Description
### bytehook Version
1.1.2
### Android OS Version
13
### Android ABIs
arm64-v8a
### Device Manufacturers and Models
Samsung Galaxy A53
### Describe the Bug
Hooking no longer works when updating to v1.1.0 or above. `bytehook_hook_all` returns a pointer but hook never gets called.
Only log from bytehook is `bytehook version 1.1.2: bytehook init(mode: AUTOMATIC, debuggable: false), return: 0, real-init: yes`
v1.0.10 and below works, v1.1.0 and above broken.
Bug can be reproduced on other phones.
Please tell me instructions on how to troubleshoot deeper.
Contributor guide
Research direction
Start by reproducing the failure with bytehook 1.1.2 on Android 13 arm64-v8a, using bytehook_hook_all and checking whether its returned pointer leads to a callback. Compare the behavior with v1.0.10 and v1.1.0, then trace the version change that prevents the hook from being called; done means the regression is explained and hooking works again on the reported setup.
