Bouncing back to your old phone is always an option. So, don&rsquo;t hold yourself back and grab your favorite Apple device.But before jumping into it, let me get you familiar with some of the iOS features that you may miss in the long run. And also being an iPhone owner, you better get along with this information.1. Shake to undoAfter writing a message, if you didn&rsquo;t like the content, there is no need to hit the backspace button to delete the whole text. You can simply shake your device and an &ldquo;Undo Typing&rdquo; pop-up option will show up. Just click that button and your content will vanish. In the case, if you wish to redo the typing, shake your iPhone again and you are good to go. iOS has it all.2. Disable push emailIt is widely known fact that &ldquo;Push Email&rdquo; is one of the features that constantly suck the battery juice and drain it in no time. You obviously don&rsquo;t want an app feature that keeps running in the background. For this, you can simply select the &ldquo;Fetch&rdquo; option in the phone setting, which will let you select designated intervals when your iPhone will check for emails. And if you are still not contented with it, just turn it off and then manually refresh the page for any new mail.3. Do Not Disturb ModeSometimes, having a smartphone can be a headache. Endless buzzing due to call, messages, and notifications can annoy anyone. To your rescue, iPhone comes with &ldquo;Do Not Disturb&rdquo; mode that can keep it silent for a particular period.

Your phone will ring after a set number of calls.4. Data backupBacking up your data and files is always a safe option.

Custom vibrationsDesignating a particular ringtone for a contact is something we all have witnessed in an Android device and iPhone. But iPhone has something more than usual. You can alter the vibration of as per your choice. It will let you set different vibrate ring for different contact.

Handle Siri&rsquo;s pronunciationSiri is a virtual assistant part of Apple Inc.&#39;s iOS, watchOS, macOS, and tvOS operating systems. The iOS assistant uses voice queries and a natural-language user interface to answer questions. But sometimes, it may pick something stupid which you don&rsquo;t intend. Words with altogether different pronunciation can be tricky for Siri.
