How To Fix Samsung Galaxy Note 2 That Freezes, Lags, Locks up, Reboots

Samsung Galaxy Note 2 in Recovery Mode
We have received at least 64 email messages asking questions about how to fix freezing, lagging, locking and random reboots in Samsung Galaxy Note 2. It just shows that performance issues are among the most common problems owners face every day. In this post, we will publish a few of the emails we receive before we present our recommendation how to solve them.


Email 1: I just got my Galaxy Note 2 about 5 months now. The first 3 months were smooth and I was totally impressed by the performance of the phone. It was only after 4 months that I noticed some lags and freezes, which I haven't experienced before, at least not too often. At times, the phone will be stuck for 10 seconds or so before I can continue what I'm doing. It may be a minor issue but it's very annoying and inconvenient. Do you know a fix to this problem?

Email 2: My Samsung Galaxy Note 2 started going crazy since last week. It freezes and reboots at least 3 times a day. Its performance now sucks compared to before. Any suggestions would be appreciated. Thanks.

Email 3: While my GN2 is a powerful device, I still experience some lags like I used to with my Galaxy S2. I don't know what the problem is because I'm not that savvy in terms of troubleshooting or finding the culprit. So I need your help to remedy my problem. Thanks in advance.

Email 4: I don't know if you guys are familiar with freezes and lags in Note 2 but I am currently experiencing them. They're very annoying considering I was enjoying the device for the last 8 months. I tried uninstalling apps I installed recently but to no avail. Please help.

Email 5: I haven't done anything with my Note 2 but yesterday it started to reboot itself automatically. I tried checking the battery and it was still in 73% so I'm sure it wasn't a power source problem. Do you guys happen to know what's causing this?

Possible Causes

·         Temporary device issue.
·         Too many applications open or running in the background. Not enough RAM to complete the requested action.
·         Your device's software (firmware) is not up to date.
·         Physical or liquid damage is present on the device.
·         You are using a non-Samsung OEM battery or charger.
·         Network conditions can affect the performance of apps that use mobile data, your web browser, for example. Your device may appear to not be responding while these applications load information from the web.
·         The device has been rooted and you have installed a custom version of the Android™ operating system.
·         Third-party application is causing an issue.
·         There is not enough internal memory available on your device to complete the requested action.
·         There is an issue communicating with your memory card.
·         The touchscreen is not responding properly, possibly due to a case or screen protector.

Before You Begin

·         With the device still on, remove the battery for 30 seconds. After the time has elapsed, replace the battery and power on the device.
·         Check for any available software updates for your device at Samsung Support.
·         Verify the device has no physical or liquid damage (for example, has not been damaged by dropping or exposure to moisture).
·         Verify that you are not connecting to or using any non-Samsung OEM accessories with your device. Non-Samsung OEM accessories can cause unwanted behavior. Disconnect or remove any non-Samsung OEM accessories.
·         Verify that you have adequate signal strength when using data-intensive apps.

Troubleshooting Guide

Step 1: When did the problem start? Remember the time when the problem first manifested. With that in mind, also try to remember things you did with your device prior to the problem.

Step 2: Uninstall suspected apps. If you've installed applications before the issue started, try uninstalling them to see if they're the ones causing it. If you can't remember the apps and you want to confirm if the problem originated from third-party apps, boot the Galaxy Note 2 to safe mode.

Step 3: Stop applications running in the background. Perhaps there is a lot of applications running in the background, try closing them to see if the freezing or the lagging is solved. From the Home screen, press and hold the Home button until you can see recently accessed apps. Swipe each one to close them. Or you can go to applications menu and force stop apps you don't use. It may take time to do this but it's worth it.

Step 4: Make TouchWiz faster. With TouchWiz UI running on top of the stock Android interface, the Galaxy Note 2 could also be plagued with performance issues especially when TW starts to slow down. Try to go to applications manager and find TouchWiz then clear its cache and data. Please note that clearing data may delete your home screens, so beware.

Step 5: If all else fail, factory reset your phone. The factory reset will bring the phone back to its original settings; a setup which everything in it works at their optimal performance. But we would like to emphasize that this is the last resort.
