It's such a cool thing to do now, but there's something that gets worse in a while. What do you know
I. Water protection: new machine ip69k, not forever ip69k

The new machine can be waterproof at the ip68/ip69k level by adhesive glue, seals, precision。

However, high temperatures, earthquakes and everyday aging are used over time to disable the water-resistant glue, to harden the seal, and to prevent water from dying。
You see the crazy water spray, it's new。
The real cell phone is a water-proof, hand-defunct, officially unpaved and more expensive to repair than the mobile phone。
Sound + motor: the new machine is rocky, secondhand "floating"
When you buy a new machine, double speaker stereo, exclusive game vibrates motors, listens and shakes。

A mobile phone for two or three years:


As a result, the reduced volume, the siltness of the sound, the vibrations, the poor sense of the hand are both original and unrepairable。
Iii. Screen: the more slow you use, the easier it is to step on
The screen is the most worn-out part of the phone。

In time:
These questions do not affect “original” labels, but seriously affect daily use。
Cameras: the new machine looks good and the second-hand is getting worse
The camera is also "consumable":


Looks like the camera didn't change, it's full。
Many people buy second-hand mobile phones, recognizing one standard: full original, unrepaired, functional, and feel comfortable using them as long as they are original. But i have to tell the truth today: even with the original second-hand phone, it's been a long time, and that's why i don't really recommend second-hand phones。
All these problems, mobile phones have been visible for about three years。
Most of the second-hand phones on the market happen to be this age。
It is unopened, unrepaired, full-fledged, but it is not malfunctioning, but it is difficult to use。
Last reminder
If you don't know how to check, you don't see loss, you really don't want to buy a second-hand phone。
Rather than looking at the “full original”, the length of use and actual wear and tear, that is the key to determining whether it works。
Save it, but don't save it to the end, buy a cell phone that looks good and uses it to pull。
