Both problems are caused by an incorrect implementation of the frame buffer's page flipping. Key events are captured, but the graphical interface appears to drop every other frame.
-Android relies on a double buffer to smoothly render page flips (please see Functionality for details).

For more information on the general Android security principles and signing requirements, see the Android Security and Permissions section in the Android Developer Guide). The core Android platform uses four keys to maintain security of core platform components:
+home/contacts process.media/download system.These keys are used to sign applications separately for release images and are not used by the Android build system. The build system signs packages with the testkeys provided in build/target/product/security/. Because the testkeys are part of the standard Android open source distribution, they should never be used for production devices. Instead, device manufacturers should generate their own private keys for shipping release builds.
A device manufacturer's keys for each product should be stored under vendor/<vendor_name>/security/<product_name>, where <vendor_name> and <product_name> represent the manufacturer and product names. To simplify key creation, copy the script below to this directory in a file called mkkey.sh. To customize your keys, change the line that starts with AUTH to reflect the correct information for your company:
+#!/bin/sh +AUTH='/C=US/ST=California/L=Mountain View/O=Android/OU=Android/CN=Android/emailAddress=android@android.com' +if [ "$1" == "" ]; then + echo "Create a test certificate key." + echo "Usage: $0 NAME" + echo "Will generate NAME.pk8 and NAME.x509.pem" + echo " $AUTH" + exit +fi + +openssl genrsa -3 -out $1.pem 2048 + +openssl req -new -x509 -key $1.pem -out $1.x509.pem -days 10000 \ + -subj "$AUTH" + +echo "Please enter the password for this key:" +openssl pkcs8 -in $1.pem -topk8 -outform DER -out $1.pk8 -passout stdin ++
mkkey.sh is a helper script to generate the platform's keys. NOTE: the password you type will be visible in your terminal window. Note the passwords you use as you will need them to sign release builds.
To generate the required 4 platform keys, run mkkey.sh four times specifying the key name and password for each:
+sh mkkey.sh platform # enter password +sh mkkey.sh media # enter password +sh mkkey.sh shared # enter password +sh mkkey.sh release # enter password ++
You should now have new keys for your product.
+ +Signing a build for a release is a two-step process.
+Use build/tools/releasetools/sign_target_files_apks to sign a target_files package. The target_files package isn't built by default, you need to make sure to specify the "dist" target when you call make. For example:
+make -j4 PRODUCT-<product_name>-user dist ++
The command above creates a a file under out/dist called <product_name>-target_files.zip. This is the file you need to pass to the sign_target_files_apks script.
You would typically run the script like this:
++./build/tools/releasetools/sign_target_files_apks -d vendor/<vendor_name>/security/<product_name> <product_name>-target_files.zip signed-target-files.zip ++
If you have prebuilt and pre-signed apk's in your build that you don't want re-signed, you must explicitly ignore them by adding -e Foo.apk= to the command line for each apk you wish to ignore.
sign_target_files_apks also has many other options that could be useful for signing release builds. Run it with -h as the only option to see the full help.
Once you have signed-target-files.zip, create the images so you can put it onto a device with the command below:
+build/tools/releasetools/img_from_target_files signed-target-files.zip signed-img.zip ++
signed-img.zip contains all the .img files. You can use fastboot update signed-img.zip to use fastboot to get them on the device.

System Properties
+The following RIL-related system properties are set by the RIL library:
+ro.ril.ecclist: list of valid Emergency Call Codes, for example, 911. Values are read from EF_ECC on the SIM and possibly supplmented by tables based on operator, network, or manufacturing code.The following RIL_related system properties are available to the RIL library:
+ro.ril.hsxpa: inidcates hsxpa support of target network.ro.ril.gprsclass: inidcates GPRS class of target network.ro.ril.enable.3g.prefix=1: adds the 3G prefix to the operator name.
