Failing at reporting Android bugs


Android logo.

I try to write good bug reports, I really do. I fill out templates when asked. I try to include reproducible proof of the bug. I'll even give a screenshot or screen recording to prove I'm not making things up. If I'm familiar enough with the programming language, I'll also attempt to say roughly where…

What's the window size of a background tab?


The Outer window size is zero by zero.

Whenever I open Twitter in a new tab on my phone, the page layout looks weird for a few seconds. It starts out looking like the desktop view and then, after a few seconds, it snaps back to the mobile view. What's causing this? Try opening this link to a window size detector in a…

How do you raise a software bug with a book publisher?


HTML code - a span wraps the first letter of a word.

Recently, I bought an eBook which has a bug. I'd like to explain what the bug is, why it is a problem, and how I'm trying to get it corrected. Amazon sells eBooks in KF8 format. That is an ePub with some proprietary extras. ePub is a standard based off HTML5. You can read the…

Whose bug is it anyway?


A 404 error message on a website.

My mobile network provider sent me this message: I clicked on the link, and got this error message from their website: The error is caused by the trailing full-stop.

Raw HTML in the middle of an email.

Another day, another Gmail bug which won't get fixed. The original Android phone - HTC Dream - had 192MB of RAM. The latest Android phones tend to have 6GB. A 32 times increase in a decade. Laptops have also leapt forwards in speed and memory. Sadly, no one on the Gmail team has noticed. It's…

Amazon Prime Video's weird Unicode problems


Description with an error in it.

It's 2019 and high-tech devices are still plagued by text encoding bugs. I recently bought the new 4K Amazon Fire Stick. It's a little Android dongle which plays videos. It's neat - but quite often displays weird text errors. Take the kids' TV show House of Anubis, the Fire displays the description like this: Looking…

Virgin Media don't understand Unicode


HTML code from Virgin.

More adventures with Unicode. I logged in to my Virgin Media account to see when my promotional discount would end. Here's what their billing PDF said. Let'S Ignore The Weird Capitalisation Virgin'S System Uses. What's that  doing there? Their website says: No  symbol, but also no £ sign. Ah, but let's look at…
