Android storage problem With a phone of 1 GB internal memory, I am able to install apps for 700 MB only. More than that I get the insufficient memory alert. 

Storage shows:


Total space 0.98

Available 71.49
Apps 601
Cache 1.88


Another phone of the same model is able to able to install apps for the entire 1GB.

Phone runs on Android version 4.2.x. Default write disk is external SD card. 

Thanks in advance. Screenshots below:

In most android devices this insufficient storage issue is to do with Log files being dumped in the /data/log folder. The log files appear to be the logdump for the gsm radio, and can take up a lot of space over time (Gigabytes even).

Most phones without root have a workaround to delete the logs by dialing *#9900# from the phones dial pad. If your phone supports this then the moment you finish entering the 2nd hash, a menu will open up (point is: if it doesnt support nothing happens; pressing the call button wont help). In the menu that opens, select "delete dumpstate/logcat". That will free up all the space occupied by those logs.

Do let me know if any of you with a A116 is lucky to have this workaround. I have an A116 with the same problem, and am not able to find a solution.
