The bank app application cannot be used on the root device, and the fundamental reason is security. Not only CCB, but also the applications of other banks cannot be used on the root equipment. One is to ensure the safety of customers' funds from the source, and the other is to technically reduce the risk of bank account theft.

Let me briefly explain that the application of China Construction Bank cannot be used on the root device: first, open the CCB app and click My-+-Intelligent Assistant, as shown in the following figure:

China Construction Bank app

Then open the smart assistant and enter the question to be consulted: What should I do if the mobile banking reports that "jailbreak equipment is not supported"? The official reply is as follows: If there is an error of "jailbreaking equipment is not supported" when using mobile banking, it is to ensure the safety of customer information and protect the operating environment of CCB mobile banking, and related operations on jailbreaking mobile phones are not supported.

Finally, for similar questions, you can click to pay attention to the following second question: What if mobile banking reports that the root device does not support it? The official reply is shown in the following figure: If there is an error in using mobile banking that does not support the use of root devices, it is because the Android system may be attacked by malicious software after being rooted. In order to ensure the safety of your funds and eliminate risks from the source, please use a non-root mobile phone. As for whether the mobile phone device can be restored to the state of not being rooted, please consult the mobile phone brand.

Therefore, once the mobile app of CCB detects that the mobile phone is root, it will report an error and cannot be used. Therefore, in order to ensure the normal use of your related bank account functions, please ensure that your mobile phone has not been modified by root or jailbreak.
