Smartphone technology has come a long way, but today, of all times, probably the most alarming disadvantage that users could be facing is "extra physical buttons". This is now becoming a season for Samsung and Google phones to clamour for extra buttons. These extra buttons can either make a good or bad case for a game change for convenience, experience, productivity, and accessibility for the users.

Why Need Specific Buttons on Samsung and Google Phones
Having said that, operations are dependent on smartphone gestures solely. But then, this also requires a lot of time, when nothing much can be done except waiting, and, many a time, when an instant action is required in an emergency moment, there is no time. Example: different gestures to launch the camera, take a screenshot, mute the phone, and launch Google Assistant/Bixby are remembered by people.
Had there been an add-on physical one or two buttons, they would have clicked once to open any of the above functions. The S Pen is gradually becoming less frequent on new Samsung flagship devices, while, it boasts some really amazing software features, but on a Google phone, controls are clearly not physical.
Need for Custom Buttons for Shortcuts
Any extra programmable/custom buttons on Samsung or Google-enabled devices can enable users to assign any action they want to the button. For example, the following actions may be carried out:
Open camera
Record audio
Switch flashlight On/Off
Take a screenshot
Record screen
Quick toggle for airplane mode
Make an emergency SOS call
Not only will it reduce the dependence of users on the power-volume button, but it will also speed up task execution within the phone.
Huge Advantages for Gamers and Content Creators
Most gamers want an added trigger button on their phone. This means that with an extra button, the gameplay in PUBG, COD, or any other shooting game will be easy. The content creator would easily press start recording, such that Vlogging would appear smooth.
Improvement on Accessibility and Safety Features
The additional button would prove to be of great help to users with accessibility requirements. Elderly or disabled persons can easily perform certain tasks. There will be an SOS button on it that allows them to quickly seek help in case of an emergency. This is much needed in the smartphone world today.

Conclusion
If Samsung and Google actually want to genuinely jolt the user experience, they should add at least one customizable extra button to the phones. Such a step would make smartphone use more comfortable, and the user will feel, in part, tech-savvy. Time now- Samsung and Google; add extra buttons to the phones.
