Samsung tests new 7-inch tablet, bigger ones could be 4:3

Last week we told you about a few purported new tablets that Samsung was rumored to be working on. Their model numbers leaked, but today we have another yet unheard of slate making its way to India for testing purposes.
The Samsung SM-T239 has a 7-inch 1,280x800 touchscreen, and mobile data connectivity (since it sports a SIM card slot). Judging by the model number at play this could be the 7-inch version of the Galaxy Tab 5. That fact is seemingly backed up by a user agent profile for the device, which tells us it sports a 1.2 GHz Cortex-A53 CPU. This could be part of the 64-bit Qualcomm Snapdragon 410 chipset, seen in many recent lower-end offerings right and left.

If this is the Galaxy Tab 5 7.0, then it may be joined in Samsung's lineup by bigger models which will have 4:3 aspect ratio displays. The 4:3 aspect ratio has been used by every iPad ever released, though for quite a while the Android world seemed more focused on 16:10. That's starting to change after the release of the 4:3 Nexus 9, and Samsung may want to follow Google's lead on this.
So a new rumor claims that the company's next slates will employ the same aspect ratio as the Nexus 9. The previously leaked SM-T35x and SM-P35x could be 8-inch devices in this situation, while the SM-T55x and SM-P55x might be 9.7-inch offerings.
Either way, all of these tablets are apparently going to be powered by the 64-bit Qualcomm Snapdragon 410 SoC. The SM-Tx5x models may get branded as Galaxy Tab 5, while the SM-Px5x might be new entry-level Note-branded tablets. Don't expect them too soon, though - they're only due to see the light of day in Q2 or Q3. On the plus side, this means they'll launch running Android 5.0 Lollipop, so there's that.
As for the SM-T239, this looks set to stay with the 16:10 form factor, for whatever reason.
