Why is my phone saying "memory dangerously low" after hard reset?

[Android Central Question]

My Samsung Galaxy S7 stopped showing voicemail notifications and would not ring all the time. I took phone up to MetroPCS and they couldn't figure it out then told me I needed to get a new phone.

I then got with Samsung Tech support and they had me do a soft reset and put phone in safe mode to see if the issue was coming from 3rd party app. Those steps did not work so they told me to take phone into Samsung store to see if they can help.

Instead of doing that, I took my Memory card out and performed a hard reset. I then reinserted memory card and the hard reset solved the Voicemail Notification issue, but now I keep getting warning saying "memory dangerously low" - 31.2GB/32GB. I noticed it copied my memos multiple times (each recording was showing 10 copies) so I deleted all Samsung Memo Recordings which did nothing for the memory. Before the reset - my internal memory was around 20GB/32GB. I have uninstalled all my apps so only the pre-installed apps are on it, which lowered it from 31.7 to 31.2GB. Why would doing a reset mess up the memory and how can I fix this?

When I go into Device Maintenance and try to look at internal storage, there are several folders but there is nothing in most of them. Please help! I have been out of work since October so I do not have the money to get a new phone.

THANK YOU IN ADVANCE

Welcome to Android Central! When you say you did a hard reset, do you mean a factory data reset? Or did you just power the phone completely off, and the power it back on again?

When you do a "hard reset" - meaning a factory reset - all your installed apps are removed, and you have to set the phone up again. Since you had to remove your installed apps after you did what you call a hard reset, you didn't really do a hard reset.

If you do a factory reset, you should be back to the state the phone was in when you got it. (But I'd try to install an app like App Backup & Restore or Helium and back up all the apps (and, with Helium, you can back up the data too). Then you can reinstall whatever apps you want without waiting hours for them to download.
