System partitions are divided into systems and data directories, which can be obtained by root and installed in the re browser. The size of these two partitions is fixed in ROM, that is, system (only used to install the application), a7272+ General 200mb;dtat (used to install the user's own application), a7272+ generally 220MB. So removing the system's own application only makes system partition free space larger, but it cannot be used as the data directory. This is like our computer's C disk and D disk, because the System Setup installation application can only be installed in D, so the C disk is no use; available memory is the data directory determines how many applications we can install, the obvious problem is in data.
The following through their own test, the oil can be assured.
First the phone wants root permission,
1, with the "RE manager" Mount right after the phone to open the root directory data/local/tmp Delete this folder under the APK file. Android Phone installer, first of all, copy the APK program to the TMP folder to install, after the successful installation will be automatically deleted, if the failure of the APK program will be retained. So if you look closely at the APK program in the TMP folder, you will find that the name is the same as the program name you failed to install, and the Data/local/tmp folder is normally empty.
2, if the TMP file is empty, use the "Re manager" Mount permissions after opening the phone root, delete the root directory of mobile phone data/core/core.xxxx file (xxxx for four digits), here Note: Delete this file creation time and you install software failure time coincide, The file size matches the number of your phone's memory loss (typically a larger file inside, with dozens of M). Using the "RE manager" operation is more intuitive--not only can the notice bar show the current mobile phone has been used, available memory size, you can also directly display the exact time and file size of the file you want to delete, making it easier to find the file you want to delete, and the ES file browser needs to view the file attributes to determine In fact, ES file browser is not compatible with many models, such as using ES file browser to view the root directory of a mobile phone data file properties, the display of the file is 0 bytes, under the 0 files, which is clearly wrong, easy to make people wrong judgments.
Oil to ask: Remove Core.xxxx file or delete the wrong core.xxxx mobile phone will not change bricks. Let's take a look at the role of the core.xxxx file, core.xxxx files are mainly recorded mobile phone installation application data, the role is the mobile phone through the data cable to the PC side, through the software on the PC (such as: Pea pod, 91 assistants) when the mobile phone to install the application data, You can make your PC software (such as pea pods, 91 assistants) display the number of mobile phone installation applications, the list of program information, so that on the PC through the software to the mobile phone applications to view, delete, upgrade and other operations. Without core.xxxx this file, PC software can not recognize the mobile phone installation application situation, some friends will ask: no core.xxxx My computer is not unable to the mobile application to view, delete, upgrade and other operations. , in fact, this worry is completely unnecessary, with 91 of assistants, for example, when the phone needs to connect the computer software on the mobile phone application operation, you can turn on the Computer 91 Assistant Select Mobile application Options, and then click 91 Assistant Refresh button, a few minutes later in the phone root directory data/core/ A properly complete core.xxxx is automatically generated under the folder so that the 91 Assistant can read the application information on the phone completely. Understand this, as long as you do not delete the system from the Core.xxxx file (data/core/creation time of the earliest core.xxxx file), Other core.xxxx files can be deleted, if you do not feel safe, then you can delete the core.xxxx mobile to the phone's SD card backup, when needed to move back.
At present, the system cleaning software can not solve this problem, can only be solved by hand.
3, Mtklog folder is your mobile phone built-in logger crawl tool, mainly capture your operation record, MODEM LOG (about the fuselage transmitter record); MOBILE log (recording of calls); NET log (for network-related records) refers to the capture type of the crawler, respectively. If the system is a self-contained tool, you can turn it off and remember to remove the Mtklog folder from your file management (this folder will grow as you use it).
Turn off the logger function steps:
1, click on the bottom right corner of the status bar, find the modem log/other log notice;
2, in the pop-up interface, first click on the modem log, click inside the "Stop" button; Click "Stop" again, return to dot net log, and also click "Stop" to terminate Mtklog work recording.
Also, you need to completely solve this problem, or you need to use the system to remove the logger crawl tool better.
Method One (pro-test effective): Open the Mtklog folder, which has two subfolders config and Mdlog. Delete it, and then create a new two text config and mdlog into this Mtklog folder (I use Jinshan). Then rename the two text and get rid of the. txt OK.
Method Two (to test): Directly delete the Mtklog folder, and then create a new txt format text mtkllog, and then rename and remove. txt is done.
