Screen size

Approximate rectangular screens calculated from recorded diagonal and aspect ratio at one relative scale. Rounded corners and cutouts are not subtracted. These are not phone outlines or calibrated actual sizes.

1. 1. JAMA

   Screen diagonal:

   2.4 in

   Aspect ratio (height:width):

   4:3

   Approximate rectangular screen area:

   17.8 cm²

2. 2. SP4m

   Screen diagonal:

   2.2 in

   Aspect ratio (height:width):

   4:3

   Approximate rectangular screen area:

   15 cm²

JAMA has approximately 19% more rectangular screen area than SP4m.

Memory variants

Each row compares the same storage capacity. Cells show recorded RAM alternatives, not combined maxima. Not recorded does not mean unavailable in every market.

No unambiguous storage/RAM pairings are recorded. See the original specifications below.

Practical features

Explicit Yes and No values are shown directly. Qualified or regional records retain their details. Unknown means the record is missing.

Battery capacity

Capacity is not battery life. No endurance test is implied.

Open a section for more detail. On narrow screens, swipe sideways or use Left/Right arrow keys while the table is focused. Unknown means missing data, not No. Recorded zero values are shown as recorded.
