There was a really big problem plaguing my phone the past weeks. For some reason, even if the apps installed weren’t taking up much space (a couple hundred MB at max), my device memory was running low (1.7GB out of 1.97GB). Here’s how I instantly cleaned 700MB off of it:
After some time of using Clean Master (I love this app btw) and not reclaiming any device memory from my phone, I decided to finally Google the problem which led me to this post on Android Central forums. The guy who posted this saved my life!
What he said was to dial #9900# (as a USSD/MMI code) and select the second option which says “Delete dumpstate/logcat”.
I tried dialing the code but it just kept saying “Connection problem or invalid MMI code.” After some moment of aimless googling I came across the code *#9900# so I tried it and voila, it works!
I checked my phone after deleting the dumpstate/logcat and it went down to 1GB from 1.7GB. Magic :O
How To Fix This Issue
- Dial #9900# or *#9900# (one or the other should work). The code is preferably dialed on the native dialer.
- When the menu pops up, choose the second option which says “Delete dumpstate/logcat” and then exit the menu.
- You may reboot your phone (but then it might be unnecessary). I did it anyway for good measure.
This was done on a Samsung GT-I9100 Galaxy SII phone running stock Samsung Android v4.1.2 (Jellybean). I can’t guarantee it will work on other phones, but maybe it will :)
