My iPad has been showing distorted colours for almost a month.

Soft reset your iPad by pressing the Sleep/ Wake button and the Home button simultaneously. Let go only when the Apple logo appears. See if the problem is solved. If not, you may have accidentally dropped your iPad and it will cost you quite a bit at the service centre. There is just one option left. Give the back of the iPad three hard whacks on your thigh. You could also tap it with your knuckles, but make sure to tap it pretty hard. If you are lucky, the problem should go away for good.

CONTACT CABLE

How should I transfer my contacts from a Samsung feature phone to a smartphone with another SIM card?

Swarnendu Bhattacharya

Connect your feature phone to the computer using the USB cable. Go to contacts and choose to export the list as a CSV file. Remember where the file is saved on the computer. Open https://contacts.google.com on your web browser and sign in to your Google account. On the left of your screen, expand More and click on Import. Choose CSV or vCard file from the window that opens. Find your CSV file and upload it to Google. You should find all your contacts on the smartphone after you set up your device with your Google account.

ENCRYPTED MAIL

Between Gmail and ProtonMail, which is more secure?

A. Ghosh

If you don't want anyone snooping on your messages, you will need a secure email provider such as ProtonMail. No one, not even its employees, will get hold of your messages as the company provides end-to-end encryption. Since no logs are maintained, your email can never be traced back to you. ProtonMail is available on your computer through its website and as an app for Android and iOS devices. The free version offers only 500 MB of space.

HIDE PROFILE

How can I hide someone's WhatsApp profile picture from my phone?

Komal Azad

You cannot do it. Only they can decide whether to display it or not. However, you can ask that person to set the privacy options for the profile picture to My Contacts and then delete your name from the contacts list. This way the picture will not show in your app.

SPECIAL REBOOT

My Moto E with Android version 6.0 shuts down own and restarts automatically, two to three times a day.

Press the volume down button for about five seconds and, still holding it, tap the power button. You should see several boot options. Use the volume down rocker to scroll to Recovery. Press the volume up button to select it. You will see the Motorola logo followed by Android lying on his back with an exclamation mark. Now hold the phone horizontally. Press the volume up key for about 15 seconds. Still pressing it, tap and release the power button. The display will show several menu options with the text in blue. Use the volume down key to scroll down to 'wipe cache partition'. Select this with the power button. This will wipe out all temporary files causing the phone to malfunction. Soon after, the device will reboot and power up normally.
