Network utilization on Panasonic P55 exceeded 1024 KB, you might want to consider bringing it down

There is high probability of identifying risks running the apps with conditions

120 apps having similar CPU load have low Chhi Scores

Testability: Providing login / sign-up details could very well improve depth of bot clicks

Caching: Use LruCache for data caching to optimize memory usage

The app has crashed on few device(s)! View details

Coverage: Android version coverage for reports will range between 5.1.1 to 7.1.2

Upload APKs with and without 3rd Party SDKs to monitor and optimize the impact of app performance

Network utilization on Lava Iris X8 exceeded 1024 KB, you might want to consider bringing it down

Do not initialize objects that aren't necessary during launch times. Moving to singleton pattern helps

Total Network data consumed was 1176.78KB in Lava Iris X8 , This indicates the app will take 10-15 seconds on 2G network and 8-9 seconds on 3G network to load! View details

Fix Oncreate() if the launch time is exceeding more than 3.2 secs. Try deflating views and layouts to optimize.
