The "always exposed" camera lenses on the P30Pro is a problem as tend to need a wipe every time you want to start a photo session. There doesn't appear to be a case on the market that covers the lenses until they're needed, precious is the glass that is the eye of the camera!

Based on the GSM standard, it is deemed as a 3G mobile network standard. It has been developed by the 3GPP and its major advantage is the provision of greater bandwidth and spectral efficiency, due to the W-CDMA technology. The battery type is determined by its structure and more specifically, by the chemicals used in it. There are different battery types and some of the most commonly used in mobile devices are the lithium-ion (Li-Ion) and the lithium-ion polymer battery (Li-Polymer).

The higher the resolution is, the greater the detail of the displayed content. Information about the width, i.e. the horizontal side of the device when it is used in its standard orientation.

The images below show the test points for different Kirin-based Huawei smartphones. Visit iFixit for instructions on disassembling mobile devices. A CPU core is the processor unit, which executes software instructions. Presently, besides single-core processors, there are dual-core, quad-core, hexa-core and so on multi-core processors. They increase the performance of the device allowing the execution of multiple instructions in parallel.

The ISO rating or number is an indicator of how sensitive a camera's image sensor is to light. Image sensors operate within a specific ISO range. The higher the ISO rating is, the more sensitive to light the sensor is. The rear cameras of mobile devices use mainly a LED flash. It may arrive in a single, dual- or multi-light setup and in different arrangements. This SAR rating shows the maximum level of exposure to electromagnetic radiation taken when the device is placed next to the ear. The applicable limit for the US is 1.6 W/kg per 1 g of tissue. In the US the FCC tests and sets the SAR limits for all mobile devices, which are controlled by the CTIA. Information about the electric current (amperes) and voltage (volts) the charger outputs. The higher power output allows faster charging.
