Huawei was banned by countries like the US, along with some of its allies, due to concerns about national security and potential espionage . Specifically, the US and its allies feared that Huawei's equipment could be used by the Chinese government to spy on or sabotage critical infrastructure. These concerns stemmed from Huawei's close ties to the Chinese government and its growing presence in global telecommunications networks.

Here's a more detailed look at the reasons and actions:

National Security Concerns:

The US and its allies expressed concerns that Huawei's equipment could be used by the Chinese government to spy on communications or access sensitive information.
Espionage and Sabotage:

There were also fears that Huawei's equipment could be used for espionage or sabotage, potentially impacting critical infrastructure like telecommunications networks.
US Restrictions:

The US government imposed various restrictions on Huawei, including placing it on a trade restriction list, which meant suppliers needed a special license to sell to Huawei.
Global Pressure:

The US also pressured other countries to block Huawei from their 5G networks, citing national security concerns.
Criminal Charges:

The US Department of Justice also brought criminal charges against Huawei and its officials for financial fraud and sanctions violations.

Why is my Huawei Mediapad so slow?

Insufficient memory can also cause the system to run slowly. Open Phone Manager/Tablet Manager, touch Cleanup, and delete unnecessary files as prompted to ensure sufficient storage space. (It is recommended that you reserve more than 20% of the storage space.) Too many apps will occupy a large amount of memory.
