• Type of device; One Plus Nord N200 5G
• Whether a carrier/network device, or SIM-free; Fiz
• Whether bought new or used; Bought new last december
• Whether the device may have incurred damage, such as from impact or water; Nope shouldn't have any damage
• What version of the OS; Android 11
• Whether the trouble is on Wifi, mobile data, or both; I'm not totally sure
• The source from which any troublesome apps or software were downloaded; all apps were downloaded in the google play store
• What you’ve already tried to fix the problem; We did multiple factory reset, we sent it to oneplus twice and nothing is fixed. System storage just gradually grow until it takes all the free space. At that point if you delete an app it will grow to take the space you just freed. The bug can appear rapidly (24 to 48h after the reset) or it can take up to a few weeks. We also tried to unlock the phone and test it with a different sim. the problem didn't appear but 3 days after we lock the phone back and set it with the owner sim card the bug reappeared : system storage went from 13gb to 23gb to 25gb and to 28gb in the same day. I tried to make it grow again since and I can't figure it out.
• What message appears if you try to do something, but are unable; If we let it take all space it will say : stockage almost full, some system fonctionnality may close. Free some space to use messenger and apps will start closing or not opening or crash.
• What you were doing before the problem occurred; I wish I knew, I'm trying everything to trigger it c_c it just does it but I can't figure out why.
• Whether you are using an SD card; At first yes but then we tried without it and it didn't change anything.
• Whether the device software has been modified or customised; Nope we tried to keep it as simple as they are
• Whether there were recent repairs; So like I said we sent it twice de Oneplus repair center. the first time they changed the motherboard the second time they only did a customer system update. they then asked me to make logs and a post on their community which have plenty of cases with the same issue but no anwser. I'm getting desseperate please help. (link of the oneplus post with pictures : https://forums.oneplus.com/threads/storage-taking-up-all-free-space.1575850/)
