The advantage of the operating system Android is the ability to optimize and customize it for your needs. For example, editing the system file build.prop will allow you to add a couple of improvements to the system.
At the moment, you can find many programs in Google Play that will allow you not only to change the appearance, but also to rewrite some system files. But it is manual editing that will allow you to clarify everything that is happening.
Where to find the build.prop file
First we need to teach Root rights. Now we need to get to the build.prop file itself. To do this, install any file manager (for example, ES Explorer) that has access to system files. Open it and find the system folder. It is in it that the build.prop file we need is located.
I recommend saving the original file separately.
You can edit it either on the device itself or on your computer.
Change build.prop
To edit a file on a computer, we need to copy it to the built-in memory of the tablet/smartphone and transfer it to the computer. To open and edit Andoid system files, I usually use Notepad++, but if you don’t want to install additional programs, you can use the standard application — Notepad.
- Click on the build.prop file and select "Select a program from a list of installed programs"
- Now select the notebook.
- Now our build.prop file will always open with notepad.
The first lines describe in detail:
- ROM name and version
- Android version
- Model, brand and manufacturer name
Editing this data will allow you to change the model name or, for example, the Android version. Just make changes in the corresponding lines.
Warning: Entering this data may cause errors in the operation of the device.
But all this is just a joke. It's time to move on to tweaks that will improve the operation of your tablet or smartphone.
Open the build.prop file and add the records you need. The principle of adding a record is simple:
- Enable text search (ctrl+F)
- Find the required line
- Replace the data in it
- If the line is missing, add it yourself.
List of tweaks (settings) for build.prop
Disable animation on boot
After entering this data, your tablet will boot almost instantly.
- debug.sf.nobootanimation=1
- ro.config.hw_quickpoweron=true
- persist.sys.shutdown.mode=hibernate dev.bootcomplete=0[/su_box]
Improving energy saving
- ro.ril.power_collapse=0 pm.sleep_mode=1
- wifi.supplicant_scan_interval=120 (sets the Wi-Fi scanning interval)
- ro.mot.eri.losalert.delay=1000
Optimization of 3G operation
In theory, it increases network speed
- net.tcp.buffersize.default=4096,87380,256960,4096,16384,256960
- net.tcp.buffersize.wifi=4096,87380,256960,4096,16384,256960
- net.tcp.buffersize.umts=4096,87380,256960,4096,16384,256960
- net.tcp.buffersize.gprs=4096,87380,256960,4096,16384,256960
- net.tcp.buffersize.edge=4096,87380,256960,4096,16384,256960
- ro.ril.hsxpa=2
- ro.ril.gprsclass=10
- ro.ril.hsdpa.category=10
- ro.ril.hsupa.category=5
- ro.ril.enable.a53=1
- ro.ril.enable.3g.prefix=1
- ro.ril.hep=1 ro.ril.enable.dtm=1
- ro.rill.enable.a53=1[/su_box]
Disabling error messages
- profiler.force_disable_err_rpt=1
- profiler.force_disable_ulog=1[/su_box]
Changing screen density
Basically makes icons larger or smaller.
- ro.sf.lcd_density=160
Improving system responsiveness
- debug.composition.type=gpu
- debug.composition.type=dyn
Add the lines you need to the build.prop file, save the changes and drop them into the folder system, overwriting the original.
After you restart your tablet, the changes will take effect.
