Do you hear a small noise from the inside of the device when shaking your Galaxy phone?
Sometimes we often wonder to hear a sort of rattling noise when we shake our Galaxy phone, though there’s nothing to worry about as your phone is absolutely fine, here we describe why this is happening.
The OIS (Optical Image Stabilization) feature may make a small sound inside of the device
In the Galaxy mobile phone, there is a component that functions as OIS (Optical Image Stabilization) whose function is to minimise shaking when taking pictures with the camera. If this small part is shaken while the camera is not operated, it may hit the internal structure and make a slight rattling sound.
One of the vital roles of OIS (Optical Image Stabilization) is a function that detects handshaking and corrects the lens by moving the lens in the opposite direction of the shake. Due to the different OIS sizes for each product, the sound may be relatively loud depending on the product. This is due to the characteristics of the OIS and it is not a product defect. Also notice that the sound does not affect the function and performance of the mobile phone.
What can OIS (Optical Image Stabilization) do?
Samsung’s Optical Image Stabilization uses a combination of hardware and software processing that is advanced enough to deliver clear and sharp photos even in low light, thanks to the big sensor on the Galaxy S and Note series. The multi-camera system offers dual OIS for steady shots whether you’re using the wide-angle or the tele-camera. So almost any time of day, your photos will come out as vividly as you remember the moment.
Note: The availability of this feature may vary by device and model.
Steps to activate eSIM on my Galaxy Z Fold 2
Your device includes an eSIM that works like a SIM card. You can use the mobile network after activating the eSIM or installing a nano-SIM card.
You can also activate eSIM and install a nano-SIM card so you can have two phone numbers or service providers for a single device.
Note: In some areas, data transfer speeds may be slower when two SIM cards are inserted into the device than when one SIM card is inserted.
How to configure the eSIM?
To activate eSIM, open Settings and touch Connections> SIM card manager> Add mobile plan.
-Go to Settings
– Connections
– SIM card manager
– Add mobile plan
When you find a mobile plan, follow the onscreen instructions to activate eSIM. If you have a QR code provided by your service provider, go to Settings > Connections > SIM card manager > Add mobile plan > Add using QR code, and then scan the QR code.
Note: This function may not be available depending on the region or service provider, including countries such as Guatemala, Ecuador, Costa Rica, Dominican Republic, Honduras, Venezuela, Panama, Jamaica, El Salvador, Nicaragua, Caribbean, Trinidad & Tobago, Puerto Rico.
Reason to not include earphones and a charger plug inside the box items
The Galaxy S21 series does not have earphones or a charger plug in the box. As earphones are not included with the purchase of your Galaxy phone, you should purchase compatible earphones or a charger separately if necessary. In-box items may vary depending on the model and region in which you purchase.
If you want to detailed description then please refer to this article which I exclusively made on this topic: Why isn’t Samsung including Charger plug inside the box – SamNews 24
Also, I would recommend that, before proceeding with the below steps, be sure that all devices’ software and related apps are updated to their latest version.
To update your mobile device’s software, follow these steps:
Step 1. Go to Settings > Software update.
Step 2. Tap on Download and install.
Step 3. Follow the on-screen instructions.
Some reasons to not include the charger as given below:
- Samsung discovered that many Galaxy users are reusing their earphones and chargers that they already have at home even after purchasing a new phone. Our past models already have standardized chargers, and these chargers are widely available at home.
- Samsung also applied a standardized, USB-C type charging port in 2017, so older chargers are still compatible with our newest Galaxy models. In addition, Samsung wanted to reflect the recent wireless earphone usage trend.
- Reflecting these usage patterns of customers, Samsung reviewed the composition of the products from various perspectives and is transitioning to the removal of a charger plug and earphones in our latest line of Galaxy smartphones.
- They also believe that the gradual removal of charger plugs and earphones from our in-box device packaging can help address the growing e-waste problem and remove any pressure that consumers may feel towards continually purchasing new chargers with new phones.
- Since they trying to eliminate unnecessary waste of resources by prioritizing compatibility between product components, and through these, Samsung is committed to providing the best possible experiences for our Galaxy customers.
Note:
- In-box items vary depending on the model you purchase, or the country or region you live in.
- Charger plugs are sold separately, and the price may vary by market.
Compatible earphones and chargers
The latest models from the Galaxy S21 series do not come with earphones or a charger plug (power adapter) by default, but if necessary, you can purchase them separately.
USB Type-C wired earphones that support digital output or wireless earphones such as Galaxy Buds, Buds+, Buds Live, Buds Pro, and Buds2 can be used with the latest phones.
Note:
- To use the 3.5pi earphones, you need the USB Type-C to 3.5pi earphone adaptor sold separately. Plug the adaptor into your phone first, and then connect the earphones to your phone.
- The device may not be compatible with earphones that use a different audio output method or were made by a different manufacturer.
- As some USB Type-C earphones and USB Type-C adapters may not be compatible with your phone and some features may not work properly, make sure they are compatible with your phone before purchase.
