Chrome Version: ToT
OS: Android 7.0, Samsung's build number NRD90M.G930FXXU1DQL7

What steps will reproduce the problem?
(1) Build debug version of ChromePublic.apk per the instructions here:
https://chromium.googlesource.com/chromium/src/+/master/docs/android_build_instructions.md

with the following GN args:
-----
target_os = "android"
# target_cpu = "arm64"  # (default)
target_cpu = "arm"
is_debug = true  # (default)
ffmpeg_branding = "Chrome"
proprietary_codecs = true

# Other args you may want to set:
is_component_build = true
# is_clang = true
strip_absolute_paths_from_debug_symbols = true
symbol_level = 1  # Faster build with fewer symbols. -g1 rather than -g2
# enable_incremental_javac = true  # Much faster; experimental

use_goma = true
goma_dir = "/usr/local/google/home/kbr/goma"
-----
(2) ./build/android/adb_install_apk.py out/AndroidDebug/apks/ChromePublic.apk
(3) Run Chromium

Note that developer mode is enabled on the phone and apps from unknown sources are allowed.

What is the expected result?

Expect Chromium to run.


What happens instead?

Chromium crashes after clicking "Accept and Continue". adb logcat reports the following, which I assume is the reason for the failure:

Is this a known problem? I can't make progress on Issue 839769 without being able to rebuild the browser for this device.
