I tried Calls Blacklist and it works well for me.
My Android phone got very slow. It started about a week ago. When I visit Gmail, for instance, I have to wait minutes until my new messages appear. If they appear at all… Often, messages are not updated. I click on “refresh”, I wait 2 minutes, but I still get the old messages. What da hell?
In this forum thread I found the following tip:
“EDIT: I found the solution… Go into the Market and install AdFree. Update the host file and reboot to clear DNS, everything back to normal. Myn’s is preloaded with the Adfree host file and it became outdated.”
AdFree requires root privileges. Doing the rooting process and installing AdFree, my phone got much faster :) I need a few more days/weeks to test it but it looks promising.
In short: install the application ConnectBot from Google Play and type “
su” in the console. If it switches to root (in this case the prompt changes to ‘
#‘), then your phone is rooted.
Here are some links that describe how to root your Huawei Ascend Y200 Android phone. If something goes wrong, I take no responsibilty! This is for educational purposes only.
