So I have a tablet here at work that was brought to me with an issue. It powers on, works properly, has no issues with the...

Unfortunately, this can mean a few things. But! Here are some suggestions and things to try to save the trip to your carrier or a whole loop of going back and forth. (1) Make sure the SIM Tray is properly seated and is fully slotted in. If there is resistance or it is not fully seated, there may be debris in the port. (2) Check inside the slot carefully, see if there is any debris lodged in there as it can be keeping the SIM from being recognized. Carefully remove debris. (3) Clean the SIM Card. First off, I would inspect it. Any noticeable discoloration or damage would indicate that you will need a new SIM, but a small smudge or a piece of debris can be removed! Taking a soft, non abrasive cloth and cleaning the SIM gently. (4) Update the iPhone to latest iOS Release. Sometimes all you need is an update to correct any faults. Hope this helped! Good Luck!

With a few google searches - I was able to find some interesting reads that would certainly help you as you are not the first. A forum post of an individual that unfortunately had a pressure spot, a few people helped him out and were pretty insightful (chris/@bobcat1981 makes some great suggestions and detailed answers on how to do it) Pressure spot on iPhone after screen replacement.. Also, properly following the iFixit guide will defiantly lead to a greater success. iPhone 7 스크린 교체 Hope this helped! Good Luck!

You may want to identify what exactly happened to the device - ideally what lead to the component not being able to function. That way, I could bring a more informative answer. But all is well - here are my suggestions for you as repairing it isn’t exactly practical.. Have you tried to clean any debris out of the port? That would be the first thing you should do to get it out of the way. Things like air duster (being gentle) and or a cotton swab can help get anything clinging inside the jack.

First, you should check if the device is in flight mode and if the SIM card is properly seated. Also try resetting and booting into safe mode.: Safe Mode for ZTE Prestige 2: (1) To enable the Safe mode, with the device Turned On, press and hold the Power key until the Power menu appears. (2) Tap and hold Power off. (3) Tap OK. (4) The device will restart in Safe mode, press and hold to unlock the screen. (5) To disable the Safe mode, press and hold the Power key until the phone turns off. (6) The device will reboot into normal mode. If that fails, you can try a Dial method. This method requires you to open the dialer first after which the below steps is to be followed. (1) Enter this code *#*#4636#*#* in the dialer (2) Enter Service mode (3) Click on the top option, – Device information or Phone information (4) Next, tap on Run Ping test (5) Radio option will be visible at the bottom of this screen (6) Check if it is off or on and then press the button next to it to turn on radio. (7) You will be prompted...

It sounds like an all around software failure. Try to throw the tablet into safe mode (1) Power off the device, wait 3 seconds. (2) Power on the device and wait for the "Samsung" boot logo to appear, often heard with a chime. (3) Immediately press and hold the "Volume Down" button until the device continues to boot or at least 5-10 seconds. (4) In the lower left corner, it should say "Safe Mode". (5) Try to interact with the device as normal Does the tablet still have bugs or failures with safe mode on? (Your tablet might be doomed for replacement..)

Technology - Simple, but complex. It sounds like she broke it's last leg with the final drop. If the laptop isn't pulling a charge, I would've thought that the connector went bad even if it showing accurate readings. Then again, this may be more damage on the hardware like the motherboard if it is failing during or after POST. I had a Compaq laptop (remember those?) years ago and the same thing happened. I tried to fix it, ended up trashing it. Salvage the HDD or SSD, the RAM if it's usable (maybe that's causing the post crash? - Just a thought.) and tell her not to drop her next laptop.

When interacting with the buttons, does the device still make sounds or vibrate? This could be an LED Screen Failure.
