No matter which trip meter is being used they all display the same information so it's pointless to have trip meter A, B, and C.<\/h3>When I\u00a0built the trip meters into the app I started with just one, because at the time I thought that’s all I’d need. Not long\u00a0after I started testing it I realised that I could see how long the first leg of my journey was but unless I made a not somewhere I couldn’t see how long the return leg was, just the total distance, when I\u00a0got back.<\/p>\n
So then I decided to build in a couple more trip meters which could all be reset independently, giving me the ability to record the distance for three legs of my journey (although in my case I’m really only interested in there and back).<\/p>\n
You can reset the currently displayed trip meter by long-pressing it. The other trip meters will be unaffected.<\/p>\n
View<\/a><\/p><\/div><\/div>Help, I'm getting a \u201cScreen overlay detected\u201d dialog!<\/h3>I believe that\u00a0this popup is not actually caused by DigiHUD, but rather the operating system has detected that an app on the device has created an overlay that is running when a\u00a0Permission\u00a0screen is being shown.<\/p>\n
<\/p>\n
Permissions screens are very powerful, in\u00a0that they allow third-party apps to control core functionality of the phone, read\/modify\/delete your sensitive information and even cost you money. Google want to ensure that no rogue apps can\u00a0‘interfere’ with your Permission choices by creating a screen overlay and using a technique known as “Clickjacking” (here’s a great Android-specific example: https:\/\/www.skycure.com\/blog\/accessibility-clickjacking\/<\/a>) to get you to unknowingly grant Permissions.\u00a0This is potentially a very serious risk to device security.<\/p>\nSo, any app running that is creating an overlay when a Permission screen is shown will cause this popup to appear, that’s if your device is using the new Permission system introduced in Android 6 Marshmallow.<\/p>\n

Screen Overlay Detected dialog created by Android<\/p><\/div>\n
<\/p>\n
For any app that’s requesting Permissions, not just DigiHUD, just ensure that no apps are running that create overlays (apps like ‘Lux’ or ‘Twilight’ that create coloured screen filters or control screen brightness) when the Permission is being requested<\/strong>. Once that’s been done then these apps can be turned back on.<\/p>\n <\/p>\n
EDIT: I’ve found that in some cases the Important Information screen that appears when the app is installed for the first time was causing the warning to appear. This has been addressed and a new version of the free app has just been released.<\/p>\n

In some cases, possibly after a version upgrade, it may be necessary to clear the app data (which will clear all recorded values). I always try a device reboot first though. If this doesn’t help then uninstall and reinstall the app. On some newer versions of Android it’s a good idea\u00a0to choose ‘Uninstall for all users’ from the menu if available.<\/p>\n

It may be useful to compare the speed against other GPS apps in the same environment, to see if they too can\u2019t get a reading. One I find very useful is \u2018GPS Test\u2019 by Chartcross<\/a>.<\/p>\nHere’s a post from the Internet with more information on troubleshooting Android GPS issues:
\nhttps:\/\/www.androidpit.com\/how-to-improve-your-gps-signal-on-your-android<\/a>\u00a0(opens in a new window\/tab).<\/p>\nBy opening the app in Window mode it allows the speed to be seen on top of other apps ( for example GPS Test) to more easily compare the speed readings simultaneously.<\/p>\n
View<\/a><\/p><\/div><\/div>The speed is flashing and doesn't update. Help!<\/h3>This is probably\u00a0because the app is ‘paused’. Tap\u00a0the PAUSE RESET icon to resume.<\/p>\n

There are three screen modes (ignoring Window mode for the purposes of this FAQ):<\/p>\n
\n- Fullscreen mode – Shows lots of useful information which can be shown\/hidden in Settings<\/li>\n
- Map mode – half speed, half simple Google Map. No navigation or anything fancy, apart from traffic. (Pro version only)<\/li>\n
- Lite mode – only show your speed in nice big numbers<\/li>\n<\/ul>\n
Swipe the speed<\/strong> left or right to change modes. The screens loop, so whichever way you swipe you’ll end up at the same mode after a couple of swipes.<\/p>\nView<\/a><\/p><\/div><\/div>The speed is different to my car speed. Why?<\/h3>See this answer<\/a>.<\/p>\nIf you\u2019d rather show the speed matching the vehicle\u00a0speed then the Pro version allows a percentage offset to be applied to the speed.<\/p>\n
View<\/a><\/p><\/div><\/div>The speed is always behind my car speed when accelerating or decelerating.<\/h3>Two GPS positions need to\u00a0be used\u00a0to calculate speed and then the calculated information can be rendered on the device.

The app processes the GPS data as soon as it is received but without clever predictive algorithms the delay is as small as I can make it.<\/p>\n
I’ve recently been using an external Bluetooth GPS receiver that can send updates at up to 10 times per second – about 10 times faster than the receiver built in to phones and tablets. I’ve found that the lag is eliminated with this device and DigiHUD works perfectly fine\u00a0with it. I’ve tested it with three devices – HTC wildfire (Android 2.3), Samsung Galaxy S3 (Android 4.4) and an LG G3 (Android 5.0) and each one has performed great with no issues.<\/p>\n
