Philips SmartTVs offer hundreds of apps when all of the available content is considered. Depending on which TV you own, see below guides to finding additional applications. Note that 2017 and earlier televisions with Samba and Xumo have model numbers ending in 02, 01, or 00 (ex. 55PFL5602/F7). 2018 televisions powered by VEWD will have model numbers ending in 03 (ex 55PFL5603/F7).
Why do I not see as many apps on my Philips TV as were advertised?
