“When you modify a certain piece of hardware for better performance, it is often referred to as "tweaking" it. Overclocking the computer's CPU or changing jumper settings on the motherboard are common examples of hardware tweaking. Removing system limitations and adding plug-ins or extensions to a computer's operating system are types of software tweaking.”
Before learning hacking, let’s make sure that your device is responsive and free from lags. To do this, you need to tweak your device. This tutorial is for non-Rooted devices. First things first, let’s ask: what causes android to lag? “Your Android phone was probably fast when you first bought it, right? Then over time it began running more slowly. This is a common problem and nothing to worry about.” -Scott Adam Gordon (www.androidpit.com). There are common reasons why your device is lag such as: It can be cause by an App, Too many applications running on background, and/or the system itself.
HOW TO FIX
Method 1: Uninstalling, Stopping, and/or Freezing Applications
Method 2: Disabling animations – Enabling Developer Option
Disabling animations could help your device run faster. To do this, you need to enable Developer Option. On Android 4.2 and higher, you must enable this screen as follows:
Note: If your device is lower than version than 4.2, search online on how to enable Developer Option.
Method 3: Install these apps to boost device performance.

There you go! Your device should be faster now! If you still don’t feel any difference, don’t worry this is not hacking yet. Later, we’ll going to hack your device’s system.
