In order to enhance the competitiveness of products, many mobile phone manufacturers will provide firmware upgrade services to the classic models from time to time. However, many mobile phones always have some bugs after going through a large version of the system update. Take Huawei Glory 8 as an example. After updating EMUI 5.0, Alipay fingerprint authentication failure (Figure 1) is likely to occur. Is it only possible to restore factory settings at this time? When the phone is inexplicably problem, restoring the factory setting is the only way. However, like the above problem of fingerprint verification, resetting the mobile phone due to it is somewhat uneconomical. In fact, all the problems with Alipay fingerprint verification can be solved by the following two ways. First of all, check whether the mobile phone is ROOT. ROOT system will cause inexplicable fingerprint function. If the mobile phone does not have a ROOT, you can go to Settings → Huawei Accounts, find and enter Account Protection (Figure 2), and delete the current device in the device list (Figure 3). After restarting the mobile phone, log in to the Huawei account again, and then open Alipay to proceed with the fingerprint setup. hint Although many Android phones are equipped with a fingerprint recognition module, they cannot find the option to open fingerprint payment in Alipay or WeChat. There are two possibilities for this problem. The first is that the mobile phone manufacturer has not been authorized by Alipay or WeChat to open the fingerprint payment function (no solution). The other is that the Alipay or WeChat version is not correct. Please download the latest version of the APP from the mobile phone's own app store. Amorphous Iron Core For Car Audio
