Hi all i have used miui before on other phones and love it but on my sgs2 every so often i get a random freeze up while using the market and results in my phone re starting. Any ideas? Also why is it the keyboard never vibrates on key press even though i have set it to. This has always been the same on all my phones with miui. Noticed that it workes in the galnet version though. Any ways to fix these problems would be great.
