Apollo15

I recently bought a 2013 GS with nav. My Droid Bionic would not support the Enform apps such as Bing, Yelp, Pandora, etc. I purchased an Apple 5 from Verizon & it is very compatible with the system. If the screen size is large enough for you, this is probably the most reliable choice for compatibility based on my conversations with Lexus tech support & my local dealer's tech guy (who has been very helpful.) Unfortunately, my Baby Boomer eyes could use a larger screen. I would like a Samsung Galaxy S4. I have checked the compatibility on Lexus' web site & although the S3 is very compatible, the S4 (which uses a newer Android OS version) has not been tested. Neither Samsung tech support nor the Verizon reps have been able to give me any definitive answers. Unfortunately I can only try one other phone by trading in the Iphone 5, and I am then stuck with that model. I have 7 days left on the return period. I was hoping someone has used a Galaxy S4 (preferably Verizon) with the large screen 2013 nav system & can give me pros or cons they have experienced with the Enform apps & phone use. Help! Thanks in advance, Steve
