Hi, Thanks for that hint Jacque will certainly have a look at that. Panos - we have 4 Iphone pluses and they are all set to standard - all worked fine before. But I checked mine and another just in case an IOS update changed it - nope both still standard. Thanks though - every suggestion

Seems to me if you are tracking linear movement, you need to average the trending values, say the last 5 or 10 reads, against a time base, and reject the ones outside an acceptable tolerance. You may reject some good data here and there, but something grossly outside tolerance should be pretty

Hi Graham Are you checking the horizontal accuracy of each reading? (It's part of the array of data with your lat-longs, as well as speed, etc - though not on every phone). If not, try that and see if the anomalous readings are hugely out. From my experience, that's normally the case. If so,

Thank you Matthias, I wasn’t aware of that ability to open the file and read its contents straight from the disk. A quick experiment looks positive - no hanging and fast access - so I just need to work on the loop. Much obliged. Best, Keith > On 3 Nov 2020, at 13:37, matthias rebbe via

Couldn't you read the file partially you would open the file for read open file tFile for read then in a repeat loop you could read e.g. 1 lines and process the data read from file tFile for 1 lines Just a thought. - Matthias Rebbe Life Is Too Short For Boring Code

Hello Lagi, In the iPhone 8 Plus device, could you check in Settings -> Display and Brightness and then scroll down and in the "Display Zoom" section, does it say "Standard" or "Zoomed" ? If it says Zoomed, then the stack will scale as if it was on an iPhone 8. Changing this to Standard will
