Your phone's internal storage can become full by storing lots of apps, photo’s, video’s, music, or contacts. This is very annoying, because it makes your phone slow and you can't download new photo's or apps anymore. You can expand your phone's memory with a microSD card. This is a card that you can place in the slot of your second SIM card. This does mean that you can only use one sim card. You can also use cloud storage. You upload photo's and video's to the Cloud and then remove them from your phone. The files will remain available on your phone via the Cloud, but will no longer take up space on your device. This way, your phone stays fast and you have room for new apps, for example. Examples of Cloud storage are iCloud, Dropbox, Google Drive, and Microsoft OneDrive.
Of course, it is annoying when your storage space is full. Often you can solve this by placing a microSD card in your phone for extra storage space. Your phone uses hybrid Dual SIM. This means that the second SIM card slot is also where you place your microSD card. This means that you cannot insert two SIM cards and one microSD card at the same time. You can choose between one SIM card and a microSD card, or two SIM cards. Do you not know how to insert the microSD card in the compartment of the second SIM card? Then look in the manual of your phone. This is often explained. These manuals can be found on the page of the device on our website.
You can use two SIM cards with different phone numbers in a Dual SIM phone at the same time. Depending on the model, you can be reached on both SIM cards at the same time, or you can switch between them. This comes in handy if you have both a business and a private number, or a domestic and a foreign number. It depends on your device whether you can set up a separate ringtone for each phone number.
Switching between SIM cards and contacts is very easy, so you're always calling from the right number. The contacts are often sorted by SIM card. This way, you will always call your business contacts with your business number and private contacts with your private number. In a Dual SIM phone, you can also use only one SIM card.
Some phones have the front camera and proximity sensor in the display. The proximity sensor flashes as soon as you bring your phone closer to your ear. It then looks as if you have a dead pixel in the display.
That flashing white pixel is not a dead pixel but the proximity sensor that does its job of turning the screen off while calling to prevent unintended touching.
As a rule, water damage to any electronic equipment is not covered by the warranty. This is because water damage falls under user damage. The manufacturer cannot give a guarantee on this, because they cannot influence the use of the appliance.
Many devices, such as smartphones, smartwatches, and fitness trackers, have a watertightness certificate indicated by a code, such as IP68 or 5ATM. Water damage with these certified waterproof devices is also not covered by the warranty. This is because the waterproof seal of your device may be subject to wear and tear due to normal use. So always try to prevent your device from getting wet, even if it is waterproof.
