There are several factors, which I'll address (pun intended) in no particular order. RAM is expensive Sure, memory chips may be cheap, but that's not the only (or even the main) cost. Alongside the RAM itself you need extra buses, power lines, bigger memory controllers, heatsinks, &c. The RAM also takes physical space on-chip. For oomph-per-dollar, at ...

Motorola Droid 4 XT894 has 1785mAh battery with 2% tolerance i.e 1735mAh actual battery capacity. Your seller seems to have fooled you. Also it doesn't seem like the seller put up the battery description as 3300mAh by mistake as he has put this in Title name itself You could have taken out the battery from phone and flipped it to see the battery capacity ...

uname -m will display the architecture of the running kernel. This is different than whatever your hardware may be capable of running. Unfortunately, you have to know which architectures are 32-bit and which are 64-bit. But you can easily find this out. For example, my m7 displays arm7l. A quick search confirms that this is a 32-bit architecture, meaning ...

Android does, but it's not very well documented. The ConnectionService class was introduced in Marshmallow and allows an app to register itself as a voice service, the user needs to manually enable the voice service through the phone settings (same place you would enable/disable SIP accounts). Once this is done you can choose between registered voice ...

All computers have a special piece of hardware called the clock (more fully, the real-time clock or RTC). The clock is connected to the CPU, but it runs even when the computer is completely powered down. On a desktop computer, a battery on the motherboard keeps the clock running even when it's unplugged from the mains. Mobile devices tend to have a large ...

On desktops and laptops, drivers are a necessary evil. Hardware is often user-serviceable and prone to changes, and there is a huge variety of possible combinations. On phones and tablets, this isn't quite so. You can't really change the hardware easily. It's entirely safe to disallow driver installation since you don't really need it. It is a lot easier to ...

As devnul3 says, a power-only cable is a USB cable where the data pins are not connected. The main reason they exist is because they can be made ever so slightly cheaper by virtue of only needing 2 connections instead of 4 (and also because you don't need to worry about preserving the quality of the very high frequency signals on the data lines). This said,...

This may not be as easy as you think. The eMMC is connected to the board with a Ball Grid Array (BGA) connection, which is pretty difficult to reconnect once removed. You can see photos of the chip and more discussion on the topic on this XDA post. As for where the chip is, you might be able to find it on some teardowns, but my eyes didn't catch it in ...

The "Hardware Backed Credential Storage" aka "Android Key Store" is only hardware backed when the hardware on the device has the necessary hardware components in it. When there isn't the necessary hardware available it falls back to software storage. Android also now supports hardware-backed storage for your KeyChain credentials, providing more security ...

The list from the Drammer app mentioned in your first link, shows some devices are not vulnerable, E.g, HTC Desire 510.( Row hammer wiki suggests that ECC overcomes TRR mentioned below the table) Quoting from Source We encourage everybody to try our Drammer test app and help figuring out how widespread mobile Rowhammer is. We expect, for example, that ...

It seems like a hardware issue (not directly related to storage), better try to get fixed. Unless the device boots at least to some bootloader stage (like fastboot or odin or edl) you can't access its memory. Or if the data is extremely important, contact some professional data recovery service which usually do one of the two: Access eMMC directly using ...

My answer for you is twofold; there are innate downsides to off-brand devices but - most importantly - your use case (development and application purposes) might make off-brand Android phones a poor choice. This is from my experience with the phones (I have a lot, having lived in Asia for years, and seeing a lot here in the States) First, the general ...

You shouldn't worry that much as it happened once. Just take care it doesn't happen often. In short, LEDs have a long life span (20k+ hours?). So the concern isn't really the LEDs burning out (although after a long period of time, they will eventually start losing the amount of output and their brightness will dim). The real concern is to not apply too ...

It's a chip soldered to the main board in the phone. You can only remove it by desoldering it from the board in a soldering oven. (This is a precisely temperature-controlled device: a kitchen oven won't do.) Even if you did manage to desolder it safely, the chip itself isn't a lot of use to you. Because it's an internal component, it doesn't fit into a ...

You retain your groups if you have the same number. Off-topic, you may also want to check the official documentation on how to back-up and restore your chat history to the new phone.

The second microphone is used for noise cancelling. The phone uses it to listen to the external environment (not including your voice), so that it can filter that out from the sounds it hears using the main microphone. That way, it can reduce the amount of noise that comes with your voice, and make your call more audible to the other party.

Congrats! You won 10 bottles of snake oil if you're lucky. Honestly: this has two very clear indicators of being scam: There are no viruses on Android. And even if there were, how should that website know? Asking you to download an app via their specific link to fix {whatever}. If you do so, then you are in trouble. Ignore that message (close the tab of ...

SMART was originally designed for ATA devices and extended to SCSI and PCIe/NVMe later to cover almost the whole range of HDDs/SSDs. Trying to send SMART commands to eMMC, e.g. using smartctl would throw error: Unable to detect device type. Please specify device type with the -d option. Unlike SATA or SAS, eMMC communicates over parallel links and has a ...

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 for ...

My favorite is the AIDA64 app. I've been purchasing Android boxes (>10 makes/models in last 6 months) and testing/vetting them for friends. Heard the expression, "Mutton dressed like lamb"? It describes many of what's crossed my bench. The screenshot is of an AIDA64 scan done on an "M8S" box advertised as featuring an Amlogic S812 CPU. This app was one ...

Given that McAfee himself (who has had nothing to do with the software for years after selling it to Intel) describes the product as "the worst software on the planet", I'd take the refund and be grateful at dodging that bullet. I won't recommend a particular one, but you could buy six copies of a competing Android security product for what a year's ...

As well as noise cancelling, some phones also use the two mics to record sound files and videos in stereo.

The OS isn't relevant to charging speed, but the internal hardware differs heavily between phones. One thing you'll experience is that nearly all chargers that advertise themselves as 2.1A are optimized for iProducts, which require a different grounding scheme in the charger to reach their full speed, and that same scheme limits Android devices to 500mA. So ...
