I tried the mobile page on my Android Samsung Galaxy S3. The first time everything worked great and I was able to add a fuel-up. The second time I tried, there is no period on the keypad, just numbers, so I can't enter number of gallons or price. I can enter numbers and go to prev and next fields. All other functions on the keypad are disabled. This means the mobile page is useless to me.
Sorry about that. This is a frustrating problem that we don't have control over. For some reason, the folks who control the version of the phone you have decided that a period isn't required for the numeric keypad. It doesn't make much sense. The numeric keypad is supposed to be different from the phone number keypad which doesn't require a period.
The frustrating thing is that this is limited to one or two versions of Android on Samsung. Most versions of Android have the period (and a comma) available on the numeric keypad.
You might look into sending fuel-ups via SMS. Or try using the fuel-up form on the full site. We don't specify that mobile devices should use a numeric keypad there.
This will set a cookie that tells Fuelly Mobile to use the standard keypad for entering numbers. So you'll have to shift around on the keypad to get to the numbers, but at least you'll have the option to use a decimal. This isn't an ideal solution, but there's just not much we can do from this side of things.
What's interesting about this is the actual decimal point is greyed out, and the little gear icon to configure the settings for the input is also greyed out... before it was not. I've been using the fuelly app for weeks and only last night did it not show the decimal point. Very strange.
