In fact, normal mobile phone screen protectors only have right-angled sides, 2.5D and 3D, which refer to the curvature of the edge of the mobile phone screen protector.

Most non-smart phones and smart phones use the CPU of the British ARM company architecture. Smartphones have a higher frequency, run faster, process tasks faster, and make daily life more convenient (such as the Nokia n81 with a frequency of 369 MHz); non-smartphones have a lower main frequency and run slower (such as the Nokia 5000 The main frequency is 50 MHz).
