I had created a learning app and is fully working but there is something that i dont expect.
After downloading by many users they had told me that app is hanging and crashing in their mobiles with have 3GB+ G4 GB even.
But in my mobile (6GB+64GB) Mi K20 there is no such problems.
What is this problem now and how will it be solved. Please help me. You can download app from here : https://play.google.com/store/apps/details?id=com.csopedia.cs
