Using a bluetooth keyboard for my smartphone

I seriously want to challenge my new Samsung Note 9 to be my writing machine on the run.  I had lost my Note 10 sometime back.  That one had a special keyboard I could use specially for writing.  But the Note 10 after a big drop decided to die.  Well not straight away.  The display went berserk and I couldn't even guess what was being displayed nor could I respond in any way. 

I had the option of perhaps buying a refurbished Note 10 which would cost me around $300.  For the same price I could also buy a small netPC which will be used for the main purpose of writing on the run.  So two options were there.  But there was another one since I bought the Note 9.  And that was to buy a bluetooth keyboard to connect to the Note 9.  So I bought one for $59 from JB Hifi.  The ticket price was $69 but I was charged $59 only.  Maybe there was a discount for the item that day.  I didn't even dare ask as the cheaper price was to my advantage.

I tried to connect to the keyboard.  I had problems initially with connecting but eventually after scanning devices from the Bluetooth settings, I was given the chance to connect by entering a series of numbers on the keyboard and voila I was connected.

I proceeded to test my comms apps.  Facebook worked.  I was able to post a longish entry in a FB page.   I was able to respond to comments etc.  Viber worked.  No problem there - quite straightforward.  Just click on the text box and type on the keyboard.  Messenger however failed dismally.  It seemed to accept one letter in the text box and then it closes the text box.  I could then not really type in the text box without repeating the process of opening the text box, entering one letter, then opening the text box again and entering the next letter and so on.  So no good.  I still have to figure out how to make this work.

My next step will be to find the best app I can use for writing.  Research is still under way.
