Samsung uses a Region Lock to prevent phones from being traded outside the intended region. You can recognise a Samsung smartphone with a Region Lock by the sticker on the box with "EUROPEAN SIM CARD ONLY".
This can cause problems if you want to use a non-European SIM card. Fortunately, it is very easy to solve the region lock. All you have to do is make calls for a total of five minutes with a European SIM card. After that, you can use any SIM card you want in any place you want. So it is important that you do this before you go abroad where you are going to use a foreign SIM card.
The Europe region includes all countries within the EU, plus the following countries: Lichtenstein, Iceland, Norway, Switzerland, Albania, Andorra, Bosnia and Herzegovina, Macedonia (F.Y.R.O.M.), Monaco, Montenegro, San Marino, Serbia, and Vatican City. So in these countries, you don't have to worry about the region lock.
Besides the internal storage of your device, you can also use Cloud Storage. Here you can upload your photos and videos, so they no longer have to be on your phone. They remain available on your phone via the Cloud, but do not take up any more space on your phone. In this way, your phone will stay fast and your storage will become much less full. Examples of Cloud storage are iCloud, Dropbox, Google Drive, and Microsoft OneDrive.
If you get the notification 'camera error' this is often easy to fix. You can first try to remove the data from the camera application and do a software update. To do this follow these steps:
If these steps do not work, there is another way to fix the error. Resetting your device to factory settings almost always solves the problem. Please note: you may lose your applications and data. So first make a backup. A reset can be done as follows:
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.
