Hello,\n\nI'm using a Samsung Tab 4 7" (Android 4.4.2) as navigation device mounted on my motorcycle:\n\n[ATTACH]517[/ATTACH]\n\nIt works quite well (for my needs), unfortunately it loose the GPS signal very often and get minutes to lock satellites again. Also, sometimes it takes minutes for a "cold" start, other times it take just seconds. This behavior appears to me as to be somehow erratic and random.\n\nSo I decided to buy an external GPS Antenna, namely the Globsat BU353S4 equipped with the SiRF Star IV chip:\n\n[ATTACH]518[/ATTACH]\n\nJust after receiving the antenna, I discovered that my Tab 4 version (SM-T230) does not support external devices plugged to his USB port. In other words, it does not support the USB-OTG (On-The-Go) cables.\nEven the power led on the antenna stay off after plugging it to the Tab 4... no signs of life. : (\n\nSomebody else is experimenting this kind of problems in plugging an external USB antenna to an android phone/tablet ?\nWhat (cheap) Android device I should look for?\n\nI've read that the Google Nexus 7 (model year 2013) support OTG natively. Any experience with such device? Should I buy it?\n\n\nThanks in advance for any hint/suggestion.
