Samsung Galaxy A30: Phone vibrates and shows sign of life but shows blank screen

Tue, 13 Jan 2026 02:49:31 -0700

My phone's screen has been blank and doesn't show anything. I've tried doing a soft reset (volume down + power button) and got it to vibrate showing that it's restarting but it still doesn't show the Samsung logo or the home screen. I've even connected it to my computer and was able to see it as a MTP device, and when I did a soft reset of it while it was connected, my computer played the USB disconnect sound and then the USB connect sound showing it is still alive. Is there anything else that can be done to get rid of this "black screen of death" or whatever it is ?

Samsung Galaxy S6: Can't disable ultra power saving mode.

Sun, 02 Jul 2023 22:05:17 -0700

After using ultra power saving mode for a while, I charged my phone and tried to disable it but there is a glitch and disable upsm option doesn't appear in the settings.

It seems as if the problem came about when I swapped to Google now launcher from touchwiz and set it as the default app when I touched the home button in upsm.

I've tried wiping the cache partition, rebooting in recovery mode and when I go into doing mode it just says that it's downloading a custom os and nothing happens on the screen for hours

Also can't back up the phone to kies because I can't use it as a USB connection in upsm. I really really need a few voice recordings from the data but the contacts etc is synced to my Google account.

Any advice?

My phone is cracked really bad in the front and back. Now it has a permanent greancolor line across the screen.It also had one black spot and i can't see anything behind that spot. When i use my phone a green screen flickers and then covers my entire screen. while this is happening my screen still works, i can feel the vibrations when i touch the screen.
