Hey there. I bought a little used nokia n900 for couple of days ago and it was alot of stuff on it when i had it but everything worked fine and the browser was doing a great job. I restored my phone to original mode and after that i put 10 gb of music, i installed debian and openoffice aps and i packed my desktop with some shortcuts and of course downloaded some apps and now it is a bit slower. For example in the begining i could watch live stream football match on my browser and it worked fine but now it lagges and are really slow.
How can i fix this?
