Being able to text and surf the web at warp speeds has been very enjoyable. I've found the phone to have some things that seem bulky or what not, but all in all nothing is ever perfect. So I'm rating this 5 stars.
I only have a couple of days with it, so I cannot give a full battery's review, but like it so far. This is a fantastic cellphone for email and texting and ok overall device for the rest, including browsing and taking pictures.
If you don't text a lot or barely use the keyboard, stay away from this device. The phone screen is not extremely small but this cellphone does not really shine on that area. What you're getting is a dedicated 5 rows keyboard where typing is a real pleasure. After owning an HTC H2 (nice cellphone after rooting and running Froyo) and other HTC models, I should say ... nothing like real typing. Cellphone's screens are really responsive on these days but the problem with virtual keyboards is that you need to swap and change rows all the time so the whole typing experience changes. I was really looking for something like this and happy I found it. I thought about the HTC G2 but this keyboard is better and the hinges mechanism is stronger and way more solid. I also like the idea of having a small trackball for navigating and clicking hyperlinks; there is no trackball on the HTC G2.
It is really fast. In terms of the touch screen and Operating System, it is very responsive. You swap and change screens without major issue, I have not noticed any lag. The browsing's speed depends of many factors (area coverage, browser, etc) but this stuff is faster than my Wifi connection at home. I am getting 6Mbps; downloading or viewing multimedia content is really nice.Read more ›
it makes me sick that most reviewers on tech sites are also sold by the marketing of the sidekick 4g. they all claim what they were told: a mid-range phone great for social networking and texters.
Droid Pro: 3.1 inch screen with hideous hvga resolution. 480x640? seriously? try showing some google analytics charts on that resolution. the droid pro is basically a motorola charm on extra strength tylenol
Sidekick 4G: 3.5 inch screen with a 480x800 resolution.
processor? the sidekick 4g has the SAME processor found in the ultra popular samsung galaxy s smartphone, a 1GHz hummingbird processor. the sidekick 4g is no slouch.
only the marketing and 'youthful' UI make the sidekick 4G a smartphone for high schoolers and non-business people.
for starters.. try downloading a "home" replacement from the android market such as launcher pro or adw launcher. this will get rid of some of that kiddish user interface and will likely speed up the phone a bit.
not a fan of smartphones with sliding keyboards. they always give when in your pocket and when typing its so annoying to have the touchscreen jiggle and give when open. but since the sk4g sliding screen in surrounded on two sides this(and the strongly built slider) make the sk4g a solid slider that doesnt feel like its going to break.
the camera is sort of a downer but its not that bad.Read more ›
The original one I had would give me a 1 in 5 chance of freezing in either the browser or map (and it has crashed in Angry Birds as well), often when I am driving and need directions. Not just a regular freeze though; a 'hurriedly get the backing off and remove the battery, put it back in, and wait an eternity for the ostentatious loading screen to get me back to the home page' one (this could take two or three minutes on a good day). All of this while trying to avoid other cars in rush hour traffic. The issue was a dangerous one at that point. The lag was the second worst issue to deal with. I can live with some lag, but even after using the built in program manager to clear processes running in the background, the memory it clears is only in the single digits and would leave me with only a fifth of free memory total. The screen lock is just a pain (you have to slide an angled sliver down to unlock or up to quickly access an application and it'll do either of those in your pocket/purse) and the text layout was equally frustrating. God forbid you know anyone with more than one phone number because the drop down list for a new text does not differentiate between what is mobile, home, work, etc. Fed up with two months of ever-mounting dislike of the phone, as all of the issues happened to crop up about seventeen days after purchase of the phone, just in time to not be able to return it, I requested a replacement. Perhaps it was just a bad phone to match my luck? Negatory.
The phone I was sent as replacement was even worse than the original. It was freezing right out of the box, doing the same things as the first.Read more ›
