Your phone's storage space can get full by storing lots of apps, photos, videos, music, or contacts. This is very annoying, because it makes your phone slow and you won't be able to download new photos or apps. Unfortunately, your phone's memory cannot be expanded with a memory card. But there is another solution: use cloud storage. You can upload photos and videos to the Cloud and then delete them from your phone. The files remain accessible on your phone via the Cloud, but no longer take up space on your device. This way, your phone stays fast and you have room for new apps. Examples of Cloud storage include iCloud, Dropbox, Google Drive, and Microsoft OneDrive.
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.
Currently, SIM cards are available in three different formats: regular, micro, and nano. If your SIM card is too small for your phone, you can use a SIM adapter. This way, the SIM card will fit in your phone again. If your SIM card is too big, you can cut it with a SIM card cutter.
Additional to the internal storage space of your device, you can also use Cloud Storage. This is where you can upload your photos and videos, so they no longer need to be stored on your phone. They remain available on your phone via the Cloud, but don't take up any space on your phone anymore. This way, your phone doesn't slow down and you'll run out of storage space a lot less quickly. Examples of Cloud storage include iCloud, Dropbox, Google Drive, and Microsoft OneDrive.
