Lets say,i want to buy the new phone and i want to delete MyCellium(linked to ledger nano s)from old phone,and after this install MyCellium to new phone(and link it back to ledger).

Do i still have btc in my Ledger(after deleteting MyCellium) and MyCellium wallet, or i only will have btc on my ledger and to use it with MyCellium i have link it with ledger from the scratch?
