To simply answer the question, no. You can put a brand new seal/adhesive in the back glass/rear housing, but it’s not guaranteed that it will be waterproof. Unless you have some kind of press that holds the parts together until it binds properly. Just speaking out of experience, opening a device that has been opened before is a lot easier than one that has never been open. Hope this helps. Keep it out of water.
Sounds like your display is just damaged. Only way to verify that is to slap on a replacement screen and see. You can 1) Order a screen and attempt to fix it yourself 2) Browse your area for a mobile repair shop. Google Pixel 3 Screen Replacement Looking at the guide, I would say if you have not done this before to let someone else do it. Of course, screen repairs are not cheap, but I would trust someone who has a good repair rep to handle this for me. You can even discuss it further with the chosen repair shop to see what else they can offer you. Back up data and transfer to another drive, etc. Hope this helps.
As far as I know, the battery needs to be roughly 10%-15% charge for thermal activity. It does not appear the be punctured, but of course you still want to be safe. I think it will be okay, assuming that you did not see any abnormal. Swelling, smoke, smell of rotten eggs, etc. If you are looking to remove the battery. I would recommend you grab some 99% isopropyl alcohol and just apply a very small amount around the battery to let the adhesive soften. It will make removing the battery a lot easier. If you want to give it a go and try to examine the board yourself. You can use the 99% isopropyl alcohol and clean the boards. You can tell where the areas are affected, you will see white/green odd looking marks. Clean it with a soft tooth brush and 99% alcohol, let it dry up before connecting anything and test. Hope this helps.
Most LCD’s are called assembly when the screen is paired with the frame of the phone. From the looks of this, it’s almost similar to the Samsung devices. If the frame of the device has been bent/damage, there is a chance that the LCD repair may not go well if the LCD cannot sit properly on the frame. This is when you get a LCD Assembly to replace screen and frame together. Can you replace it yourself? - OF COURSE!!! I’m sure you can find the part anywhere online, depending on your location. Here is one from Witrigs (https://www.witrigs.com/replacement-parts-for-oneplus-6t ) If you are confident to do the repairs go for it! The cost of the screen is almost the same.
The only thing that comes to mind is software or hardware. I would back up the phone on smart switch, then run factory data reset. I would test it first before actually restoring the data back on the device. If it seems to be fine, I would continue to restore the data EXCEPT for Apps. Test again and see if everything is working accordingly, then proceed with Apps to see if the issue persists. Check if there are any updates on the software. If it does persists after factory reset, it could be a chip related issue (assuming the device has not damages on it). If possible I would try to push for Warranty if that still applies and notate all the test you did. Hopefully this helps. Good Luck
If you have the sim card’s card the PUK Key is on the back along with the IMSI. If you don’t have the card anymore, contact your carrier and they should be able to tell you what the PUK Key is. I think, by default, the PUK Key is 1111. If you changed it yourself, or someone who accessed your phone, you will most likely need to replace the sim card.
I’m pretty certain there is a way to manually reset the pairing on your watch. Just like any other bluetooth device it should be capable of doing so. Re-pairing instructions I found online (1) Open Garmin Connect app; (2) Double tap on the face of the Vivosmart to activate the device; (3) Press and hold the face of the Vivosmart until the settings options appear; (4) Swipe through the settings until you see the Bluetooth symbol; (5) Press the Bluetooth symbol; (6) Press the right arrow once; (7) Touch Pair;
Blank screens after drops are common after a pretty hefty drop. Are you noticing anything vibrations when turning on the device? If so, it could mean that your LCD is just damaged and needs to be replaced. You could also attempt to see if there are any cracks behind the glass with good lighting. If you’re able to get another LCD that would be a way to determine it. The other test is if you have another A5 you can swap your board over to make sure it isn’t board damage related. This is just to knock out any other issues with the device. Good luck
