You are really lucky that you can go to bootloader without power key.well it's worth spending $10 for the screen, but my phone has other issues as well. that's why i'm not sure...
power button is not working, charging speeds are slow and the battery is quite old.
i modified the system so this phone just turns on when you plug a charger, no off-mode charging. that mostly solves the power button problem. don't know if the slow charging is due to old battery or the replaced charging board but these problems are making this phone hard to use. its just a decent backup device for now. it was a good device in 2015 standards, 3gb ram and 8core cpu on a mid-range device? sure. but now its quite old ^^
i'm just glad that i can access to the fastboot and recovery without power button lol. otherwise it would be a brick without power button repair.
I also had the problem of slow charging and rapid battery discharge, which was solved by replacing the battery.
Definitely worth spending $10.
Yes, it was very smart in its time and compared to the phones of that time. Of course, it is still enough for me as a first phone with daily use. And I am satisfied. Thanks to you for having an up-to-date and flawless operating system. However, in the screen protector, I select the analog clock when charging, and after disconnecting and connecting the charger once, it returns to the digital clock, and this is strange. Of course, it is not a problem. I just wanted you to know.
