Replace the old mobile phone with a washbasin and a kitchen knife.

Old mobile phones are replaced by washbasins and kitchen knives, which are all over the streets and lanes for recycling.

Many old mobile phones were eliminated by their owners because some parts were damaged. For these mobile phones, vendors often renovate them and sell them to some elderly people who don't have high requirements for mobile phones. For the elderly, as long as the phone is loud enough to make a phone call.

Although the old mobile phone has been damaged, some internal parts can still be used. After getting the old mobile phone, the vendor can sell these intact old accessories.

Some unscrupulous mobile phone repair shops will recycle these old parts at low prices and then install them as new ones on the repaired mobile phones. This is also the reason why sometimes the quality of mobile phones gets worse as they are repaired.

After replacing the damaged parts, some old mobile phones will be reassembled and sold to the elderly as new machines. If the vendors are highly skilled, they will assemble, renovate and sell themselves, and the profits will be considerable.

Mobile phone:

The mobile phone is a smart phone. Generally, the performance of smart phones is better than that of non-smart phones, but the performance of non-smart phones is more stable than that of smart phones. Most non-smart phones and smart phones use the CPU of British ARM company.

Smartphones have higher main frequency, faster running speed, faster processing tasks and more convenient daily life (such as Nokia n8 1 main frequency of 369 MHz); Instead of smart phones, the frequency is relatively low and the running speed is slow (for example, the main frequency of Nokia 5000 is 50 MHz).

Smart phones, like personal computers, have independent operating systems, most of which are large-screen machines, capacitive touch screens, and some are resistive touch screens, which are powerful and practical.

Users can install programs provided by third-party service providers, including games, which can continuously expand the functions of mobile phones and realize wireless network access through mobile communication networks.
