@bluerfox15uht9 @themindfulteacher01v [This project](https://x.thunkable.com/copy/6bb974e4b558de93fffe2072c899e4c6) has a simple Bottom Tab Navigator. Running Android 9 on a Samsung S8, I experience no issues. Can either of you provide videos, project links or images of blocks to see if the problem lies there? ---

Thanks for your project link via dm @bluerfox15uht9. It appears you’ve created your own Bottom Tab Navigator, and are not using the [Bottom Tab Navigator component](https://docs.thunkable.com/bottom-tab-navigator). By using custom back buttons and a custom navigator, you are constantly opening new screens. This is very inefficient, and sounds like it _could_ be a leading factor to your app slowing down or crashing. Testing this on a Samsung S8 running Android 9, it does appear to work without flaws, despite your own experience. **May I recommend** that you remove the buttons at the bottom of your app on all screens that contain them (your diy Bottom Tab Navigator) and replace them with the [Bottom Tab Navigator component](https://docs.thunkable.com/bottom-tab-navigator). With your back buttons, this isn’t so much an issue, but if you wish to go one step further, consider checking out the [Stack Navigator component](https://docs.thunkable.com/stack-navigator). This will generate all your back buttons and let you seamlessly navigate between screens in any order, even repeating screens. This is a very powerful component. Where possible, it is always best practice to use standard navigation components. Let me know how you get on, Eoin. ---

i actually think i found a solution, if i put screens in different groups of navigators and make them invisible, it seems to negate this. for some reason… ---

I figured it out, if you put screens in different navigators, for whatever reason, it doesn’t freeze. You just have to set the navigators to invisible. I guess navigating between them resets things. 🤷🤦 ---

That took me way too long to figure out ---
