My primary device is my laptop, I have my email addresses set up in thunder bird, over the past few months I have had an increasing number of queries of whether I received a mail or not, I find those mails on my android phone with all the others that I can see on the laptop, the problems are the screen is too small to read the mails, I cant print from the phone, I only normally use the phone for a small amount of texting when required In Thunderbird it does not matter how many times I press get new messages , these messages are not downloaded .
