When I check this in on a Nexus 5 (Snapdragon chipset) I get the issue you have, however, when I check this on my Samsung S7 Edge (Exynos chipset) there isn’t any issue at the same distances laid out. When tested with an Ipad Mini 2 and Iphone 5s (both using A7 apple chipset), I get the same without issue.
Can you post your phones model number from your Device Settings > About Device section. I can test a few more devices here with different chipsets and see if this is possibly something related just to Snapdragon chipsets as a limitation or known issue.
