Camera code crashing on L.G G6 in Play store pre launch reports

i have an a simple app that takes a picture for sending it over to a server. The app works fine and all, but for some strange and unknown reasons it always crashes on LG-G6 devices in testing by google.
The pre launch report crash logs always points to following code which is setting FOCUS mode.
I have tried all flash modes yet the app crashes.
if(getPackageManager().hasSystemFeature(PackageManager.FEATURE_CAMERA_AUTOFOCUS)) {
parameters.setFocusMode(Camera.Parameters.FOCUS_MODE_CONTINUOUS_PICTURE);
camera.setParameters(parameters); //line 328
}
Following is the excerpt from crash log

Can anyone provide me with some insight? This issue has been pestering me for a while.
P.S i don't have a physical LG G6 device with me. I have tested the app on a slightly older LG device and the app ran fine.

Unity Android 6 Fragment$InstantiationException

recently (past few weeks maybe) most of the android 6 users of my app started to suffer from crashes. UnityPlayerActivity failed to start with exception logged: android.app.Fragment$InstantiationException.

Initially my first thought was permissions problem but I can't reproduce this error on any of my android 6 devices even if I deny permission (WRITE_EXTERNAL_STORAGE).
Is there is any workaround for this problem(if this problem is a common for Unity on Android 6)?
Thanks in advance!
PS:
Unity version 5.5.0f3,
Android version from crush reports 6.0

DeadObjectException with stacktrace pointing to : android.app.ApplicationPackageManager.getPackageInstaller

I'm seeing in crash being reported in crashlytics which has this stack trace which has no mention of my app code.
I have seen DeadObjectException with com.google.android.gms and there, the crash was triggered when removing listeners.
Also, everytime my app starts, I get the installer for logging purposes, i.e.
packageManager.getInstallerPackageName(my-package-name)
There is no callback associated with this call.
Crash is observed mainly on Lollipop and Kitkat, though few Marshmallow and Nougat users have experienced it too.
Has anyone experienced something similar?

Here are the Fabric crashlytics reason for this exception.
DeadObjectExceptions are usually a symptom of a problem occurring somewhere else (likely in a remote process). Even though this exception may be safe to catch, it's worth looking for problems in related services.
This error could mean one of two things:
1) There is a bug (which caused a crash) in an associated process.
2) The other process was killed by the OS.

E/AppWidgetHostView: Package name not found

I write an android App Widget and it works fine. After some time I had to change its package name But it works well yet. I already had getPackageName, and it prints the correct package name in the log, and still sometimes after I upgrade the app (or just run it on the device from AndroidStudio) the widget disappears. Later it got back after another upgrade.
this is my logcat :

Android 5.0.1 VerifyError?

I have just updated the OS on my phone to Android 5.0.1. Since this update, an app that I am working on, that is working perfectly fine on my other devices, is now throwing an error in 5.0.1 only. I have no idea what this error means, and it isn't pointing me to a suspicious line of code like it often does.
Has anyone seen this or know what it is about with the new 5.0.1?

For anyone else having any issues since the Android update, I have found and resolved my issue.
The allowed maximum method size has obviously changed. Some of my methods were quite large and complex, and this new limit was obviously exceeded.
This fix was to break larger sections of code into smaller sections.
Hope this helps someone.
