Summary and Solutions of v880 for oranges

1. Failure of distance sensor
I tried to download the original version. I also brushed a lot of rom a few days ago. Sometimes it does not work. In my experience, don't start the machine and try again immediately. At this time, it will often fail. It may take a minute or two to install more software. If the Rom is 2.1, press * 983*0 # on the dial to enter the test interface. There is a g-sensor test at the bottom. Change testing light to testing proximity, and move the two fingers together in the phone receiver. Let's see if the Line X: No under proximity changes to X: yes when the finger moves closer to the listener. If the state changes, the sensing is effective.

2. How to differentiate whether it is an O screen or a t screen?
If you have seen the O screen, you can see it at a Glance. It is very difficult for us to have these children's shoes.

The O screen and T screen are not the differences between the visual angle and definition.
Method 1: Enter the project mode to view: Enter * 983*0 # In the dial-up panel to test the item under battery. If the display is LCD, It is a t screen, the displayed OLED is an O screen.
Method 2:
You can find the internal version number-set | about the phone number | version number

The TFT screen device has a version number.
Ouk_p729bv1.0.0b08
(This buid can also be available for OLED-but few)
The version number of the device on the OLED screen already exists.
Ouk_p729bv1.0.0b05

3. How to extend the battery usage of Android phones
(1) Reduce the screen brightness. You can choose Settings> sound and Display Settings> brightness to adjust the screen brightness to a proper value. In fact, even if the screen brightness of the Android phone is adjusted to a minimum, the screen brightness can be clear, but it can effectively save power, for mobile phones that support optical sensors, you can also select "automatic brightness" to automatically adjust the screen brightness based on external light. You can also download widgets that adjust the screen brightness at any time in the marketplace.
(2) Disable WiFi, Bluetooth, GPS, 3G, and 4G when you don't need it. Many mobile phones have built-in widgets that enable or disable the above functions, if not pre-installed, you can download the toggle widget software from the Android Market.
(3) Disable Wi-Fi and 4G network reminders. Choose "Settings"> "wireless and network settings"> "Wi-Fi Settings" from the mobile phone menu to deselect the Network Notification function.
(4) disable the data roaming function. Choose "mobile phone menu settings"> "wireless and network settings"> "Mobile Network Settings" to deselect "data roaming". Canceling data roaming can save a lot of cell phone power, and does not affect Program And mobile phone network functions, the program can still connect to the network at any time. // Canceled by default
(5) Disable account synchronization. If you do not use Google services such as Gmail, you can disable automatic synchronization by setting-> account and synchronization. Automatic synchronization automatically synchronizes your calendar, contacts, Gmail emails, and photos to the Google server in the background of your mobile phone. disabling the automatic synchronization function can also save network traffic.
(6) Reduce the screen standby timeout time. Set-> sound and display settings to select the appropriate screen standby timeout time. You can select 15 seconds, 30 seconds, 1 minute, 2 minutes, 10 minutes, 30 minutes, or never time out. If you select a short screen time-out period, the black screen of your phone is often displayed. We recommend that you set it to 1 minute.
(7) manually close the screen when you don't need it. This is a very good habit of saving the battery, but it takes some time to develop. Every time you read the phone and put it into your pocket, press the power button (hanging key) the black screen of the mobile phone can be used. This is a good habit of low carbon and increasing the power of the mobile phone.
(8) Disable background data synchronization. Choose Settings> account and synchronization to cancel background data selection. Note that this may cause some network programs to not work normally. // Enabled by default.
(9) Reduce the synchronization frequency of Automatic Updates. Android has many programs that support automatic data synchronization, such as weather programs, news programs, stock scores, and social network programs such as Twitter, you can change the synchronization frequency of these programs to save power.
(10) disable the wireless network positioning function. If you do not use Google maps or other programs that use your geographic location, you can disable the wireless network function by setting-> location and security settings. // Disabled by default
(11) Close the window animation effect. Although these animation effects look cool, they actually consume a lot of power. If you don't care about the display effect on your phone, you can choose Settings> sound and Display Settings> animation> No animation to close the window animation effect. // Disabled by default
(12) do not use live wallpaper. Live wallpaper is a new feature only available in the android 2.1 system. It also looks cool, but also consumes power and mobile phone resources, changing a static wallpaper not only helps your mobile phone node, but also makes your mobile phone run more smoothly.
(13) using a low-brightness wallpaper is a pure low-carbon demonstration. Although it may not be able to help you cut off the power, if there is a suitable wallpaper, change it.
(14) disabling the Wi-Fi sleep policy may sound incredible, but after the Wi-Fi sleep, the mobile phone automatically switches to the 3G network, 3G networks may consume more battery power than Wi-Fi. You can choose Settings> wireless and Network Settings> Wi-Fi settings, then use the menu key, select advanced options, enable the Wi-Fi sleep policy, and choose never sleep to disable the WiFi sleep policy.
(15) monitor your mobile phone process (consider using the task killer management process). After Android 2.1 starts to support the service management function, choose Settings> application settings> running services to disable unnecessary services to save power. In addition, we recommend you download the task killer process management software to kill unwanted processes at any time, the node can also save the cell phone memory.
(16) Be careful when selecting your screen Widgets. widgets (window widgets) are the most easy to use, because many widgets need to access the network in real time, such as Twitter, news, stocks, email, weather, and other Widgets may quickly consume your power, so please choose carefully.
(17) Turn off the color of the LED reminder light. This is a useful function for some people. You can use the color indicator to determine whether there are unread emails or missed calls, but for most people, it can be disabled.
(18) disable the mobile phone vibration. In addition to preventing phone leakage and other such events in a noisy environment, do you have any reason to shake your mobile phone, at least in the office and home, you can set-> sound and display settings to disable the mobile phone vibration.
(19) Turn off the button operation sound, which is one of the features that I think are least used. You can turn off the phone operation sound by setting-> sound and display settings.
(20) closing the touch feedback is also the first function you should disable. You can choose Settings> sound and display settings to cancel the selection of the touch feedback.
