Emailed and air dropped files appear to have been corrupted when the user clicks send before the project is fully packaged.
On XO Tablet (Android 4.3):
Further comments from original issue:
This might be due to the slow processor on this particular tablet, but that might be indicative of many Android 4.2 / 4.3 tablets, so we should look at a way of speeding this up. Note that rotation is working smoothly on smaller shapes, but not on complex shapes like Scratch cat.
Here's an idea for how we can fix this, and improve performance in the process. Instead of drawing the SVG each frame, draw the SVG to a temporary canvas and then rotate the canvas. When the rotation is complete, update the image and destroy the working canvas.
I've confirmed with debug statements that the reason it is not responding is that mouseMove is not being fired. I'm tracking down the code that's preventing mouseMove from being fired. Looks like it's Layer.findGroup().
It's not directly caused by Layer.findGroup(). Instead, it looks like the more objects that are selected, the longer it takes the mouse events to process, and eventually the browser gives up sending the mouseMove events. This only seems to happen on Android 4.2 and 4.3 tablets, and I haven't found a good fix yet.
However, this is a workaround - to rotate, simply start dragging, let go, and tap in the final spot you want it to rotate. Not as good as interactive rotation, but better than not rotating at all.
Galaxy Tab 2 (7-inch) running 4.2 had the same issue. simple shapes could rotate, more complex ones had problems - the workaround did "solve" it.
We noticed the same sort of issues with using the camera. Tapping a simple shape the camera would come up relatively quickly. (The snake worked for example) But anything complex it would take a really long time, or never come up.

Blocks rendered incorrectly in the PBS Kids version (1.1) on Cyanogenmod 12. See attached screenshots. We were not able to reproduce on Cyanogenmod 11 and do not have access to CM12.
We need help investigating whether this is common to all versions, or unique to the PBS version.

A common request: We could provide a way to import characters and backgrounds from the device's photo reel. This is a bit of work because we need to figure out how to handle non-paint editor/raster assets.

<uses-permission android:name="android.permission.RECORD_AUDIO"/>
implies microphone is required.
We need an explicit uses-feature that makes the microphone optional.
Sometimes sounds in the JSON for a project are null. This was causing the earlier 'Error-reload' problem. The app now ignores null sounds and still opens the project, but obviously any sound that is null is missing. We need to discover why the sounds are not getting saved in the first place. We have not been able to consistently reproduce this problem.

When attempting to take a second picture, there is a display artifact from the previous picture taken for the same shape. Seems to be a mask issue. This doesn't happen on later tablets.
Consider this picture of a test image, followed by a picture of an orange, in an oval-like shape.
Additional comments from original issue:
I looked at this for several hours. It appears that both Android 4.2 and Android 5.x are generating the same .svg from the camera, but when it comes to programmatically drawing the SVG to the canvas, some of the cropping is not working correctly in Android 4.2.
I'm not 100% sure of this, but this could be a fundamental limitation of the SVG engine in Android 4.2. There have been several complaints by the community about missing features, etc. I'm thinking this might not be an easy one to fix and we don't want to hold up the release for this one because it is somewhat rarely encountered and easily worked around. This would only happen if someone takes more than one picture in the same Sprite.

when it finishes sending, go back to project.
blue bubble says saving in the upper left, becomes waiting and never disappears.
Happens about half the time on the asus nexus 7, less often on samsung 10.
We should be cropping the webcam images to only the portion visible so as not to store any information the user cannot see.

This may be related to the problems with some tablets not knowing that ScratchJr should be associated with the sjr extension.
The attachment used to have the ScratchJr icon instead of plain white box. Definitely happens on iOS, would need to confirm on android.
The speech bubble in normal mode looks right, but in full-screen mode there is extra space in the bubble.

Color background for the blocks guide headers are fixed width. They just barely fit for Spanish (END BLOCKS looks bad), it's likely that some other language will not fit in the width.
Language can be switched by setting the locale in the Android settings. Can't switch the language in the application.

Scrolling to the bottom of the About ScratchJr or Blocks description pages, then switching to a different page (e.g., Home or Settings) doesn't reset the scroll position. On the new (shorter) page nothing is visible until you scroll up.
@tmickel commented:
Scroll position is being stored in file system ("homescroll.sjr")
It seems that the scroll position should be reset when the projects are drawn. But for some reason it appears the value from the in-app help is getting carried over (and then saved into homescroll)

Blocks other than the start and end blocks become invisible, but are still connected (visible when moving the stack), and run when activated.
A school in Dublin has been having this problem:
Tablet is Hannspree SN1AT74/HANNSpad.
Shorter set of steps to reproduce: Start new project. Drag 'green flag' start block into scripts area. Drag 'move 1 step right' block, attaching to 'green flag' block. Drag the 'script canvas' side to side. (I.e., press and drag somewhere in the scripts space where no block is.) The 'move right' block becomes invisible.
Here's a video of the problem:

pull out a couple of blocks and position them so that they're overlapping.
pull out another block and position it to connect to the block that is behind the other. The block connects but stays in front while the block it's connected to stays behind. Probably it should be as if the whole stack was moved and it all comes to the front. In the example below the green flag is on top of the pink blocks, but connected to the blue ones behind.

It seems to be a combination of length (short scripts are always draggable), and whether or not it has overflowed the script pane. But when it happens you can't drag the whole script around. You can still select something in the middle and drag the end off.

This might require some design discussion - since it's works similarly in iOS.

Currently new project names are generated by reading the existing projects' in the lobby's DOM. The method for getting "Project 1", "Project 2", etc. involve string operations - not nice for localization. I've temporarily put in a "project prefix" (Project, Proyecto, etc.) but it would be good to rethink this entirely for a more "localizable" way

The Spanish for 'Share by email' doesn't really fit on the current button. It should be responsive to the actual text for future translations.
If you upload a project to ScratchJr from an email, at first it doesn't show up in the My Projects list, but if you wait a few seconds or you go to another project or create a new project and then return to the My Projects list, the project will be there (works, scripts are there, etc.).
Steps to repro:
You can repeat the above steps, but with ScratchJr closed initially (and let it get opened automatically when you choose the "Copy to ScratchJr" app), and the new project should show up almost immediately/ immediately once Scratch loads and you click on the Home icon. So, this seems to be a performance issue when the ScratchJr app is already running when you download the file from the email.
People are confused about which language is actually selected. Switching the color of the button is not distinct enough, and the fact that the language prompt changes language is too subtle.
It needs something more to designate the currently selected language.
Hello ScratchJr Team,
I found the problem related to Japanese.
When I shared the project with email, an error occurred.
The error occurred when I tapped the attached project file.
I attach snapshots and forward a mail with the problem.
The project named in Japanese.
I also noticed that the file name changed to null.
In spite of error occurs, the project has been able to share without a problem.
I can share the project but I hope to resolve this problem.
Best Regards,
Junko

Currently we're using UIWebview. WKWebview is supported on iOS 8+, which according to our analytics is at least 80% of iOS users. Switching to WKWebview will provide better performance, a much nicer JS-native interface, and hopefully less bugs.

@tmickel commented:
Sharing code was originally written to exist only in JavaScript. The .zip is assembled in memory. For projects with large amounts of custom sounds/photographs, this can cause a lot of memory to be used - sometimes the tablet is slow or crashes. Moving this to native code would allow the zip to be assembled on-disk and be done much faster.
Some research:
https://github.com/ZipArchive/ZipArchive would probably make a nice replacement for JSZip on iOS.
Android appears to have a native SDK for zip/unzip, example here: https://stackoverflow.com/questions/7485114/how-to-zip-and-unzip-the-files - It might require we use the "external storage" permission for the unzip process, not sure...
I think the nicest strategy here will be to maintain the JS code for 90% of the logic of zipping the project. We should provide a native/on-disk replacement for JSZip only...
The JS code for collecting and sorting assets is relatively solid at this point, the only problem is the memory issue...

If you draw a shape, then exit the paint editor the shape outline does not get resized.
Click on another sprite, then back to the first, and the outline is resized.
It doesn't happen on predefined characters, or if you start with a predefined character.
The screen shots are of the editor after exiting the paint editor, and then after clicking on a different sprite.

Open the paint editor and create a background. Open the background library again and select the user created background. It should have the name 'background', It always shows the name of the last selected background. So if you select one of the named backgrounds, then go back to a user created one, it will still show the name of the previous background.
