Sony Ericsson Yendo - often considered the worst SE phone
The Yendo, released in 2010, was a budget touchscreen feature phone which was actually designed by an ODM company (many sources say it's Sagem, but it could also be Arima).
It was so slow that it even made Eldar Murtazin of mobile-review want to throw it at a wall. He said he hasn't seen such a low-quality phone in several years.
While playing around with this phone, I found out that you can easily access the Java VM's internal system files using any J2ME file manager app.
