How to Change Touch Screen Sensitivity on Android Device – Guide
Well, you know that all smartphones including Android and iPhones come with default touch sensitivity which is usually good enough for most people. However, if you still feel that the touchscreen is not working perfectly, is too slow or too fast and you want to change your phone’s touch sensitivity, you can do this. Sometimes you will find that the touch sensitivity is too sensitive or not sensitive enough for your taste. You can change this by following a few simple steps on Android and iOS. You can change touch sensitivity on Android by going to language and input settings. This one feature is due to different settings in different phones. On our OnePlus smartphone it was in System. Some smartphones have a separate setting for this. You can search for “Language & Input” directly in Settings. If you want to be absolutely sure you’re touching the right thing, set the screen sensitivity to low and you’ll have to work harder to activate things. If you need a smoother touch because you just can’t move the screen, set the sensitivity higher.
hardware interrupts
In modern computing, a hardware device usually attracts the attention of the operating system by sending a hardware interrupt to the CPU. When a CPU receives a hardware interrupt, it immediately pauses whatever it is doing and instead executes an instruction path predefined by the operating system for the specific hardware interrupt (this is known in computer science as entering context of interruption). To better understand how this works, consider the following example: On a desktop computer, the user moves the mouse. The mouse device then sends a hardware interrupt to the CPU. The CPU then executes special code within the Operating System that reads the current mouse position and informs the program responsible for displaying the mouse pointer on the screen about this change in position. After completing this task, the CPU resumes its previous operation.
interrupt controller
Every complete computing platform, whether it’s a desktop PC or a mobile device, comes with a special hardware chip known as an interrupt controller. This chip is responsible for collecting interrupts from all devices connected to the system and sending them to the CPU. By being placed between the interrupt source and the CPU, the interrupt controller can prioritize interrupts and send them to different CPUs on a multi-core device.
stop balancing
By default, the Linux kernel assigns all hardware interrupts to the first CPU core at startup. However, this approach presents a rare but possible case: a single CPU core can process only one interrupt at a time. When there are a lot of hardware interrupts arriving at the same time, some interrupts will be delayed. A simple solution to this problem is to change the CPUs allowed to listen for an interrupt (CPU affinity) depending on the CPU load. This is known as interrupt balancing. In fact, desktop Linux distributions have been using this interrupt balancing tool for a long time. Recently, Qualcomm developers decided to enable an interrupt balancer on high-end devices with good results. However, most Android devices still do not feature an interrupt balancing tool.
