As a user of the testing version on Google play, I just got a notification that this app wants new permissions. Suddenly this looks less like a calculator and more like spyware. In one update, you've added internet access, location reporting, account/data access, and filesystem access. And yet, your change notes fail to mention a reason for any of these. As someone concerned with privacy, I would appreciate some kind of explanation.

Looking at your repository, it would be nice to see your default branch switched over to the only active branch you have, and it would be even nicer to see downloadable releases (or at least tags that match your play store releases) and a changelog.

I'm having a hard time figuring out where I can find the graph feature. The app description says you can swipe left and right to access more panels but there's only one at the right with the same options as the standard calculator except for a plus that creates a bar at the bottom that leads to one more panel with with some letters (no x and y though).

I have the F-Droid build of Calculator 4.3 on my phone and Avast! Mobile just started identifying it as containing a Trojan today. It has been on my phone since July without a previous report. I have also reported this to F-Droid. The specific notice is, "Trojan detected - Android:Revtcp-A [Trj]". I have no idea if this is a false positive or an actual problem.

I have version 4.3 which I have been using happily since 2014 in blissful unawareness of later versions - thanks for a great app!

Now, having just installed CM 12.1 on a spare device, I expected to see the same old calculator but I didn't.

So it looks some of the nice functions (e.g. matrix) in 4.3 disappeared with the merge with lollipop code and the CM version diverged from this one shortly after (nov 2014?).

If I sideload my 4.3 apk, the Google Play Store wants to update it to 5.1.1 (but I've set the Play Store not to update).

I'm confused because 4.3 (com.android2.calculator3) appears richer (therefore better?) than the latest here (com.android2.calculator3 version 5.1.1) and the latest bundled with CM (com.android.calculator2 version 5.1.1-eb9065775b).

So I just wonder what's happening.

• What are the differences between the version here and the one on CM?
• Is the functional line in 4.3 going to be reinstated at some point and is that going to become the CM standard.

I'm not complaining, just interested. Thanks for the great app.

(4.3 is accessible on F-Droid for anyone interested)

The Calculator can't handle negative Numbers in Matrix Multiplications: e.g. [[1,2][3,4]]x[[-1,2][2,-1]] gives the result: [[NaN,NaN][NaN,NaN]]

-unverified, reported from app store

This would also include spaces every 2 characters in hex and spaces every 4 characters in binary. Include it as an option in settings, defaulted to off. Biggest issue is that the delete key would mess up comas big time. Maybe include them in onDraw? Use the dec-hex-bin code to get numbers out of the equation, and then split at the decimal.

first i should tank your . i see matrix classes and layouts in source code but where is in UI ? i change switch (v.getId()) { case R.id.btn_advanced: layout = advancedPad; break; case R.id.btn_hex: layout = matrixPad; break; case R.id.btn_matrix: layout = matrixPad; break; case R.id.btn_close: // Special case. This button just closes the tray. showFab(); hideTray(); return; } this code to see matrix page , but seems it is not ready ?

On the calculator app, we have this key layout: https://lh4.ggpht.com/hyeVjYhhjUBEX15vgG1whZXBSMdAYX8VLrpdfOdJ7xDtGHVgz6c4ZfTd3tS_Krzvibk=h900

The problem is most calculators look like this: http://i1.ppfry.com/media/catalog/product/c/a/800x880/casio-hand-held-calculator-hl-4a-casio-hand-held-calculator-hl-4a-0y9hnd.jpg

You can see the 0 is on the left, while the dot is between the = and the 0. It's the same on a numeric pad on a computer : 0 on the left, dot on the right.

Since the calculator app is doing the opposite, it's quite confusing. Could it be possible a add an option to select the preferred layout?

When dragging the Calculator icon down to delete it, if Cyanogenmod expanded desktop is activated, the circle with cross is shown too far down (see screenshot)

My phone (LG Optimus Dynamic II model L39C Tracfone) has the old-school 320x480 display resolution. This is a 3:2 ratio instead of the newer 16:9 or 16:10 screens. The issue is that the wrong elements are trying to scale down, causing a visual mess. The text box padding and history bar should scale, and the font as well. Instead I get a squashed graph, ridiculously huge history bar, and the button text overlapping. I'd attach a screenshot but I am sending this from my phone. I might try to attach one later.

I also hate the new icon.

Steps to reproduce: -Add a widget to lockscreen -Copy text (so that "paste" will show up in an EditText) -Go to the lockscreen and minimize the page with the calculator widget -Hold down on the EditText until the cursor + paste appears -Click paste -CyanogenMod reboots

Hello , I enjoy using this app, it is very useful for me! However, I found a misleading widget in this app. I thought "DEC|RAD" in the upper left corner was not clickable, but I was surprised to find that it actually toggles "RAD" mode and "DEG" mode. I think users may be confused when they activate it inadvertently, under the misconception that they are only used to show the state. So, just as a personal suggestion, could you try to redesign the widget? And thanks for your useful app!

Please add support for icon shape

you should fix it to upload new version to google play https://www.xda-developers.com/google-play-app-updates-must-target-android-8-0/
