For the grandmother, the minimal mode built into the Red Mobile phone series is ideal for the elderly. My grandfather's "Samsung NOTE 3" brush is the minimalist desktop that MIUI installed. Grandpa can study together when grandma is not used.

Minimalist mode
If it is to buy for the elderly, it is recommended to buy red rice series.
This minimalist mode allows at least the elderly to answer and send a text message, and then to play a micro-letter, work together.
My grandmother only occasionally answered calls and pictures and used it lightly for five days.
My personal point of view is that it is not recommended to buy functional machines for the elderly. First, it is not convenient for old people to use functional machines. Second, China Unicom Telecom is retreating 2G networks. Most of the functional machines are only 2G. Poor, but it causes trouble for the elderly.

Bi Directions Thyristor (Triac)
Bi Directions Thyristor (Triac) is equivalent to the antiparallel connection of two unidirectional thyristors, but only one control pole.
Bidirectional thyristors are made of N-P-N-P-N five-layer semiconductor materials, and three electrodes are also derived from the outside. Its structure is shown in the figure. Bi-directional thyristor volt-ampere characteristic curve Since the forward and reverse characteristics of the bidirectional thyristor are symmetrical, it can be turned on in any direction and is an ideal AC switching device.
