1. The back is made of indecently cheap plastic, even the Chinese are already embarrassed to do this: you can scratch it with the power of thought, if you try, I'm sure. Your fingers for this material is a death sentence. I had to buy a hard Samsung Gradation Cover, a branded accessory cost me 1690 in Sevastopol (this is for a piece of plastic! Samsung, have mercy!), It is thin, does not disfigure the design of the device, but, on the contrary, complements it, as it is made of glossy , transparent polycarbonate with a lilac gradient, the plastic becomes completely colorless towards the top, so my A50 now shimmers in blue-violet (see photo; there are two more color options, if anything: with a black and pink tint). It turned out beautifully, I won’t say anything: almost Huawei, haha. The Araree silicone case was not much cheaper, consider these expenses when buying the A50 in advance. And for a simple case-book, Samsung is already asking for the monthly budget of the sovereign Zhabostan, without embarrassment. Our sellers of Chinese noname-covers, however, also do not lag behind and break 700 for some penny garbage. But I'm just being greedy when it comes to extra bells and whistles, okay. AliExpress, thank you!
2. Harmful screen! To control the brightness of the sAMOLED display, Samsung uses PWM with a low frequency (apparently <240Hz?), with this technique the company achieves stable color reproduction and hides the visual flaws of OLED. I did not expect such a setup (because it's 2022, flicker-free devices are everywhere). You won’t notice PWM with the naked eye, but your vision will still suffer, no doubt. Google details: why pulse-width modulation PWM is such a headache. I wrote to Samsung Members, waiting for their response regarding the OLED Saver application (from the play store), which solves the problem: will it damage the screen? After 10 minutes of reading, I really get sick, to the point of nausea. And you won't return! These are the pies.
3. It seems that the battery is large, the power consumption is optimized, but the charge is still enough for a couple of days.
