Even newer devices can lack an HEVC hardware decoder, especially budget devices.

Most devices produced before 2014 do not have an HEVC decoding chip. However, things are different regarding the relatively new HEVC standard.
HEVC CODEC PACK ANDROID
Nearly all Android devices manufactured after 2011 feature some sort of a hardware AVC decoder, which allows them to play most videos encoded using AVC fluidly. Decoding both AVC and HEVC videos is very demanding in terms of processing power and software decoding can be very slow on some CPUs. Decoding can be done by the CPU of the device (known as software decoding) or by using a special chip, designed to carry out this task quickly and efficiently (known as hardware decoding). In order to be able to play these videos, they must first be decoded. While AVC playback is supported out-of-the-box, even on older Android devices, playing HEVC videos on Android can be tricky. Some have even got one step further and already disabled AVC videos support. Major websites have already added support for HEVC videos.

HEVC videos are slowly replacing AVC videos on the Internet. It was developed following the same concepts as H.264 and manages to provide substantially higher video quality than H.264 at the same bit rate. High-Efficiency Video Coding (HEVC), also known as H.265, is a video compression standard, regarded by many as the successor to the AVC (H.264) standard.
