android studio logcat does not show the reason of crashes when i run my app on a real phone

Question

I have a strange problem. when I run my app on Genymotion with android 4.1, everything is good and Logcat works fine and shows everything. but when I run the same app on a real phone(Huawei honour 7 with Android 6), and my app gets crash, logCat does not show the reason for that crash. in the other word, log cat does not show Exceptions. can anyonehelp me?thanks

maybe be useful:

logCat After a crash:

build.gradle(module app)

apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    defaultConfig {
        applicationId "my.application.id"
        minSdkVersion 15
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    ....
}

Best way to fix this to invalidate caches, may it will worked for you.

Go to FILE -> click "INVALIDATE CACHES/RESTART" then a dialog box will pop-up, Select "INVALIDATE CACHES/RESTART" button.

Android studio will automatically restart and rebuild the index.

or,

You can do the following things.

1. Restart logcat
2. Change from verbose to debug/error.
3. The last (Checked the regex ) Change the regex to show selected options only.
