Why is ZTE u808 mobile phone stuck and slow?

First, uninstall junk applications and release system resources.

A large number of junk applications are preset in the new mobile phone, which not only wastes CPU, but also increases power consumption, even steals traffic and disperses the notification bar, seriously affecting the experience. After getting root permission, it can be achieved with the help of a third-party mobile assistant. What if you don't have root privileges? In fact, for Android 4.0 or higher mobile phones, you can achieve your goal without root. Just go to System Settings → Applications → Select "All", then find the junk application and select "Disable"!

Second, rationally optimize the management of mobile phone storage and memory.

1, if nothing happens, don't kill the background process, thinking that this can speed up or save power for the mobile phone. Background caching process is a good optimization mechanism for Android. The purpose is to start the program faster next time. You have to end people easily, don't you ...

The memory mentioned here refers to the storage memory of the mobile phone itself. Is it better to install the software in the fuselage memory or expand the memory card? Suggestions are: commonly used software can be installed in your own memory, and infrequent or large-scale games can be moved to an external memory card, which not only solves the problem of insufficient memory, but also takes care of the running speed of commonly used software!

Third, mobile phone antivirus and security protection software are indispensable.

Computers need to be protected by killing software, and the era of smart phones is also essential! Now there are a lot of malicious Android applications on the Internet, even virus Trojans, which have caused great hidden dangers to the security and privacy of our mobile phones.
