[Q] Vibration lost on GT S7562 Duos after PMP Ultra Rom installed

[acenaliu]

Hello

I just installed Ultra PMP v8.5 Rom for my SGS7562 Duos. At the begining I did not paid any attention,
but now I see that the vibration is missing and the phone some time its behaving really slow( Slower than the stock rom)
Should I make e new clean reinstallation or its better to use may be PMP Light Rom
Thanks in advance
