A2 Headphones Questions and Answers

Q : How to get a clearer effect ?
Since the VR lens will magnify the pixels, scratches and dust spots on the screen of the mobile phone, the following unclear phenomena can be solved accordingly :
1/ Screen graininess is obvious : If the pixel density of the mobile phone screen is lower than 500PPI, the graininess will be more obvious. Screen Pixel Density Calculator
2/ Rhombus or rectangular grid : This is the grid line of the touch screen channel. Low-end mobile phones and non-original touch screens have poor anti-shadowing process, and it will be more obvious by zooming in or viewing from a certain angle.
3/ Partially irregular lines and spots : scratches, dust, etc. on the touch screen after magnification.
4/ Color spot : It is mainly the light refraction problem caused by the uneven thickness of the mobile phone protective film and the internal stress of the material.

The wrong DPI parameters of the mobile phone obtained by the software lead to ghosting : Some Android mobile phones have parameters such as screen size and DPI that are inconsistent with the actual parameters, which will cause the application to obtain information such as screen size and DPI that are inconsistent with the real object, resulting in ghosting.
