hi fellow lumians...

i notice that some cable is not compatible with the phone...  or charger...  is this normal(am i the only one who faced this?)....  means that when i use my fiend carger, it will charge on and off... sometimes its charging, sometimes not...  some charger wont charge the [phone...

and i notice thgat the charging rate using powerbank is slow...  i suspect its the cable...  so i plan to chnage the powerbank cable... any recommendation?
btw
