Boris my dear, the reason why android doesen't run smooth on a HTC ONE V isn't the fault of android, one reason is the phone specs, 512Mb(My old LG P500 has the same amount) of ram for example, but the biggest problem is the HTC's Sense UI, it's heavy on phones, especially on low spec phones.
My Nexus runs stock android, as smooth as you csn imagine, just because it isn't filled with bloatware.
Logitek, why did you root in the first place, people usually root for a reason, not because it's cool or something, you know you can catch a STD this way
