Same issue, August 2019. App and cameras worked great for 1 week (bought on prime day). Then 1 camera showed green bar and bad colour bleed. Then another camera showed green bar and the other camera is patchy discolored.
Running latest Android app version of blink. ANDROID 9 which hasn’t been updated since I got the blink cameras.
Uninstalled app, reinstalled. Wiped cameras and sync box and, batteries out etc.
Same issue remains. Is there a technical issue for this, seems a lot of people with this same issue.
