To prevent from your screen flickering issue in android devices, you need to activate the disable hardware overlays in your device.
To disable hardware overlays (HW overlays) on a mobile, you can do the following:
Firstly, you need to 'Enable Developer options'
To enable the developer option,
- Goto Settings
- Tap on About Phone
- Tap on Software Information
- Tap on Build number (9-10 times) until you see the "You are now a developer!" message
- Enter your screen lock pin, if required
- Now Developer options is enabled in your Settings
- Move back to Settings
- You'll see Developer options at the bottom of all the options, just below the about phone option
- Tap on developer options
- Goto Hardware accelerated rendering section
- Now, Enable the Disable HW overlays option
What does "disable HW overlays" do? Can it affect GPU lifespan in the long term? Is it battery draining?
"Disable HW overlays" is a developer option in Android that allows you to disable the hardware overlay feature. When this option is enabled, it affects how apps display content on the screen. Here's what you need to know about "disable HW overlays":
Functionality:
The hardware overlay feature allows apps to display content on the screen using less processing power. It achieves this by giving each app its own portion of video memory, eliminating the need for constant collision and clipping checks. Disabling HW overlays means that apps will share video memory and have to perform these checks, potentially impacting performance.
Impact on GPU Lifespan:
Disabling HW overlays does not directly affect the lifespan of the GPU (Graphics Processing Unit). The GPU is designed to handle graphical computations, and enabling or disabling HW overlays does not significantly impact its longevity.
Battery Drain:
Disabling HW overlays can potentially lead to increased battery consumption. When the hardware overlay is disabled, the system relies on GPU rendering for composition, which may consume more power compared to using hardware overlays. However, the impact on battery life is generally minimal and may vary depending on the device and usage patterns.
In summary, "disable HW overlays" is a developer option that affects how apps display content on the screen. It may impact performance by requiring apps to perform collision and clipping checks. However, it does not directly affect the lifespan of the GPU and may have a minimal impact on battery life.
