Here is a list of some know bugs you may come across. Our aim is to keep this list very small!
Bug in survey apps – cannot take a new photo…
The Android system has an inbuilt set of security permissions and a strict rules for controlling them (read more about permissions). The OTISS survey apps follow the Android guidelines and will ask your permission to allow the app to use the camera – typically you only have to do this once.
Normally this works fine, but occasionally the Android system seems to withdraw the permission or never gets around to asking you. In this case the Camera icon is disabled and the app cannot use the camera until you do the following.
- On your phone/tablet, open the main Settings app .
- Tap Apps or Application Manager (depending on your device, this may look different).
- Tap the app you want to update.
- Tap Permissions.
- Next to a permission you want to turn on, move the switch to the right until it turns green. If you want to turn a permission off, move the switch to the left until it turns gray.
Bug in survey apps – Survey Form does not always appear…
This issue is seen very rarely, and is only an issue on some manufacturers phones/tablets and only when running certain releases of the Android software. It usually stops happening when the manufacturer releases a software upgrade.
When using the maps to survey a site and you try to Add or Edit a tree/item, the survey form should appear. But on some devices the survey form does not always appear, the map disappears and you are returned to the list of surveys. Trying the same action again often does work for a few times, but then it fails again – it is all a bit random!
This behaviour is due to a bug in a combination of the Android operating software and the device’s hardware.
- Go to the Survey App’s Main Menu.
- Click on the Settings icon at the top of the page.
- Scroll down and find the setting for “Enable hardware acceleration for map“.
- Untick this feature and press the back button.
- All done!
- Start surveying again and everything should work correctly. There may be a ‘very’ small slowness when you pan and zoom around the maps, but it is not very noticable.
If you are still seeing the problem after disabling the hardware acceleration above, then please contact our support staff.
Bug in survey apps – Download Offline Maps…
This issue is only seen in older Android 4.x devices and in low-spec/cheap tablets.
While downloading a large set of map tiles, the app just stops doing the download and returns to the Downloaded Surveys menu. Whereas, it should complete the download and display a message beneath the map to say the download is complete.
This behaviour is due low memeory or low performance of the older Android operating software – we think!
When requesting a download, simply zoom in a step further and download the required area in several smaller areas.
