This was happened to me, I was so careless and stupid for not saving my private key or even my recovery phrase in another storage like USB flash drive or write on a  notebook instead. I lost my phone and all the important files and now how can access my online wallet? I even lost three physical wallets that is how negligent I am.  This thread is a must read for all members specially us newbies, this will serve as a reminder and a guide on how to protect our online assets. I must be attentive and careful next time, I have learned my lesson.
