The higher weight prompted us to send back, although the smartphone else leaves a good impression and runs smoothly (as far as I can tell that after a short trial and error). Only after leaving Apps the device sometimes (all the internal memory) did not begrudge a few commemorative seconds before icons were again fully displayed. The G510 is a good choice if weight is not a greater role. But due to heavy weight and its misrepresentation I give only 3 Stars.
