Note 2 “unfortunately android.process.acore has stopped”

Problem: Hi, I have a Samsung note 2 mobile I don’t know what happen to my mobile. I am not able to use my mobile whenever i am unlocking my phone then is written on my phone unfortunately android.process.acore has stopped. Please tell me what I will do to solve this problem.

Solution: This is an issue that is affects not only the Note 2 but other Android models as well. This issue occurs when certain apps or system processes that unexpectedly closes or stops. Some of the known causes are

  • App cache or data is corrupted
  • Third-party applications with software problems
  • Programs running in background
  • Incompatibility with app settings

In this particular case it is usually the Contacts application that is at fault which is why we will be trying to troubleshoot if first.

What we need to do first is make a backup copy of all your contacts

  • From the Home screen, press the Menu key.
  • Touch Settings.
  • Touch Accounts & sync.
  • Turn off all synchronization to Google accounts and T-Mobile Contacts Backup.
  • Return to the Home screen.
  • Open the App menu.
  • Touch Contacts or People.
  • If there are any contacts listed, they are stored on your phone (because you turned off the ones synced). From the menu, export them to the SD card to save them.

The next step is to clear the cache of the Contacts app.

  • From the Home screen, press the Menu key.
  • Touch Settings.
  • Touch Applications.
  • Touch Manage Applications.
  • Touch All.
  • Touch Contacts
  • Touch Clear data and Clear cache

Restart your device and verify if the error still exists. It should be gone by now. If the issue no longer exists then restore your previously saved contacts list.

Note 2 Equalizer Issue After 4.3

Problem: Hi, I run galaxy note 2 upgrade  from Android 4.2 to  4.3.  After upgrade all Equaliser function, (adjusting sound effect) will only reducing sound level of corresponding frequency.   In fact it makes it LESS “loud” on the opposite frequencies i want to adjust. example: if i want to add heights the bass goes down significantly, but no hights are added. same for adding bass: the heigts go down, but the bass level did not increase. if i turn the EQ off, the sound get much louder then, although i adjusted the typically “U” formed curve! Is There any fix?

Solution: This looks like an issue with the update itself. First try to check if there are newer updates for your device. These updates may contain improvements and bug fixes that may address this issue. Next, if you haven’t done a factory reset on your device then I suggest you do it now. This step is generally needed whenever various issues exist on a device after a major update. Data from the previous software version may still be residing in your device which may be causing the problem and a factory reset is the quickest way to solve this. Just make sure to back up your data first before performing this procedure.

  • Turn the phone off. If you can’t, remove and reinstall the battery.
  • With the phone still off, hold down the Power, Volume Up and Menu buttons at the same time for about 10 seconds. Release them when you see the green android logo. This’ll get you into the unlock/reset menu.
  • You can use the volume buttons to scroll up/down
  • Scroll down and select ‘Wipe Data/Factory Reset’. Use the power button to confirm selections.
  • Select ‘Yes – Delete All User Data’. Use the power button to confirm selections.
  • Select ‘Reboot System Now’. The phone then reboots to factory settings

Once your phone has fully rebooted after the factory reset check your equalizer settings if they work normally. They should be working right now. If not then you may want to try using several of the popular third party equalizer apps available at the Google Play Store.

Note 2 Flashing LCD

Problem: Hello. I dropped and cracked my screen for the Note 2 its flashing now (screen) blur then clear. When am using it, it’s clear. When I leave it (not on it) it goes blur. What must I change the LCD or screen. Please advice.

Solution: The shock from the drop may have damaged some components inside the device aside from its display. Your best option is to bring your phone to an authorized service center and have it checked since there may be a possibility that other components have been affected aside from the display.

Note 2 Memory Card Issue

Problem: Hi Droid guys, it’s been a while that I follow your topics and I find them very helpful but now I’m facing some problems with my Note 2 that I can’t find a solution. Problem#1: when I try to update a application it appears a message that says it’s impossible to proceed to the installation in the phone memory and neither to the sd card despite there is more than 1 GB on both. After a while I did realize that the only way to download the updates was to turn off my memory card, can you guys tell me why? My second problem I think is related to my first one because I can’t move application from internal memory to sd card and vice versa anymore. Thank you for your attention.

Solution: It seems that your SD card may be faulty. Try using another SD card on your device and check if the issue still occurs.

If the problem still occurs then you may want to try to do a factory reset on your device. This brings your phone back to its state when you first turned it on. Be sure to back up your data first.

  • Turn the phone off. If you can’t, remove and reinstall the battery.
  • With the phone still off, hold down the Power, Volume Up and Menu buttons at the same time for about 10 seconds. Release them when you see the green android logo. This’ll get you into the unlock/reset menu.
  • You can use the volume buttons to scroll up/down
  • Scroll down and select ‘Wipe Data/Factory Reset’. Use the power button to confirm selections.
  • Select ‘Yes – Delete All User Data’. Use the power button to confirm selections.
  • Select ‘Reboot System Now’. The phone then reboots to factory settings

Note 2 Takes Long Time To Charge

Problem: Hello man. I am in trouble. I have a samsung galaxy note 2 gt n7100 . I bought it 8 months back. It used to get fully charged from 10% in about 2.5 hours. But from last week it is taking about 5 hours. Battery discharge timing is absolutely the same. What can be the problem? Plz help me with it

Solution: When your phone is taking a long time to charge then one of the primary suspects is the battery itself. This is because the constant charging and discharging will have a deteriorating effect on its lifespan. Normally it would take around 2 years for this to be noticeable however in your case it happens on the 8th month. What I suggest is to get another battery (one officially made by Samsung for this device) and use it on your phone. Try to observe if the issue still occurs. Make sure to use the original charger as a replacement charger may carry a different voltage. As much as possible try charging using the wall charger instead of plugging to the USB port of a PC.

Note 2 Some Contacts Vanished After Update

Problem: I have been using a note 2 for a year or so. It has been automatically upgraded Android 4.3 recent lyrics. My problem is that some saved contact names and telephone numbers have vanished. How to solve this. Thanking you.

Solution: Try rebooting your device first. This helps clear out some data that may not be needed but are still residing in the memory. Once your device is on check if there are any new updates available. These updates will oftentimes contain improvements and bug fixes that may resolve the issue.

Since you performed a major software update on your device try to check which contacts your phone is displaying. Most of the time the displayed contacts list will change making you think that your contacts have vanished. Click on Contacts then on the three dots to bring up a menu list. Click on Contacts to display and try to switch between each of the entries (Google, SIM, and Phone Contact). One probable scenario is that you may have saved all your contacts in the SIM while your phone is displaying the contacts list that are saved on the phone.

Note 2 Cannot Change Wallpaper

Problem: Problem: Hi, I have a Note 2 and I’m experiencing a problem with the wallpaper that appears on the display.  Problem is I cannot get rid of it. I’m afraid it’s some kind of Malware. I tried using task Manager to locate the program that loads it. I can’t find the image either. Help please. Thanks.

Solution: Try changing your wallpaper manually and see if the present wallpaper gets changed.

  • From the home screen, tap the Menu key.
  • Tap Set wallpaper.
  • Tap the desired wallpaper option.
  • Tap the desired wallpaper location.
  • Scroll to the desired wallpaper and tap Set wallpaper.
  • The wallpaper is now changed.

Are you using a third party launcher on your device? This may be the cause as to why the wallpaper can’t be changed. Try to uninstall the launcher or reset your app preferences. To reset app preferences follow the steps below.

  • Click Settings
  • Click Apps
  • Click the three dots
  • Click Reset app preferences

If you have a third party launcher installed and you click the home button you will be asked which launcher to use. Click on the default launcher for your device.

If all else fails and the wallpaper can’t be changed then it’s time to perform a factory reset on your device. Be sure to back up your data first.

  • Turn the phone off. If you can’t, remove and reinstall the battery.
  • With the phone still off, hold down the Power, Volume Up and Menu buttons at the same time for about 10 seconds. Release them when you see the green android logo. This’ll get you into the unlock/reset menu.
  • You can use the volume buttons to scroll up/down

Note 2 Difficult to charge, Screen Goes Black

Problem: Hello 🙂 I would like to ask you some questions about my Samsung Galaxy Note 2. So this is almost the first year of me buying this phone and it was working very very very well at first. After like 7 months or something it started to kinda piss me off haha. First its` charger didn`t work , or maybe the phone`s charging part isn`t working I still don`t know , but I started using another charger instead of the original one and somehow it`s working a little bit.

The phone won`t work , like , the screen is all black but the blue light at the top is still working it`s coming and going and I really don`t know what to do , the phone didn`t fall it , no liquid was poured on it , I tried to charge it but still , nothing.. Can you please help me as soon as possible ? :\ Thank you 🙂

Solution: Try taking out the battery from your device and leave it out for 3 minutes. While the battery is out press the power button and hold it for 3 minutes. Replace the battery and try turning it on. If the screen is still black connect a wall charger to it and try charging it for 30 minutes. The battery may be low on charge which may be the reason why the screen is black. Check if there is any charging indicator.

If after 30 minutes your device still has a black screen then you may want to perform a factory reset. Backup all your data first using the latest Kies software installed in your PC. Just follow the instructions provided once you run Kies.

  • Turn off the device.
  • Press and hold the following three buttons at the same time: Volume Up key, Home key, Power key.

Note 2 Battery Level Incorrect

Problem: I Have a problem with my Galaxy Note 2, it has something to do with the Battery. The back cover of my phone was broken and the battery kept on falling out. I’ve since got a new case but something weird is happening, my phone can’t read the battery properly. For example, as soon as i turn the phone back on and plug the charger in, the phone would say something ridiculous like having 80% or something despite only having just run out of battery. And the phone would freeze and/or turn itself off even though it would say it has 20%-30% and even over 40% left. Does anybody know how to fix this? would simply getting a new battery help?

Solution: It appears that you may already have a faulty battery. Replacing it with a new one will most likely solve this issue. Be sure to buy an original Samsung battery and make sure you use the original charger.

Note 2 Display Won’t Turn Off

ProblemI’m having a problem with my device lately. The screen no longer turns off after getting a message or anything. The only way to turn it off is to manually lock the phone with the lock button. Any fixes?

Solution: Have you installed an app lately that may be causing this issue? Try starting your device in Safe Mode and see if this issue still occurs.

  • Turn off the Galaxy Note 2 by pressing the Power button (positioned in the right edge of the device). Tap Power Off from the choices that will appear followed by OK.
  • Once the device successfully shuts down, press the Power button again, but this time, keep your finger pressed on it together with the Volume Down button.
  • Let go of the Power button when you see the Samsung Galaxy Note II logo but do not let go of the Volume Down key yet.
  • After that, you will see a status message telling you that your Galaxy Note 2 is now in Safe Mode. Let go of the Volume Down key and tap the OK button.

If the issue disappears then you will have to search for the app that is causing this and uninstall it.
