This is a duplicate of #2845. @fauzimubarokk do you have any details on the devices this occurs on? Some devices simply have faulty keystore implementations - we make a best effort but if the keystore doesn't work there's not much we can do.

Here are the details of the devices :

Hmm. On previous projects I have seen that Oppo devices have been notoriously difficult to code around due to the way Oppo has customized Android. When it says 71% Oppo, does that mean there are other devices that have encountered this issue that makes up the rest of the 29%?
