Mobile devices for webpagetest

hi i am using webpagetest private instance from 2 years , at that time i installed nexus phone , note 2 phone at various location , now some of devices are not working due to 24*7 test running , what are good option to buy phones which will work at least 1 year . can i use android os > 5 devices

MotoG’s are a cost effective, and pretty reliable option for Android test agents

Thanks andy davies

is it ok if i use latest motog with Android 6.0 Marshmallow OS , never tried mobile agent with 6.0 OS

You should be able to. That said, KitKat has been by far the most reliable and consistent OS for my test devices and I still like using the Gen 1 MotoG devices (doesn’t hurt that they are only $79 new):
