LG K7: Phone no longer connects to cellular service after restart.

Tue, 28 Feb 2023 11:21:31 -0700

A few days ago, I restarted my phone after clearing some data on my device in an attempt to save storage (my phone was warning that my storage was low, so I deleted the phone's cache and the "Android" selection in the storage's "Miscellaneous" grouping after making sure all apps and/or media that could be stored on the SD card was.). As it finished rebooting, I noticed it failed to play the T-Mobile jingle as it normally would while rebooting. Upon completing the reboot, the lock screen displayed "Service Disabled" and the cellular service bars on the upper-righthand corner showed no connection. Settings won't allow me to turn on my mobile network, or even select it as it's now grayed out. It does not recognize what mobile network it should be connected to in the "About Phone" section of Settings. Additionally, the phone will not play any audio from any source, despite audio being on in the settings. It won't play ringtones, notification alerts, alarms, etc. It won't even play video files with audio in any applications (showing playback errors or just failing to play despite loading the file), in addition to locally stored videos.

I have tried restarting the device, removing and reinserting the SIM card and then restarting the device, and I just completed a factory reset, all to no avail. I am unsure of how this failure has occurred. I had believed it was a software issue, but after the factory reset I now assume it must be hardware related. I have no idea what the problem could be, or what steps I should do to fix it. I have disassembled my phone to see if anything seems amiss or damaged. The headphone jack seemed loose where it rested, but I didn't notice it until a ways into disassembly and can't rule out that it became dislodged from said disassembly. Besides a normal amount of human refuse from years of use, nothing seemed out of the ordinary in the phone's internals. Short of replacing the motherboard, I'm stumped. Any help would be much appreciated.

LG K10: Where to apply UV glue for "LG K20 Plus" screen replacement?

Tue, 16 Apr 2019 02:35:36 -0700

I've watched all the videos on youtube about replacing the screen but none of them showed where to apply the UV glue. Do you apply it to the black areas of the glass screen or what?

LG K10: My LG 10K has low memory

Fri, 07 May 2021 19:00:56 -0700

HELP! My phone LG 10K has very little apps. At one point I had more apps installed (FB, Messenger, Pinterest, Instagram, Snapchat, etc...). I then started receiving notifications I had low memory. I couldn't update, receive email, or take pictures, and was running into problems with receiving text. I have removed virtually every additional app installed a SD Card and still have problems and low memory. I've wiped out the cache and deleted anything I can think of that's extra in my File Manager. I don't have any Widgets installed, nothing on my Home screen and STILL only have very little free space.

I currently have 466 MB available out of 16GB including 4GB SD card. I mainly have the factory apps installed, some I've disabled due to low memory, and only have Snapchat, a document scanner, and 2 kid games that are additional.

The system has it uses 6.18 GB, is that normal? Snapchat only uses 543 MB, the others only 226.74 MB, my Messages 1.23 MB & Gallery is 200 KB. It says Apps are using 4.40 GB but those are mainly the system Apps.

HELP! How to I fix it to free up space to allow updates, receive emails, text and have the typical apps on my phone?

LG K20 PLUS: Why won't my phone turn on after charging?

Wed, 06 Jan 2021 17:35:41 -0700

Ok, can someone help me with this...I have an LG k20 Plus phone and just three days ago, it went dead on me (as in the battery ran out.) So I went to charge it. After around an hour of letting it charge, I decided to come back and check on it. I tried turning it on, but it won’t work. So I decided to let the phone charge overnight because I thought it just wasn't charged enough or something. The next day I tried to turn it on again but it didn't work. I also tried pushing both the volume down button and the Power key in order to reboot it, but that also didn't work. I tried everything from taking the battery out and looking at youtube videos to putting it in the freezer (again, from a youtube video). Does anyone have any suggestions for this?

LG K20 PLUS: My microphone doesn't work on headphones, when plugged in my phone?

Sun, 24 Feb 2019 23:07:28 -0700

Help! I have this game that only works with headphones with a microphone. So I tried a variety of different earbuds and headphones and none of the microphones work on my phone. The microphone on my phone without headphones in is perfectly fine by itself, but doesn t work for the game. I am able to hear through both ears on most of the headphones and earphones I tried. I had been able to use the microphone on these earphones in the past. I've even used my brother's gaming headset that works for the PS4, and the mic still doesn't work but the sound goes through. Is there anything I can do to fix this? Does it maybe have anything to do with the water damage from when I dropped my phone in a pool?
