I have been enjoying numerous movies on VLC Player and videos on YouTube since receiving my PPMax towards end-Jan 2020. Really loving it and with each firmware update, it gets better.
However, there is one issue which particularly annoys me and that is the problem of audio lag and stutter from some Bluetooth speakers. The interim solution for me has been to remove a battery from the AirMote when not using it during a movie. Put back battery when need to pause and remove again when movie resumes. While this interim solution worked great for me, it is still annoying.
Another annoyance is having to point and type on the on-screen keyboard when searching YouTube.
In my search for a better solution, I bought this Rii i4 Mini Bluetooth Keyboard with Touchpad that also has a scroll wheel.
It pairs easily with the PPMax and fits comfortably on my hand. So far having watched 3 movies (with AirMote battery out), no audio lag or stutter and it has worked great for movies on VLC Player. But on YouTube, sometimes the audio still has the occasional stutter which I don’t know why. I can control the volume, pause/play, rewind/forward, home, etc. The touchpad is responsive allowing me to navigate the screen with ease. When scrolling through a long list of movie files, although I can use two-finger drag to scroll, I find that the scroll wheel really came in handy for this task. Or, now that I have a physical keyboard, I could use the search function and easily type and find the movie I want.
Only a couple of things I cannot do with it is power on/off and trigger auto-focus as there are no such dedicated buttons on the Rii i4 keyboard. For power, I use the physical button on the PPMax. If I need to trigger auto-focus, I need to put back the battery in the AirMote.
The Rii i4 is powered by a rechargeable battery and has a physical on/off switch. Has a backlit keyboard. Also comes with 2.4GHz dongle if you do not wish to use Bluetooth.
If anyone if looking for a keyboard with touchpad, this is Rii i4 is a good alternative and worth checking out.
