About +300 scans lost


I scanned about more 300 portals. I wanted to upload all of them during an [email protected] event. Neverthless when I start the upload, the animation of scan upload is running but nothing happens.

Device : Samsung S7

Ingress Version : 2.66.2-65dbe5ed

Android version : 8.0.0

Free space : ~ 9 GB

    Noticed this behavior already last December but not sure if NIA is investigating this:

    Maybe the bug report needs more up-votes.

    Anyway your scans are safe but a bug prevents sending them to NIA server.

  • Trying to upload 300 Portal Scans will take a very long time, even if you're on Wi-Fi. After starting the upload, can you clarify what you mean by, "nothing happens"? For example, if you start the Portal Scan upload and return to your Map Screen, do you see any of the +500 AP toast messages to show an indication of progress if you wait for a few minutes?

    Hereafter the video about "nothing happens". On Saturday i left the application to run for 1h. No scan was uploaded.

    No +500 AP toast in the map screen.

    Edit: Link to the video

    I found that it helped to install a connection speed app to display the upload/download speed in the taskbar, this way you can see if something is actually going through and happening. If nothing is uploading, it might be a firewall issue?

    300 scans is huge, I've been doing about 150 tops and although it's slow haven't seen any issues.

    I have had trouble with this since December 2020 (back log uploading multiple scan on WiFi) but today I also noticed that I can't even update a single scan anymore. It works sometimes and sometimes not.

    As for my case, I haven't seen anything and have not gotten any Ap or ticks for the portal scans. Sometimes the app crash after 10 mins of loading and sometimes after 30min - 1 hour. But it always crash.

  • I suffer from the same problem, too. When I acquire data of more than 200, go home and try upload in WIFI, only several files are completed, and tens of filing is completed, and it has stopped at the thing of which a reaction died after that and a different case. Though several first files were successful in upload every several seconds, even if it has passed for 5 minutes suddenly, nothing happens, and when it's being left just as it is, an application crashes. It's reluctant, but I have no choice but to carry out data clearance. I sacrificed hundreds of of data already.

    I, it's guessed, when the file damaged by some reasons has been generated, I think I try to upload the file, and the phenomenon I don't advance towards the front eternally has occurred.

    An acquaintance, in Android, like, when I encountered a phenomenon and the scan data was checked, a file of 1KB was found. When I eliminated this and challenged once again, upload resumed.

    The one even normal data has made wasteful by a cause of a damaged file is the current state.

    In the data whether you break if the data damaged during upload is confirmed, skips a damaged file, and by which it's the next whether you break if the data damaged during upload is confirmed, I move, specification improvement, please.

    I have same problem , did like 20-30 scans. Using Android, when I try too upload them with wifi at home the whole app crashes after a while (usually around the 5 minute mark). Sometimes when I scan I get a "1 MB" scan (looks like a red question mark). It it usually when I get one of those my whole uploading process wont progress.

  • I know my question is way off this topic, but what is the maximum number of portal scans one agent can hold and then upload successfully? 200 or 300? Does it also depend on the device one is using?

  • NaruwasherNaruwasher ✭✭✭✭

    When I first started scanning in March 2020, the maximum I held to upload later were about 70 scans. Ended up losing 17 of the 70 scans I did so I never used the "upload later" option again. I would suspect it also depends on the device and free storage on that device. Scans can accumulate in size real quick.

  • I feel bad that you lost 17 of those scans which you captured. Isn't there any other way to retrieve those lost scans? Niantic should at least have a back-up/retrieval system for those scans that agents like yourself worked hard for. Thank you for the valuable information.

    Any update from the back stage @NianticBrian?

  • BlaumutBlaumut ✭✭✭

    Hello @NianticBrian, any update? Thanks

  • @Blaumut I'm not sure what corrupted a given Portal Scan, but we're investigating ways to provide more granularity with upload management of Portal Scans versus the current bulk upload. This should help address the original issue because when a Portal Scan is corrupted, as mentioned above, it can block subsequent uploads of other Portal Scans in the queue.

    Thanks for your answer. Should i delete all the data or do you suggest to delete all and scan again?

  • Hulk32Hulk32 ✭✭✭

    Available portal nominations and portal scan slots in a settings section would be a nice addiction on top of that. Right now, you have to actually start the process of nominating a new portal or scanning, which needs a portal in range, to get these numbers. Having them at a glance would help us to plan travels to populate the portal network from home. Thanks!

    And again more scans lost. About 90 scans done, only 5 uploaded. 1 hour connected on wifi without any update.

    Version 2.701-3e2bOb3d Samsung Galaxy 7.

    I will delete all the data again.

    @NianticBrian could you push a reset of the number of scans available ? Or should I open a ticket every time ?
