Recently got a new phone, a samsung A12. Ran 10 miles at the weekend and it looked okay but some of my paces were definitely wrong. I've never come close to a 6:36 mile!
Today ran 4 and its dropped 1.2 miles and my pace is totally wrong (45s / mile)
My old iphone 7 never had any issues.
Any idea? Its pretty annoying.
