Have to agree with another person's letter, I read in the forums. Airdroid is a great idea when it is working but a real pain in the bum to get it to function correctly. Even if you get it going one day, that is no guarantee it will work next time you need it.
Have tried all the suggestions above and/or combinations there of, with mixed results but none is permanent.
Despite many e-mails to your support team, I have only received one reply. That gave me the latest version of Airdroid, which is what I had and did not make any difference!! If this is your idea of a support team and customer service then quite frankly it sucks.
My overall impression of Airdroid is as stated above, a great idea but full of bugs that needs to be sorted because as the forums testify it's got too many problems to be viable.
All this hassle just to replace an USB cord. Thanks but no thanks. It's just one hassle too far. My phone is a Motorola Defy. Once I attach the USB Cord, I can go to My Computer Folder and find my phone and card. No problem - simple!! Get the tech knowledgeably and Customer service sorted or come to an end. Don't be half arsed about it.
Wish you the very best for the future but I want no further part. Please delete my account from your files.
