If you have problems with the Xperia Ear Duo and can no longer pair the headphones, for example, it makes sense to reset these to factory settings.

Note: All paired devices will be removed when you reset the Xperia Ear Duo!

Carry out factory reset Xperia Ear Duo

To do this, first remove the right earphone from the charger cradle. The LED display of the earphone will flash white twice when you switch on the earphones.

Now tap the earphone's touchpad three times quickly and hold your finger firmly on it the third time. Hold your finger on it until the LED lights up green four times.

This completes the reset to factory settings. The headphones will automatically restart and the blue LED should now flash.

This means that you can now pair the headphones again.

If you have an Xperia Ear Duo headset and it no longer responds correctly to control inputs or no longer plays music, you should restart it.

This can be done by means of a soft reset. Below we describe how to perform a soft reset on the Xperia Ear Duo:

Remove the right earphone from the charging cradle. The LED indicator should now flash white twice when the earphone is activated.

Press and hold the right earpiece touchpad with two thumbs and hold for a little more than 10 seconds.

The thumbs should be placed on both sides of the SONY logo, as this is the only way to detect the soft reset through the headphones.

The LED indicator on the earphone should now flash white twice again. The earphone will then restart and emit a sound.

This procedure must be performed for both earphones. Repeat the above steps for the left earphone of the Xperia Ear Duo Set.

The Call Waiting function tells the user during a call whether another call is being received. A short tone sequence is played on a Huawei smartphone.

Like many other users, you certainly use the messaging app WhatsApp on your smartphone. It's a great way to stay in touch with your friends and acquaintances.

If you don't want to be able to see at a glance who is sending you messages, you should hide them. But is that even possible? Can you hide chats in WhatsApp?

The answer is "yes". There's no special feature for that. However, you can use another function to do that. We would like to explain to you how this works:

Hide WhatsApp Chats - Tip

1. First open WhatsApp.

2. Navigate to the chat you want to hide.

3. Press and hold your finger on it, then select the "Archive" icon in the toolbar at the top.

4. The chat will be archived and appended to the bottom of the list of chats. The chat will no longer be visible, but only when you scroll down the chat list and tap on "Archived Chats".

But the whole thing has one disadvantage. As soon as the contact sends another message, the archived contact becomes active again and is at the top of your list!

Unfortunately, archiving chats is the only way to hide a chat in WhatsApp.

If you have a Samsung Galaxy S8, then this is equipped with a so-called OLED display. These displays have a particularly good resolution and colour brilliance, but are also susceptible to "burning in".

The term "burn in" is used when a pixel of the display can no longer display certain colors as it did at the beginning because it has displayed a certain color for too long.

This is the case, for example, with bright colors in combination with a high display brightness.

To prevent this from happening with your Samsung Galaxy S8, follow these instructions to prevent pixels from burning into the display.

1. Don’t set display brightness to maximum permanently

2. Keep screen timeout as short as possible - we recommend a maximum of 2 minutes

3. Use dark colors, especially for background images. This also prevents the background image from burning in.

4. With apps, such as navigation apps, you should make sure that they do without bright static control elements.

This is the case with Google Maps, for example! If you take these tips to heart, you shouldn't have any problems with the Samsung Galaxy S8's burn-in display.
