Unihertz Jelly series
The Unihertz Jelly is a series of compact Android smartphones developed by Unihertz. The line is characterized by its unique tiny-sized smartphones. It debuted in 2017 with the original Unihertz Jelly and Jelly Pro, which were marketed as "the smallest 4G smartphones" available at the time. Since then, Unihertz has released several successors and variants, the Jelly 2, Jelly Star, and Jelly Max. The Jelly Max has been marketed as the "world's smallest 5g phone."
As well as its unusual form compared to typical smartphones, the Jelly series has also attracted attention as a means of reducing problematic smartphone use. Reviews mention that the small display makes it less comfortable to use for games or extended scrolling, while still having full functionality as a smartphone.
The Jelly phones also have an additional programmable button in addition to the standard power and volume switches.
History
The original Unihertz Jelly was initially developed through a successful Kickstarter campaign in 2017, which reached its US$30,000 funding goal within 57 minutes and ultimately raised over US$1.25 million.Following the campaign's success, Unihertz continued developing new Jelly-branded devices, releasing updated models with newer processors, larger displays, and later-generation cellular support.
Unihertz was associated with a previous very small 3G smartphone, the Posh Micro X, which launched in 2015.

Jelly and Jelly Pro (2017)
The original Unihertz Jelly and the enhanced Jelly Pro were released in 2017. Both devices featured a 2.45-inch display, ran Android 7.0, and supported 4G LTE networks in a device weighing approximately 60 grams. The Jelly Pro offered increased RAM and storage compared to the base model.Reviews of Jelly and Jelly Pro were mixed,
but it drew international attention.
There have been accusations of poor battery performance, and network traffic possibly sending personal data to China. Responses claim the network traffic is to speed up apps, and the company has been updating the phone software to improve performance. However, others have disputed this claim. It has received mixed reviews, with some critics calling it "innovative", praising it for its capabilities at such a small size.
