Many people have already bought the iPhone 13 line of smartphones and shared their impressions. As is often the case, satisfied users rarely make reviews, but if a person does not like something, he considers it his duty to tell everyone about it.

When the new iPhone 13 is unboxed, many users confirm that they have detected manufacturing and quality control issues. Dust on the camera under the protective glass is often discussed.

In addition to the dust on the camera, some netizens have encountered scratches on some smartphones. Pro models have a shiny stainless steel side bezel that is easy to scratch even during assembly. Scratches can affect the resale value of the device. If there are marks on the frame, these are not scratches, they may be adhesive stains that can be removed by wiping with a soft damp cloth.

Additionally, the iPhone 13 has a problem with the loose connection between the screen and the bezel. Some netizens reported that the standard A4 sheet of paper easily fits into the thick gap.

After receiving the iPhone 13, many users began to complain about the weak network signal: “The iPhone 13 has a worse signal than the iPhone 12, so you should pick up two mobile phones at the same time.” A mobile phone will display a cellular signal but there are times when it will not be able to receive messages and calls.
