Most of the earliest desktop mobile phone stands are "herringbone" mobile phone stands, which have grooves for placing mobile phones and the back can be firmly supported. Advantages: small size, portable travel, not easy to lose; Stronger stability and skid resistance; The back can be adjusted at multiple angles as a support; The mobile phone tablet is universal. Disadvantages: some types on the market cannot be folded, which is inconvenient to store; Some brackets have grooves that block subtitles; The mobile phone cannot be charged when placed upright; It is best to choose a bracket with a groove and a non-slip silicone pad at the bottom to prevent the phone from bumping due to sliding.
