We understand that it is very annoying when the storage on your device is full. Fortunately, you can solve this with your device by inserting a microSD card. Your device has space for two SIM cards at the same time, as well as a microSD card. This way you can be reached on both SIM cards and you don't have to worry about the storage space of your phone. If you can't find where to place the microSD card, check your phone's manual. It often explains this.
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.
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.
If you are returning or sending an Android device for repair, it is necessary to remove your Google Account from your device. To delete your Google Account, follow the steps below:
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.
