What I checked
The official description names seven appearance controls. allthings.how supplies a sample early phone and the screen-cost observation; Roonby describes resolution, refresh rate, camera, and cost tradeoffs. These are sourced starting points, not tested best builds. None of those sources establishes a 4.8 review cutoff or an optimal design for every year.
For the correct game and starting resources, see the game overview and reported codes.
Levers on the design screen
Official description. Effects are from the 10 October guides where noted.
| Lever | What to weigh |
|---|---|
| Screen size | Higher unit cost. allthings.how: not an automatic review penalty |
| Cameras | Front plus rear on the sample first phone. Extra cameras are not priced in public |
| Corners and buttons | Shape options. No sales number attached |
| Colour, finish, logo | Roonby: appearance does not guarantee sales |
| Parts | Storage, RAM, CPU, battery, network, OS. Early sample is on the beginner guide |
| Price | Set against unit cost. Use the calculator. Do not copy a stranger’s layout price |
A sourced early build and an upgrade method
The sample 2007 phone in allthings.how is a 6.1 inch 320p device with Micro USB, 4 GB storage, 128 MB RAM, a 400 MHz core, a 1000 mAh battery, and 2G. That is a starting point, not a forever build. RoboOS has to be researched first.
Roblox lists tablets, smartwatches, earbuds, foldables, laptops, AR headsets, and drones as research unlocks. It does not specify the year or required sequence for each. The research guide explains choosing the next useful technology rather than inventing a 2015 flagship.
Ship one configuration, read reviews and sales, then change a single lever. Shipping the same parts again is the stall described on selling phones.

FAQ
What phone scores 4.8 or higher?
No sourced guide gives that threshold. I am not publishing a fake cutoff.
Does a bigger screen always win?
It costs more. allthings.how says it does not directly cut the review. Whether buyers pay for it is a sales reading, not a rule.
Can I copy a YouTube layout?
You can copy the parts if they exist in your year. Refresh rate and panel type show up in Roonby’s option list, but not as a ranked best.
