Before making a purchase, it is important to check the version of the device for which you are buying the part. Compare the desired model with the description in the title. If you cannot locate the model (in the format, e.g., Axxx F/G/M, etc.) in the settings, use the IMEI number to find it. This process ensures that you get the correct part for your device. The Service Pack refers to original spare parts provided by the manufacturer and are identical to those installed factory-wise in the device. Using a Service Pack ensures that the repair is carried out with the highest quality components, guaranteeing optimal performance and durability.
