will check if i can get hold of 502 phone for a day or two.
anyway can you tell how much Free RAM you have in 501 when using it normally.
I am using ZDBOX and it helps me free up more RAM for smoother operation
I usually have 100-150MB free RAM with zdbox, whatsapp, maps,gmail and few others remain active 24x7
With out whatsapp and gmail.. I have around 180 mb free ram.. And when i restart my phone it shows 260 mb free.. Bt after using it for few hours. It drop down to 180-220 mb..
