A flaw in the latest OTA update may be eating up your Asus ZenFone 2 storage space
If you own the high-ender on a bargain that is the Asus ZenFone 2, you might have experienced a particularly unpleasant issue which clogs the smartphone's storage. If that's the case, you're not alone. A number of Zenfone 2 owners have been hitting Reddit and Asus' forums with similar complaints and managed to trace the problem to a software bug that fills the device's internal storage with multiple gigabytes worth of pretty useless log files.
Until Asus does something, the problem can't be solved without rooting the device.Like most consumer electronics that run a software operating system, the Asus ZenFone 2 creates log files for various reasons, be it maintenance, diagnostics, or other forms of system book-keeping. These log files are supposed to be automatically trimmed so they don't eat up your storage space with obscure data. Apparently, something is preventing Asus' handset from fulfilling this duty, and what's worse, the sort of storage analyzing apps that usually help pinpoint the culprit in such situations are unable to tell you when things go awry. Log files are stored inside the system area partition of Android, which is not accessible without root privileges.
Unfortunately, it appears you can't do anything about the problem without rooting the device and voiding your warranty in the process. The issue is contained inside the data/logs/modemcrash folder, which grows massive with untrimmed logs in just a few days of use, eventually eating up almost all available storage. This folder cannot be emptied without root access.
Asus is yet to adress the complaints, but users believe the bug was introduced by a recent OTA update. Hopefully, it won't be too hard to fix whatever's wrong with the software in a timely manner.
