[bugreport] App periodically hangs when there are a lot of images

Having captured a larger number of images, app periodically hangs.
The effect seems to visibly appear somewhere around 7000 images.
App is slow to start up. Sometimes, when stopped and then resuming to move, it won’t take any images for a while, and does not respond to controls.
Sometimes this brief hang happens when displaying and hiding the map during the capture.

Slowness seems to depend on the number of already captured images.

Hey @Richlv, thanks for reporting bugs. Please, could you report bugs to support@mapillary.com? Thanks.

@asturksever, thank you so much for checking on this. Emailing things is a blackhole, no clue what happens to those emails - but will send there a collection of bugreports that are still relevant.

Still happens in the latest version.

I can concur with the app hanging. I’ll send an email as well. Usually happens over 3000 images I’ve found. I usually try to hit the stop button and start again somewhere around 1000-1200 images that way I can upload in chunks.

For me, the number of images in the current sequence does not seem to have a big impact - the total number of the images does.
The brief hang sometimes happens right when I start a new sequence.

Yep me too, I’ve been having this issue for years now whenever I use my phone to take pictures of more than 10000 in total. The performance will start to degrade the more pictures I have until the camera view in the app just won’t show up (black screen) as well as timing out when I try to add exif or upload straight from my phone.

Just a note that in older versions of the app this was fine - I was able to capture 55K images on the same phone without such hangs.
