Coolpad mobile phones are considered to be upper-middle-class among domestic mobile phones, and the quality of the mobile phones is acceptable.
Coolpad is the mobile phone brand of Yulong Communications Company. The full name of Yulong Communication Company is "Yulong Computer Communication Technology (Shenzhen) Co., Ltd.", which was founded in April 1993.
Specific methods for judging the quality of mobile phones:
1. Look at the appearance.
The appearance involves many aspects, including whether the paint of the mobile phone is smooth, whether the brightness is consistent, and whether the shape of the light spots printed on the shell changes when the machine is moved horizontally to watch. Whether the LOGO is beautifully printed, whether the font size is consistent, and whether it is on the same horizontal line. Check whether the shell and the back cover are tightly connected, and whether the back cover can be opened and closed smoothly without looseness. Whether the gap between the button and the shell is tight and without burrs. Whether the edge of the screen is parallel to the edge of the casing, etc. In short, it is most intuitive to judge the quality of a mobile phone from the appearance of the manufacturer's workmanship.
2. Look at the system.
1. Turn on the phone and see how delicate the phone LOGO is on the screen to judge the effect of the screen. Most mobile phone manufacturers focus on the display effect of the screen after the mobile phone enters standby mode and ignore the effect of the logo. Most powerful manufacturers pay great attention to details, and the effect at the moment of turning on the phone is enough to affect the user's first impression of the phone.
2. After entering the system, look at the fonts. The fonts are very thin and have no jagged edges. The screen effect is relatively better.
3. Check whether the operation interface is user-friendly. Systems that are very cumbersome to operate are mostly written without considering user convenience. Of course, many people may find the operation of smartphones cumbersome.
4. Look at the processing speed. Except for smartphones, if the machine delays, pauses or freezes when opening various functions frequently, it means that the processing performance of the machine is not good.
3. Make a call.
The most important function of a mobile phone is making calls. Therefore, you can turn on the computer stereo or make a call when close to the TV to see if the interference is large. Cell phones with low interference will have relatively low radiation. At the same time, listen to whether the phone content is clear and whether there is any noise.
4. Look at the accessories.
It’s not about having too many accessories, it’s about being precise. Exquisite workmanship and effective accessories, even if there are only 3-4 types, are far more affordable than just giving away Bluetooth headsets, ultra-thick batteries, original cradle chargers, exquisite leather cases, mobile phone lanyards, etc.
