360 mobile phone can't send text messages.

Cell phone crash is a common problem, but there is no need to panic. Most problems can be solved by following the steps below. If it really doesn't work, go to a professional!

Troubleshooting of software problems

First of all, think about whether there is some software behind this. If so, it is probably a compatibility problem. Try uninstalling it or changing it to the same type of software.

Optimize equipment system

Secondly, optimize the equipment system to make the mobile phone smoother. You can use the software such as Le Security and 360 Mobile Security Guard to give your mobile phone a regular "physical examination" to ensure the stability of the system. Close the unused background programs, release more running memory, and make the mobile phone run more smoothly. Uninstall infrequently used or rarely used software to prevent them from secretly starting and occupying memory. With the help of LeSafe's self-startup management function, the startup project is restricted and the running memory is further released.

Back up data and restore factory settings.

If the problem still exists, please back up the data first! Then restore the factory settings. Remember to back up important information such as contacts and text messages, otherwise it will be deleted.

Please find a professional to solve the hardware problem.

If all the above methods fail, it may be a hardware problem. Please send your mobile phone to Lenovo's authorized service outlets, and professional engineers will help you detect and handle it.
