1. The rom is a bit laggy. Lags appear every now and then which becomes a bit irritating.
2. The air command window can be opened but it freezes there itself if attempted to close and the device then needs to be restarted to solve the issue.
3. Multiple sound engines always cause some issues. So i suggest to keep only Viper in the rom. Viper works flawlessly.
4. The S note and sketchbook apps are very much slow.
More detailed review coming soon
P.S Thanks again
