Anthony can probably help, but if you have your password saved on your phone so that you can access the Forum via it anyway, I think it'd be a fair bit quicker & easier if you changed your password on your phone.... AFAIK, it doesn't matter what type of smartphone it is; I've changed my passwords regularly on a variety of Samsung phones, altho mine have mainly been Samsung Notes... :dontknow:
Still, if your password is not saved on your phone so that it'll default into the password field, you will need Anthony to help, so you'll hafta send him a PM or a msg via the Contact Us link down the bottom of every page; once he gets that PM/msg & satisfies any ID concerns (which might take a while, possibly 24 or more hours by the time all the back & forth is done?) & then gets the time to actually do it; he'll be able to over-ride your password with a default password; which he then has to send to you; and then when you get that msg and log on using the default password, you'll hafta go into your profile and change that default password into something else that's meaningful/useful to you.....
If it is saved on your phone, you can go to 'my profile', find 'Forum Actions' in the menu bar up the top of that page, select 'edit profile', the select 'Edit your email & password' - if you've saved your password for the Forum in your phone, it should default that password into the 'enter old password' field; then you fill in the 'new password' & the 'confirm password' fields; and then hit 'submit'. And this same process is effectively what you'll need to do if you hafta go to Anthony for a default anyway, except that in that case you'll need to manually enter that default password into the 'old password' field.
Hope that lot's of some help, sorry I can't do more for you myself, but that's how it is. Good Luck! :thumbup:
