Samsung M21 On Off + Volume Flex – Restore Full Button Control

The Samsung M21 On Off + Volume Flex is a small but powerful part that connects the power and volume buttons to your phone’s internal system. Without it, basic tasks like turning your phone on, adjusting the volume, or locking the screen can become difficult or impossible. This flex cable helps bring back smooth, responsive control to your Samsung M21.

This flex lets you turn your phone on and off quickly, lock the screen to avoid accidental touches, and control volume levels during calls, while watching videos, or listening to music. It also makes it easy to switch between loud, vibrate, and silent modes.

Need to take a screenshot? With this part working properly, pressing the right buttons together captures your screen instantly. In emergency situations, fast access to calling options becomes more reliable with a responsive flex cable in place.

If your phone is lagging or facing issues, this part also helps with quick reboots, letting you restart the device without a full shutdown. It also gives better control over media playback—pause, skip, rewind, and play with just a tap.

For users who may struggle with fine movements, this flex cable ensures that the main phone functions stay easy to use. It also supports quick wake/sleep actions, and lets you double-press the power button to launch the camera without delay.

You can also use it to trigger shortcuts like Google Assistant or other custom functions. During calls, it helps answer and end conversations more smoothly.

Over time, the original flex cable can wear out due to regular use. Replacing it with a high-quality part like the Samsung M21 On Off + Volume Flex ensures your phone stays functional and user-friendly. This is a must-have component for repair technicians and anyone looking to fix their Samsung M21.
