Avoid checking 'force gpu rendering' in developer option in android 4.x prefs, this leads to graphic problems.On S5 devices, long press the right hardware button to get the menu.

Used to be good, but key presses often get missed/lossed despite getting haptic feedback that I pressed they key. Last update was 2015, so I tried emu48 again because it is updated more frequently on Android. I have no issues with key presses on emu48 app in Android.

Unfortunately there is no menu button when installed on later Android version. Used legacy Menu Button (= symbol with box). Author: Please update to never version. go57c too

Works fine on android 10. SOLVE also works and equations don't get lost. Could look nicer with a better theme, so it looks more like the physical version.

Wonderful app. Thank you so much for your efforts. I have found this version to be the most compatible wirh the phones I have owned.

1st launch, fine, accepted command, calculation, programming. Closed with home, the wiped recent, locks on launch, alternating between recover memory and hp48 waiting hourglass over blank 48gx screen.

Haptic feedback is to slow, keys are missed if you type to fast.

Doesn't have the 'load string' operation offered by other applets.

.. asks "Try to remove memory?" at first launch. Refuses to take no for an answer. Would love to try but can't. (Update) Uninstalled and restored. Got past ram setup. Vibration feedback needs to be removed from all your calcs. Many people are complaining. Replace with audio feedback please. Keyboard a bit hard to read. Compare with skin on Droid48. Positive, this calc is a true simulation rather than emulation. It's running the actual HP binary. Upgraded to 2 stars because of keyboard.

Please remove haptic feedback it causes inputs to not register when typing fast and is annoying. Otherwise works great, no crashes unlike other emulators. Updated skin would be nice. I found I can disable haptic feedback by using the battery saver function on Nexus 5x. However I cannot disable it any other way. Hapticswitch app didn't work.

This is one of the better done ones, and it actually retains saved programs between sessions. (As it should) The feel has been massively improved too, a big bonus! The HP ROM has been freely available a while now, so it's only usability differences that distinguish between models. This is certainly the most usable. I'd buy the 48GX version, too, but I think it's a bit overpriced at the current 8 GBP. I'm sure that halving the price would more than double the sales! I am upping the rating to 5 stars!

Fast key presses result in a haptic feedback bump, but the command isn't performed. Missing entries makes this useless, even dangerous for important calcs. Lame UI look too. Look at m48 on iOS to see what a 48G emulator should be.

Adr. J. Jan 26, 2017     

Unresponsive and full of random crashes up to the point of being almost impossible to use for me (and I kept it for many months because I didn't know any alternatives)

Tre. T. Dec 21, 2017     

The response of the keyboard is too slow and the haptic feedback is annoying because I cannot turn it off.

Jef. D. Nov 22, 2015     

Now haptic feedback is turned on with no way to disable. Please fix and I will gladly rate higher.

Very stable in comparison to droid48 so far. droid48 started having issues when I purchased the Galaxy S5 and now with the S6. Very thankful someone has provided a better application.

Dan. H. Feb 13, 2017     

It would be great if the HP 49 emulator were free, as I am used to it, not to this funky precursor

Edd. B. May 30, 2016     

Works but has a gew quirks. Doesnt always register key-presses and sometimes screen is blank when opening app.

Nor. S. May 20, 2016     

Has an equation library and a constraints library built-in, If you are considering GO↑48GX. install this app first. If it works property, GO↑48GX will work.

mrI. Jan 9, 2016     

This actually works unlike the crappy droid48 app that keeps crashing on Android Intel tablets. An authentic skin would be nice, but otherwise this is perfect.

Jos. W. Nov 23, 2015     

Our developer is updating to accommodate newer versions of Android. He will read what you write and work on the problem. Send email if you are having a problem. Don't dump bad reviews.

Rav. A. Aug 1, 2016     

Has the Equation Library, the Minehunt Game, Units, Graphics and the Examples directory from the TEACH command. All for free. If you are contemplating getting GO↑48GX, try this app first. If it works well then GO↑48GX can be expected to work.

Mar. B. Aug 1, 2016     

Loads up asking to try recover memory (displayed on Calc screen), but ignores all key inputs. On an s7

Les. L. Jan 21, 2016     

Have several actual 48g and gx calculators so this makes it readily available. Once this proves out on S5 I will purchase gx version.

Sam. L. Oct 1, 2016     

Quick key presses are unreliable and sometimes a key gets stuck in the down position

jsv. Nov 21, 2015     

I was using the app on a Nexus 5, android 6.0 with no problems (great app, thanks). The 1.1.0 update made it unusable. Keys now have haptic feedback, and the response is awful (1/3 of the touches produce vibration but are not recognized by the app). Uninstalling :-(

Bri. K. Sep 28, 2016     

Just like his other calculators. Hopefully he fixes it.

Xav. P. Jan 1, 2016     

Latest update has hepatic feedback which constantly forces me to slow down every type my last entry. Also it does not have a menu key for those phones that don't have a physical menu button it makes it impossible to access the menu

Ray. f. Nov 22, 2015     

Seems to work OK, but it jiggles around when you press a key, and, even worse, beeps when you make a mistake. And there is nothing at all you can do to stop it! Even though everything possible on the phone is set to 'silent'...
