Our Android devices may be fast enough though the impatient human nature may make us feel that our devices are still not fast as we would want them to be. This would call for overclocking, which fortunately, is supported in Android devices. Overclocking is the act of making the PC of your device operate faster.However, it is important to note first that this process comes with its own risks such as overheating of the device which can affect the battery life and even cause instability in the device.The first step is getting the right kernel which will support the overclocking process as you modify the CPU settings on your Android device. There is the right kernel for each phone model.You will need to find your phone's model number, which you will find in the settings app under the 'About phone' label. It is also important to take note of the Android version that your device is running. In order to overclock your CPU, rooting will also be needed, although it's a risky process that is not covered by warranty. After this you will also need to install a custom recovery.Finding a kernel and overclocking your device involves no hassles though it's worth ensuring that you get a kernel from a reputable source and that it's compatible with your phone model and Android version.It is also worth ensuring that the kernel you choose comes with a companion app. Some kernels also come with dedicated software that helps you get maximum benefits out of them such as CPU main settings, overclocking slider, etc. Once you get the right kernel for your device, then you're set to go.When overclocking your phone, first your device needs to be rooted to pave way for flashing a custom kernel. After this, you need to install a custom recovery. The following are steps that you need to follow:
  1. Ensure that you've got a backup of all your data. This can be done through any of the related apps, PC-based solutions or custom recovery.
  2. After choosing the kernel, download it to your device or you can use a computer after which you will zip the file and copy it to your phone's root directory.
  3. Switch off your phone and perform a fastboot, which in some phones is done by the Volume and Power Down though some phones have different button combinations.
  4. When the fastboot screen is on, use Volume buttons to pick Recovery Mode then press the power button to choose it.
  5. After that, you can now enter your custom recovery.
  6. Press the install button then scroll to the specific place where you had saved the zip file of the kernel.
  7. Flash the zip file then wait for a success notification. Some kernels might take you through several screens such as the Wizard install. Also, some kernels will let you set the desired clock speed at this point for your CPU during the installation.
  8. Once the kernel has been successfully flashed, clear the cache.
  9. Head for the Advanced settings in the recovery and choose 'Fix permissions'.
  10. Restart your system.
If the kernel did not give you the chance to change the CPU settings during the install, you now have the chance to do so.Check for the settings that are used to manage your clock speed depending on the app that you are using. Do not start with a high speed percentage as it is good to ensure that your phone can accommodate the speed as it adds up. Start with the lowest speed at around 10%.However, do not expect your CPU to jump onto the new speed immediately. Give it time to adjust. It's also important to set the speed only on functions that deserve speeding up.If you notice any strange behavior with your phone, it's important to reduce the speed of the set overclocking. If this does not work, it's good to check whether the kernel you used is from a trustworthy source.

What's my model number?

There are several ways to locate your model number:

Option 1
On your device, go to Settings, then "About device" and scroll down to "Model number"
Option 2
Often times you can view the model number inside the device, by removing the battery
Option 3
Using Samsung's model/serial number location tool
