Why is my phone counting steps I overnight while I sleep?

[sarahbreana]

I have a samsung s22 and use the samsung health app to check on my daily step count. I do not own a fitness watch and my phone sits motionless on my bedside table at night. Suddenly it's started to count me taking 30k steps between midnight and 4am while I'm asleep. What's going on? Is this a known issue? Should I invest in another form of step counting if this is an ongoing bug? I need something accurate to present to my physician. Thank you in advance for you help!

I know for a fact I'm not because I need a cane to walk atm and would wake up having fallen from lsck of balance

Maybe download another step counter app and see if they match up.

@sarahbreana: Is this issue only occurring when you place your phone on your bedside table, or have you noticed if the step count goes up while the phone is idle in other locations? 

As a troubleshooting step, you may wish to head to Settings > Battery > Background usage limits > Deep sleeping apps > Tap the '+' in the top right corner > Samsung Health > Add. This will restrict the apps background activity, however please note that you will be required to manually open Samsung Health when you do want to track your step count.

I just woke up to the same situation. Says I have 24,000 steps, which is bogus.

Same thing just happened to me right now. I just woke up and I was asleep from 5am to 11am. Went to Samsung health and it says I have 7k steps?? Last time I checked, IT EVEN SAYS LAST SYNCED 3AM( cuz that's when I came home) I had 1.200 steps. Now the app started measuring from 8.30am to 9.30am??? I was asleep , had my phone in my counter and with approximately 27%. My guess is maybe I have connected my Samsung health with my mum's one ( I used to own the s10+ when it came out and gave it to my mom with my account maybe?). Other than that...your guess is good as mine.
