[GIS] Surveys showing GPS accuracy in different models of smartphones

Question

Are there any surveys that give accuracy in meters for different smartphones (e.g, iPhone 6: 8 meters, Samsung Galaxy S8: 7 meters) regardless of what the statistical method is being used?

Answer 1

Tomaštík Jr. et al. (2017) investigated the Horizontal accuracy and applicability of smartphone GNSS positioning in forests.

In Table 1, one can visualize which smartphones were used in the research:

• ZTE Blade (Android 2.3).
• LG G2 (Android 4.4 and 5.0).
• Sony M4 Aqua (Android 5.0).
• Other non smartphone devices.

It is not a extended list of smartphones (only 3), but I found it interesting because it gives an idea of what precision one might get under forest areas (leaf-on and leaf-off) in comparison to open areas; and what types of GIS tasks/operations one would expect to take advantage using smartphones (in context of forestry):

... The results indicate that ‘smart’ devices can be a low-cost alternative for forestry tasks with lower accuracy demands, e.g. under-canopy navigation, preliminary detection of points of interest, mapping of linear and polygonal objects of interest. Further benefits of smartphones, like the possibility of logging the data to central databases in real time, can make them competitive with other GNSS devices.
