Hey everyone,

I'm trying to understand the whole R36S family, because there seem to be a ridiculous number of models now and the naming is extremely confusing.

I know about:

• R36S
• R36H
• R36XX
• R36 Plus
• R36 Max
• R36 Ultra
• R36 Ultra X
• R36 Max 2
• R36H ProMax / R45H
• R36 Pro
• R36S Ultra

Are there any other models/variants that I'm missing?

What I'm particularly interested in is which ones are actually hardware upgrades from the original R36S, rather than just having a different shell or a bigger screen.

I'm especially confused about RK3326 vs RK3566.

From what I've found, the original R36S/R36H/R36XX generation uses RK3326 + 1GB RAM, while some R36 Max/Ultra versions apparently use RK3566 + 2GB, which would actually be a significant performance upgrade rather than just a cosmetic change.

But I've also seen people saying that some newer R36 Ultra/Ultra X models still use RK3326 + 1GB, so I'm not sure which listings are accurate.

So I upgraded from my R36S to a TrimUI Smart Pro, mainly for better performance and screen quality. On the R36S I had a bunch of PortMaster titles running solid: GTA San Andreas, CS 1.6, a few others, no real issues.

Now I've got CrossMix OS installed on the Smart Pro and I'm trying to get the same games running, and honestly most of them just don't work. Some don't launch at all, some crash on boot.

Is this a CrossMix OS limitation, or is PortMaster itself just less mature on this device?

Is there a better OS for PortMaster compatibility on the Smart Pro (ArkOS? muOS? something else)?

Any known workaround for getting ports to actually show up/launch properly?

Would really appreciate any pointers from people who've been through this already instead of me reinventing the wheel port by port. Thanks in advance 🙏

What's currently the best OS for R36S in 2026? Seeing mixed opinions between ArkOS (most tested/stable) and ROCKNIX (newer, more actively developed, nicer UI). Anyone switched recently and noticed a real difference in performance/compatibility?

Is multiboot the only way to get Linux + Android together, or are there other combos/setups people are running? Is ArkOS and LineageOS only way or ?

Upgraded my SD card to a bigger one from the same manufacturer, same brand/type as before. Flashed the R36S-Multiboot image again, and everything works fine — ArkOS all boot normally. The only thing that won't launch is LineageOS (Android) through the multiboot menu. Just stuck at logo then R36S turns off, while it worked fine on my old card.

Thanks.

Problem: I had no idea what my car really cost per month. Spreadsheets broke, existing apps were bloated.

Solution: carFlo – a tiny iOS app that acts as a digital logbook.

Model:

• Free: 1 car, basic fuel and service logging
• Pro: monthly/yearly – unlocks unlimited cars, unlimited entries, business mileage tracking, photo receipts, VIN storage, CSV export, iCloud sync

Target: private drivers with high mileage, families with 2+ cars, taxi/delivery drivers, small fleets. Basically anyone who needs proof of maintenance for resale.

Solo dev, no funding.

Traction: just launched on iOS, zero ads. Android version shipping next week.

What I'm testing: is $3/mo too much for "peace of mind you won't forget an oil change"? Would you pay yearly to get export for your mechanic?

Open to brutal feedback on pricing and positioning.

After losing my service history for the third time, I finally built my own car app.

carFlo is basically a digital service book. It tracks fuel ups and gives you real L/100km or MPG, logs every service and repair, reminds you about registration, insurance and oil changes by date OR mileage, and lets you snap photos of receipts so you actually have proof when you sell.

I built it for myself first because spreadsheets got messy. Core tracking is free forever – one car, basic logs.

I added a Pro version for people like me with 2 cars and a work van: unlimited cars, unlimited fuel and service entries, unlimited reminders, business trip tracking, VIN/chassis storage, photo receipts, full CSV export and iCloud sync. It's a simple monthly or yearly sub.

It's iOS only right now, Android is almost done.

Took me about a year solo. Curious what you think – would you actually use something like this?

U potrazi sam za polovnim autom, budžet mi je 6.000 – 8.000 €, i jedan od glavnih kriterijuma mi je što bogatija serijska oprema.

Marka mi nije toliko bitna– bitno mi je da auto ima npr:

- Multifunkcionalni volan
- Multimedija (ekran na dodir)
- Apple CarPlay / Android Auto
- Kamera
- Parking senzori (prednji + zadnji)
- LED svetla
itd itd.

Godište me ne ograničava previše ako je auto dobro opremljen, ali realnije gledam 2015+.

Koji modeli su poznati po tome da dolaze bogato opremljeni već u osnovnim paketima? Gledam sve marke, ne vezujem se ni za šta konkretno.

Hvala unapred! 🙏
