Totally disappointed with Google maps. Since early February, it started malfunctioning in real navigation. After several times of re-updating, reinstalling, etc; all of no avail. Every time, it keeps announcing, "GPS signal lost." In fact, it's really devastating. I'm an E-hailing driver and this unfortunate situation have forced me out of business. What can I do? Or rather, Google should restore back the "old version" map hence almost everyone is complaining.
