User experiences - drops onto concrete - ... Neo1973 Robustness

Physical Dimensions

  • 120.7 x 62 x 18.5 mm (4.75 x 2.44 x 0.728 inch)
  • 184 +/- 5 g (6.5 ounces)
  • For the purposes of acquiring/cutting a properly sized screen protector, the display hole of the case is about 45 x 59 mm, while the top cover internal frame can house up to a 53 x 74 mm protector; sizes much larger than the display hole would obviously necessitate removing the front cover for installation.
  • A Useful size comparison between the Neo1973, iPhone, Motorola A1200 and the SEM600i can be seen at sizeasy

Distinguishing hardware revisions

Inside the U-Boot

Every hardware revision has its own u-boot image type. Thus, the U-Boot has the revision hard-coded. The hardware revision is passed on to the kernel via the ATAG mechanism (ATAG_REVISION)

Inside the Kernel

The kernel receives the ATAG_REVISION during bootup, and saves its contents in the "system_rev" global variable.

From Userspace

The kernel exports the system_rev variable in /proc/cpuinfo as "Revision :" line.

??? So does GTA01Bv4 equal the cat /proc/cpuinfo output of

Hardware        : GTA01

  • CE compliance is needed before a product can be sold in the EU. The CE mark indicates that a product complies to the relevant legislation, defined in the harmonised standards. This refers also to the most relevant, for the Neo1973, Directive 89/336/EEC on electromagnetic compatibility (EMC is the art of assuring electromagnetic compatibility between products). The standards are defined by CENELEC (European Committee for Electrotechnical Standardization), but not verified by any authority. It is the responsibilty of the manufacturer to convince himself that a product is in compliance, and is obligated to be able to prove this (with relevant technical documentation) for a specific product to the authorities on request. Whether the current Phase 1 devices are actually tested against the directives are unknown, no documentation has been disclosed, other than the fact that the devices bear the CE mark.
