As we all know, Gerrit doesn't have the best interface, but even more so, it's not very mobile friendly. There is however mGerrit [1] for Android which does a nice job.
Also, we're not in the list of default "supported" Gerrit instannces (yes, I know WikiMedia is in CamelCase, this is already reported and fixed upstream).
If you've any issues with the software emailing the developer directly is quite good at yielding responses.
