As far as “touch-sensitive frame”, it could be the result of following:
“ZTE claims to devote 10% of its annual revenue on research and development each year, and it could be producing patents and utility licenses at a furious pace.[18][19] ZTE has filed 48,000 patents globally, and with more than 13,000 patents granted. 90% more patents are invention-related. In two consecutive years (2011 and 2012), ZTE has been granted the largest number of patent applications globally,[20] which is the first for a Chinese company.[21]”

BTW: As far as Phone goes:
“By 2008 ZTE could claim its customer base was truly global, as it had made sales in 140 countries.[13]
In 2009, the company had become the worldwide third-largest vendor of GSM telecom equipment, and about 20% of all GSM gear sold throughout the world that year was ZTE branded.”
Started out doing photography at the age of 6 using an uncle's old 1940 kodak brownie box camera. At 15 years of age, I decided to buy my very own 1975 Praktica SLR camera. I now shoot with a Nikon D850. I do unpaid TFP and commercial paid work.
