model and firmware.

Galaxy S4 Unable To Switch On Wi-Fi

Problem: Hi, I purchased 2 x S4’s in December 13 via Amazon. Both worked ok with no problems, around about April my S4 started having wi-fi problems, it would not always connect to my router. I would have to put in the router id again and then it would be ok. The other phone worked perfectly on the router or at a hotspot etc. Eventually my phone would not switch on so I took it to my local phone guy who reset it. By the time I had got home it had switched off again, after taking it back to the guy again this time it worked ok. I switched the phone off whilst at a meeting and since then it I cannot get the wi-fi to switch on. All this time the other S4 has been perfect.I checked OS etc on both phones and found that my S4 was running19505XXUFNB8, the good phone was running 19505XXUFNC4 (still is). I tried to root my phone using CF autoroot and Odin to change  ro.securestorage=true  to false (a parameter in build prop) as one forum said this would cure my problem. Although I could change it I could not save it.Super SU would not Install

properly. Eventually the phone got stuck in a boot loop. Which cleared when I reinstalled   19505XXUFNB8. Since then I have installed via Odin 19505XXUFNC4 so both phones now have the same os’s hoping that this would cure the problem but it is Wi-fi is still not switching on!I f you can help or have any ideas I would be grateful, Thanks

Solution: When a phone has problems with its Wi-Fi it could be caused by a hardware (phone or router), settings issue (phone or router), or software (phone). You’ve already eliminated the possibility that it is a router problem since your other S4 works perfectly when connected to it. You’ve also eliminated any software related issues on your S4 since you were able to replace its OS but still the problem still occurs. This could already be a hardware issue with the device itself. The Wi-Fi module could have a problem which in this case must be checked at an authorized service center.

Galaxy S4 Moving App To SD

Problem: I’ve had the Samsung Galaxy S4 for a little over a year now and for the last month or two if I allow an app to move to my SD card it will no longer open. I have to uninstall and reinstall it, then make sure it is only on the device memory before I open it or else I have to repeat the process. I have a 64 GB micro SD card with about 30 GB of music on it so I’m pretty sure it’s not a card issue as all of my music plays well on DB Poweramp. Do you have any idea why this is happening?

Solution: Is your Galaxy S4 now running the latest Android KitKat update? If so then this is one of the security features in this version. Prior to this update apps were able to write data freely on an SD card but with the update this ability has been blocked. The same goes with installing apps in external storage. A lot of people are complaining that they can no longer move apps on their SD card or access the app that was already moved to the SD card after they updated their device to KitKat.

What you could do right now is just install your apps in the internal storage of your device.

Galaxy S4 Update Issue

Problem: Dear Admin, I always like to read you on Drippler so I am taking opportunity to share my problem related to my S4. Yesterday I received Software Update for my kitkat4.42 and it took an hour to get it updated and installed. while installing I received a message that ” Pulse can not be installed” and then it rebooted. Now while checking update I still find the Android version 4.42 instead it should be 4.43, So I need your guideline, your help and your valuable advice to resolve the problem,if it is so. Thanks and regards.

Solution: Ok, it looks like the update process on your S4 failed. Here’s what needs to be done. First backup all of your important data saved in the internal and external storage of your device. The next step is to do a factory reset on your device.

  • Turn the phone off
  • Press and hold VOLUME UP and HOME (middle) button
  • Press Power until the phone vibrates
  • Wait until you see the Android logo then release all buttons
  • Select Wipe data/Factory Reset with VOLUME DOWN, press Power (right hand-side)
  • Select Yes –delete all user data with Volume Down and then press Power
  • After format, press Power again to reboot Power. (select reboot system now)

Next make sure you have the latest Kies software installed in your laptop.

  • Launch the Kies program in your laptop
  • Connect your S4 to your laptop with the USB cable.
  • If this is the first time you connect your phone it will first install the necessary drivers
  • If any updates are available a pop up will appear. Click update and hit confirm once you have read the caution statements.
  • Hit the start upgrade button.

Galaxy S4 Wi-Fi Issue

Problem: If I leave the Wi-Fi turned on and let the phone sit unused for a few minutes and then try to use it, the phone locks up and then reboots a minute or two later. It only does this if the phone isn’t being used and the screen goes blank (screensaver). Then when you activate the screen to use the phone, lock city then reboot. The phone works fine as long as I’m using it, or if I turn off the Wi-Fi before allowing the phone to sit idle. I’ve tried toggling the auto network switch setting, but it doesn’t effect this. One thing I haven’t tried is to change the setting that keeps the Wi-Fi on when asleep. I’ve changed that to never, which might solve the problem, but I feel that I shouldn’t have to deal with this in the first place. I’ll let you know how the change in settings works out.

Solution: Yes you should try changing the Wi-Fi setting to on when asleep and see if it solves the issue. Another point to consider is that there may be a third-party app that is causing this. To test if this is the case you will need to boot your device in safe mode. In this state your S4 will not load any third-party app. Check and see if your phone still reboots.

To enter safe mode

  • Turn off the device.
  • Press and hold the Power/Lock key for one or two seconds to turn on the device.
  • When the logo displays, press and hold the Volume down key until the lock screen displays.
  • When the lock screen displays, Safe mode shows in the lower-left corner of the screen.

If the issue cannot be duplicated in safe mode then chances are there is an app that you have installed that is causing this. Unfortunately we won’t know which app it is unless we uninstall it. This means you will have to manually uninstall each of the apps that you have installed and check afterwards if the issue still exists. This process has to be repeated until the device works normally.

Galaxy S4 Deactivating Knox As Device Administrator

Problem: I unfortunately enabled Knox on my s4. It’s now an “active device administrator”.  I can’t change it or deactivate it or uninstall it. When I get into the screen where I can uncheck it as an active device administrator, it is “greyed out” and can’t be unselected. Knox has also locked several other applications and made it impossible to uninstall them. What can I do to deactivate Knox as an active device administrator?

Solution: Knox is one of the latest security features that Samsung is pushing to its devices. This protects the data of the device against unauthorized access unfortunately due to its strict nature some users don’t like to have it in their phones. Right now there is no way to deactivate Knox as an active device administrator. There is however a way to disable it as long as your device is rooted and you have the SuperSu app installed.

Using Terminal Emulator

  • Go to the Play store and download the app called ‘Terminal Emulator’ and install
  • Once installed, launch the app and grant it the root permission when asked.
  • You’ll be given a command prompt in which you’ll have to type the following command “su pm disable com.sec.knox.seandroid
  • Knox is now disabled

Using Titanium Backup

  • Go to the Play store and download the app called ‘Titanium Backup’ and install
  • Once installed, launch the app and freeze the following applications from running KNOX, KNOX Store, KLMS Agent, Knox Notification Manager, com.sec.enterprise.knox.attestation, com.sec.knox.eventsmanager

Galaxy S4 Not Receiving Emails After Update

Problem: After the latest update. Not receiving any emails anymore. I even downloaded an email app and for awhile it worked. But now not getting new emails.

Solution: Try pulling down the notification bar on top of your device and see if the sync is activated. A lot of users of the S4 who updated their devices discovered that sync got disabled after the update process. If it is disabled then just tap on it to enable it and you will soon be receiving your emails.

If sync is enabled and you are not getting emails then you might want to delete your email account from your device then re-enter it again. Before deleting your account make sure to restart your phone first.

Galaxy S4 Sound Issue During Mirroring

Problem: Hi team , The moment I switch on to screen mirroring options on my cell phone ie Samsung galaxy s4 , the audio stops working. Not even my cell or  tv (Samsung smart tv 2013 model )sound controls helping to get audio. Is this a software issue with my phone or screen mirroring has some issues in s4. Waiting for your response.

Solution: Screen mirroring should work fine on the S4. First check on the audio settings and see if the problem lies here. If not then you could try rebooting your S4 and your TV before doing activating screen mirroring and see if the issue gets resolved.

Galaxy S4 Gets Very Hot

Problem: Have an un-rooted at&t Galaxy s4 that gets very hot to touch at times and end up removing battery let it cool down and then restart it.  Have not been able to pinpoint a particular app causing it. Have not been using GPS on it either to cause it. The phone is running the latest AT&T rom for version 4.4.2. The behaviour is very random with no specific time or place dictating it. Have 2 other at&t S4s with a lot more apps on it running same rom purchased at exact same time,  but those are not exhibiting this behaviour. Any insight will be appreciated. Thanks

Solution: A phone that is hot even when not in use is a sign that there is an activity going on. This could be caused by a service that is turned on (Wi-Fi, Mobile Data, GPS), an app that is running, or even a malware. What you should do first is to start your device in safe mode. This disables any third party app.

  • Turn off the device.
  • Press and hold the Power/Lock key for one or two seconds to turn on the device.
  • When the logo displays, press and hold the Volume down key until the lock screen displays.
  • When the lock screen displays, Safe mode shows in the lower-left corner of the screen

Observe your device and see if it gets hot. If it doesn’t then there’s a big chance that an app is causing this and in which case you will have to manually uninstall any third-party app until you r phone does not heat up.

If it still gets hot even in safe mode then it’s time to do a factory reset on your device. Just make sure to backup all of your important data first.

  • Turn the phone off
  • Press and hold VOLUME UP and HOME (middle) button
  • Press Power until the phone vibrates
  • Wait until you see the Android logo then release all buttons
  • Select Wipe data/Factory Reset with VOLUME DOWN, press Power (right hand-side)
  • Select Yes –delete all user data with Volume Down and then press Power
  • After format, press Power again to reboot Power. (select reboot system now)

Galaxy S4 Blackout Issue

Problem: Hello, Found your article about the Galaxy S4 online useful, but it doesn’t address the problem I am experiencing. I am definitely cashing on my insurance and getting a new one instead of trying to get this fixed. Essentially, the phone will die without warning while some application is being used. So, I’m playing a game or trying to get Snapchat taking, or checking a website when the phone just goes black, and turns itself off. Then it won’t come back to life unless you plug it into the power supply. I reset the whole phone, and later disabled most useless crapware after  had this problem, but it doesn’t make much of a difference. If I’m listening to music, the phone will somehow work alright. Another issue is that if you’re making a video, and the power is drained, even if the file you were working on was 20 mins long, it will not be recorded if the phone dies. I would have expected Samsung to have programmed these apps to sense the power draining in order to save the files before turning itself off. Most macs do that. It works fine with the power supply, but as soon as that’s disconnected, it will quickly just vanish, especially if an application that seems to require some processing power is used. This never happened before, but it has now become quite annoying. I noticed that if ‘power saving’ is on, the black out will take longer to happen. With the ‘power saving’ off the phone will black out much more quickly. Thank you for your attention.

Solution: You mentioned that you reset your S4 and even disabled of the crapware which is a good move. Have you also tried replacing your battery with a new one? The battery could already be faulty which might be causing this blackout issue. One sign that your battery has already gone bad is that it doesn’t last long when taking videos or running apps. Then there’s also the indication that your device blacks out longer when power saving mode is on. When getting a new battery make sure to get an official Samsung product as this has been made specifically for your device and comes with a good quality.
