That Nokia code is a myth, it doesn't provide you with any more power, it actually does more harm than good if you are low on battery because it activates the better voice codec (which consumes MORE battery). However, on Android you have this feature called Battery saver. Here's my settings screen for this function on a LG phone (accessed by going to ...

You can be 99.9% sure the touchscreen is fine. Battery wasn't damaged too. If the touchscreen still behaves erroneously after unplugging, then rubbing it with a soft cloth should help. This is a common issue with cheap chargers. It indicates that charger may not be safe to use with any device - it may catch fire or explode. Prolonged use of such chargers ...

In my experience, and my extensive reading on the subject, it seems to be related to the charger and not the cable, unless the cable is a non-standard USB cable. Samsung does not use a special cable for their micro-USB chargers, only their old devices with the Apple-like connector. The USB standard requires handshaking to negotiate more than 500 ma of ...

There is more to an adapter than just the current, although kudos to you for knowing that much. The problems arise due to the fact that the USB-2 spec is for a maximum of .5 A at 5 V without some extra handshaking to ascertain that the device wants and can handle more. For Apple devices, this is done in a certain way according to their "standard", which is ...

There are various apps on the play store where you can check your current charge current and your "maximum" (not sure how accurate the calculation is) Via USB the maximum is 460mA with a average of 460mA Via AC the maximum is 1000mA with also a average of 1000mA

yes, it is absolutely safe to charge a device with a charger that has more current capacity than needed. Ohm's law tells us the relation between current, voltage, and resistance: I = V / R (current = voltage / resistance) Since the voltage is held constant (5V), the only factor that determines current draw is the load (another term ...
