I've dropped my tablet into the water. It keeps restarting. What is the chance of saving it?
I can tell you a little story:A friend of mine accidentally dropped his smartphone in a pool, it was completely submerged, after very quickly picking it up....the most immediate advise we got from both the web and those so called "experts" was:a) DO NOT turn on the device (which I think you have done already, sadly). If you turn it on, electricity starts to flow possibly short-circuiting stuff and damaging the device. This is because most water can conduct electricity to certain level, because it has salts and other stuff diluted (unless it is distilled water).b) If possible take out the battery, to, again, protect it from turning on. Dry everything with a towel as best as you can.c) Drop the device and battery into a bowl (or a bowl for each) or recipient full or RICE, yes, RICE grains...so, the device kind of stays in the middle completely surrounded by RICE...like floating in RICE ..I think you get the idea.d) Leave it there for a couple of days in a dry environment and getting as much sunlight (for the heat) as possible.Explanation: RICE will absorb humidity, sun heat will help with water evaporation and whatever humidity is left there will be absorbed by the RICE grains.After a few days, take it out of the rice bowl, put in the battery and turn it on.There is a high possibility that, if it was not damaged initially with the immersion in water, and now, full dry. It will work fine.Sadly, if something was damaged by a short-circuit when turning it on initially, after it became wet or while it was wet (at least some parts...), then your device is damaged for good.In my friend's case, his phone turned on perfectly after a few days of drying in RICE grains and worked perfectly. But, that was just his case.If you decide on trying this, AT YOUR OWN RISK, let us know how it works.Good luck.
No network coverage, emergency calls only." What does it even mean? How can calls be made if there is no network at all?
It means that there are signals of same technology (GSM) there from other network providers, and you are camped to it in limited mode on it, so that you can make that emergency call.This feature was commanded by the GSM technical group since its creation, so that you can make a special call even if you are in area where your service provider dose not have coverage.Of course this happens after phone fails to camp to its Home network (the carrier SIM that's inside) or Roaming network (your carrier has tie ups with other carriers around the world).In Short any mobile (mainly GSM) works this way.. First : -- Home Network , if not available then,Second : -- Roaming Network, if not available then, Third : -- Camp to network with best signal in Emergency Mode, if not then,Fourth : -- ' No signal'. Meaning at a place where there is no signal at all.
