Designer Tools Customer Insights

1. 😉please update your system, I'm using Android 12 and it doesn't work anymore, at first it still worked after a few days it couldn't be used anymore and the phone screen couldn't be pushed if the app was runningi just downloaded the app, i like it really., the reason why i only give 2 stars is that, i don't like it's appearance all over my phone, i can't clearly read my FB wall, it is all over the phone 🤣🤣🤣..i hope they'll put a settings in this that would only allow particular apps to display overCan you please fix it for xiaomi mi note 10 lite its not working, when i try to used the overlay for may screen i can't used any apps i can't click on anything its like frozen, its good apps for may other phone!There is a problem on Android 12 when grid overlay is tuned on which is preventing interaction with the rest of the system.

2. Now only if the colour picker didn't have a grid, I could use it to magnify tiny screen text.🤣Your app is Good great job but can you fix the portrait or landscape mode when your in the camera mode it will appear i know that you have to manually turn it off but please in your next update can you customize the following built in apk that we use? So when we open an another apk it will not appear anymore.It will be a great help 🙂.Ok this app is great I can use it as virtual controller design in emulators, and a background in apps like Google and facebook, but I have a suggestion, could you make this app appear in certain apps only? Not like it's everywhere, well I will very much appreciate it.

3. So if you can provide option to remove it from apps background it would really good.It's nice that I can have my favorite photo overlay on the screen and has a separate photo option for landscape, but photo's not switching for portrait to landscape fast, and vice-versa.

4. but there is one problem the background image is seen when we open other apps also e.g. like if we use Instagram, Facebook and other apps the image is seen in the background and it becomes difficult to read the stories and feeds of Instagram and Facebook.

5. And when I go back to portrait mode, the landscape photo is still on screen, not the assigned portrait photo.

6. And when the assigned landscape photo is shown, it only shows on the middle lower part of the screen.

7. It's super useful and I would recommend it to any Android developer who is serious about UI work.I am using the mock-up overlay function as a system wide wallpaper overlay.

8. When I'm in landscape mode, the portait photo is still on the background.

9. I hope this bug be fixed.I downloaded it looking for a key line overlay app and was pleasantly surprised to find way more useful functionality.

10. Other features are working properly.

11. The app is superb.
